Part One: The Trial

Dr. Nathan Cole had always understood the body better than he understood other people.

At thirty-one, he was already the youngest senior researcher in the hospital’s experimental medicine division. He could explain hypertrophic signalling pathways from memory, identify obscure neuromuscular diseases from a single blood panel and read biochemical papers in three languages. His measured IQ was 145, a figure he pretended not to care about but remembered with perfect clarity.

Nathan was handsome in the careful, understated way that made other men look twice: neatly parted brown hair, pale blue eyes, a lean frame hidden beneath blue scrubs. He had dated other doctors, briefly, but none of them tolerated coming second to his research.

His last boyfriend had accused him of treating intimacy like another experiment.

Nathan had answered that experiments were at least predictable.

For fourteen months, he had been developing Compound H-17.

The serum was intended to reverse severe muscle wasting. Unlike anabolic steroids, it did not merely increase protein synthesis. H-17 reactivated dormant developmental mechanisms, forcing adult muscle tissue to behave as if it were still being formed for the first time. In mice, it restored almost complete mobility within days.

Then the doses became stronger.

The final animals had developed bodies three times their original mass.

Nathan had terminated them before behavioural testing could be completed.

He told the ethics board the project had reached a temporary dead end.

He did not tell them that he had already reformulated the compound.

Late one evening, when the research wing was nearly deserted, Nathan stood alone beneath the laboratory’s white fluorescent lights. A flask of luminous blue solution rested in his hand.

The colour was only a marker dye. It should not have looked alive.

Yet the fluid seemed to brighten whenever he touched the glass.

Nathan added the final reagent with a pipette, watching a thin blue thread disappear into the mixture. He entered the result into his computer, recalculated the molecular stability and checked it twice.

Projected muscular increase: 18–24 percent.

Expected neurological penetration: negligible.

The figures were perfect.

He transferred a small amount into a purple collection tube and placed it in the centrifuge. The machine began to spin with a rising mechanical hum.

Nathan watched it.

He had spent too many years reading about men who had discovered something extraordinary and lost control of it to committees, corporations or frightened administrators. The hospital wanted another six months of animal trials. The pharmaceutical sponsor wanted ownership of the formula. The ethics panel wanted caution.

Nathan wanted proof.

When the centrifuge stopped, he filled a syringe.

He sat in the laboratory break room, rolled up his sleeve and regarded the needle for several seconds.

“This is forty percent of the calculated therapeutic dose,” he said into his phone’s recorder. “Subject is a healthy adult male, thirty-one years old. Baseline weight, seventy-eight kilograms. Baseline cognitive testing completed this morning. No cardiovascular abnormalities.”

He hesitated.

Then he inserted the needle into his arm.

The serum entered cold.

Nathan removed the syringe and pressed cotton against the puncture.

Nothing happened.

He waited five minutes.

Ten.

At fifteen minutes, he smiled.

“No adverse reaction.”

At sixteen minutes, his stomach cramped.

Nathan bent forward sharply, both hands pressing against his abdomen. The pain was not digestive. It was deeper, as though every muscle inside his torso had contracted at once.

He tried to stand.

His thighs tightened beneath his scrubs.

The fabric pulled against them.

Nathan froze.

A heavy pressure spread along his forearms. Veins surfaced beneath his skin, thick and dark. His fingers trembled as his biceps swelled, pushing outward against sleeves that had fitted loosely moments before.

“Oh my God.”

The pain intensified.

His shoulders widened with a series of muffled internal pops. The neckline of his scrub top tightened around his throat. His chest pushed forward, becoming broad and unnaturally dense beneath the thin blue fabric.

Nathan stared at his arms.

They were no longer lean.

They belonged to a man who had spent decades lifting weights.

His breath came faster—not from weakness, but from panic. His heart felt powerful rather than strained, each beat thudding through his expanding chest.

He reached for his phone.

His hand knocked it from the table.

The small device skidded across the floor.

Nathan stared at it, bewildered by the clumsiness. His fingers had grown thicker within seconds. The tendons in his hands stood out like cables.

He bent to retrieve the phone.

His back expanded.

The scrub top tore slightly beneath one arm.

Nathan gasped and pulled at the fabric, trying to inspect the damage. His reflection in the dark television screen showed a body rapidly becoming too large for the chair.

The serum was not producing eighteen percent growth.

It was still accelerating.

“Stop,” he whispered.

His abdominal muscles tightened so violently that he nearly vomited. Hard ridges formed beneath his clothing. His thighs pressed together, filling the scrub trousers until every seam strained.

Nathan attempted to calculate the progression rate.

Initial onset at sixteen minutes. Approximate increase—

The numbers would not settle in his mind.

He knew what he wanted to measure, but the equation seemed to slide away whenever he reached for it.

Fear replaced concentration.

He stumbled toward the bathroom.

By the time he reached the mirror, his shoulders nearly filled the doorway.

Nathan gripped the sink.

The face looking back at him was still his, but larger. The neck had thickened until the muscles rose toward his ears. Fine lines appeared across his forehead. His jaw looked wider, heavier and older.

He touched his cheek.

The skin felt rough.

“What is happening to me?”

A hot itching sensation spread across his scalp.

Nathan dragged his fingers through his hair.

Several brown strands came away.

He stared at them.

More hair fell onto the sink.

Nathan clawed at his head, but every movement loosened another handful. His carefully styled hair collapsed across his forehead, thinning visibly as he watched.

“No. No, no—”

Within a minute, the entire front had receded.

The crown followed.

Hair slid over his shoulders and collected around the drain. What remained shrank into scattered patches, then disappeared entirely.

Nathan’s palm met bare scalp.

Completely bald.

His face continued to age around his widening eyes. Lines deepened beside his mouth. The bones of his brow pushed forward, giving him a harsher expression even while terror contorted his features.

The muscular growth showed no sign of stopping.

His arms were grotesquely large now. Veins branched beneath the skin from wrist to shoulder. The fabric around his sleeves had stretched into narrow bands that cut into the expanding flesh.

Nathan screamed at his reflection.

The sound was deeper than his old voice.

He tried to think of the receptor antagonist stored in laboratory refrigeration.

Its name escaped him.

Nathan knew there was an antidote candidate.

He had designed it.

He could picture the bottle. He could remember the shelf. He could remember explaining its mechanism to his assistant.

But the mechanism itself had vanished.

He ran back into the laboratory.

The computer displayed streams of metabolic data from the sensors attached to his wrist. Growth hormone signalling had exceeded every projected threshold. Muscular density continued to rise. His weight had increased by more than thirty kilograms.

Nathan stared at the graphs.

He understood that they were dangerous.

He could no longer understand why.

One line climbed sharply across the screen.

Another descended.

The labels seemed overly complicated. Too many syllables. Too many numbers.

His frustration hardened into anger.

“Make it stop!”

The computer continued producing warnings.

Nathan struck the desk.

Metal buckled beneath his fist.

He recoiled, shocked by his own strength.

An alarm began to sound.

The noise hurt.

The red warnings flashed faster.

Something inside Nathan snapped—not a bone, but a restraint. Rage flooded him, simple and overwhelming. The machine was making the noise. The machine was refusing to help him.

He grabbed the monitor with both hands.

Some distant, intelligent part of him knew the screen contained the only complete live record of his transformation.

That part was already too weak to stop him.

Nathan tore the monitor from its stand and smashed it against the edge of the bench.

Glass exploded across the laboratory.

He struck it again.

And again.

When the alarm finally died, Nathan stood panting among the fragments.

He looked down at his hands.

“What did I…”

The end of the sentence would not come.

Footsteps approached in the corridor.

Nathan fled to the changing room.

His scrubs had become painfully tight. He tore them off with more force than necessary, ripping the shirt from collar to waist. In his locker he found a white compression shirt and black athletic trousers.

He did not remember putting them there.

The shirt stretched across a chest that had become massive and barrel-like. His shoulders were wider than some doorframes. His arms hung thick and heavy beside him, each one larger than his old thighs.

His body looked like that of a competitive bodybuilder in late middle age.

Nathan touched his smooth scalp.

He remembered having hair.

He could not picture its colour.

The laboratory doors opened before he could escape.

Dr. Priya Shah entered with three technicians. Their expressions shifted from alarm to disbelief.

“Nathan?”

He backed away.

“Don’t touch me.”

“Nathan, you need to come with us.”

“I’m fine.”

“You’ve triggered a chemical exposure alarm. Your workstation is destroyed.”

Nathan looked past them toward the broken laboratory.

“I didn’t do that.”

Priya glanced at his swollen arms.

“We have security footage.”

Nathan’s face tightened. Thinking had become exhausting. Every question felt like pressure behind his eyes.

“Turn it off.”

“Turn what off?”

“All of it.”

The researchers moved carefully around him. One held a clipboard. Another wore protective glasses and gloves. They seemed small and fragile.

Nathan followed them only because Priya spoke slowly.

In the examination room, they took blood from an arm so thick that the tourniquet barely encircled it. They scanned his chest, measured his heart and attempted to calculate his new body mass.

One hundred and thirty-six kilograms.

Nearly all of the increase was muscle.

His blood pressure was high but stable. His heart had enlarged proportionally. His bones had thickened. Even his connective tissue had been reinforced, as though the serum had rebuilt him according to some monstrous interpretation of physical perfection.

Nathan sat beneath the scanner while the staff discussed him through the glass.

He understood isolated words.

Hypertrophy.

Neurotoxicity.

Cortical degradation.

The final phrase made him uneasy, although he could no longer have defined it precisely.

A neurologist displayed the brain scan.

There was no tumour. No bleeding. No obvious tissue death.

But the metabolic activity in Nathan’s frontal lobes had fallen dramatically.

“It appears the compound redirected resources,” the neurologist said. “The muscular growth required enormous amounts of glucose, amino acids and cellular energy. His brain wasn’t damaged in the conventional sense.”

Priya stared at the scan.

“Then what happened?”

“Neural pathways are being simplified. Redundant connections are disappearing. Higher cognitive functions are being sacrificed to support continued physical adaptation.”

Nathan listened from across the room.

He knew they were talking about him.

He did not like the words they were using.

“Am I okay?” he asked.

No one answered immediately.

They administered the cognitive test in a private office.

Nathan remembered taking similar examinations before. Once, they had seemed almost insulting in their simplicity.

Now the geometric patterns made his head ache.

He could not complete the number sequences.

He forgot instructions halfway through tasks.

When asked to define an abstract concept, he repeated one of the words from the question.

His frustration mounted until sweat ran over his bald scalp.

“This test is stupid.”

“Please try the next problem,” the examiner said.

“I said it’s stupid.”

Nathan gripped the sides of his head.

For an instant, he remembered lecture halls, research papers, long nights spent mastering information that other students found impossible.

Then the memory lost its details.

He knew he had once been clever.

He could no longer remember what cleverness had felt like.

The examiner placed the clipboard on the desk.

Priya stood beside him, pale and silent.

Nathan looked from one scientist to the other.

“Well?”

The examiner turned the page around.

Previous recorded IQ: 145

Current measured IQ: 71

Nathan stared at the numbers.

He recognised that the second was smaller.

It took several seconds before he understood that it was supposed to represent him.

“That bad?”

Priya’s eyes filled with something he hated more than fear.

Pity.

The neurologist glanced at the live readings from Nathan’s neural monitor.

“The decline may not have finished.”

Nathan looked at him blankly.

“What decline?”

No one in the room spoke.

Behind them, the monitor registered another small reduction in frontal-lobe activity.

Nathan’s enormous hands remained clamped around his head as the final fragments of the man who had created H-17 struggled to understand what he had done.

The serum had worked.

It had made his body stronger than he had imagined possible.

And it had already taken away enough of his mind that he could no longer remember how to reverse it.

Dr. Nathan Cole was discharged six days after the trial.

“Discharged” was not the word the hospital used. Officially, he remained under observation, subject to daily scans, blood draws and neurological monitoring. Unofficially, nobody knew what else to do with him. He was stable. He was not infectious. He was monstrously strong, but no longer overtly violent unless overstimulated. Most of all, he was no longer the kind of man who could explain what had happened to him.

Nathan signed the release papers with a hand so large it cramped around the pen.

His signature looked simpler than it used to.

Outside, on a bench beneath the summer trees of the university medical campus, he sat in a tight white shirt and black athletic pants and stared at his own forearms. Thick ropes of veins coiled beneath the skin. His chest pressed against the fabric so hard it looked vacuum-sealed to his body. Students passed on the path nearby, glancing at him, then glancing again.

He could feel their eyes.

That part, at least, was easy to understand.

Before the serum, people had looked through him. He had been handsome, yes, but self-contained, abstract, intimidating in an intellectual way. Now they stared openly. Men looked impressed. Women looked alarmed. Everybody noticed him.

Nathan touched his bicep almost absentmindedly, then flexed.

The muscle jumped beneath the sleeve like something alive.

He grinned before he could stop himself.

A week ago, that reaction would have horrified him.

Now it felt good.

Adjustment came faster than shame.

He still mourned the things he had lost, but not with the clarity he once would have brought to tragedy. He knew his thoughts had changed. He knew there were words that used to come easily and now got stuck halfway to his tongue. He knew that reading scientific articles had become exhausting. The abstracts blurred. The conclusions slipped away before he reached the second paragraph.

But there were simpler pleasures.

The gym, for one.

At first he went only because Priya had recommended “controlled exertion.” She had meant physical therapy, carefully supervised resistance work, cardiovascular testing and monitored strain response.

Nathan heard only gym.

The first time he stepped into the university fitness center, conversation dipped around him. He was wearing a plain white compression shirt that clung to every exaggerated contour of his torso. His scalp gleamed under the fluorescent lights. His shoulders nearly brushed the machine frames as he passed. Students stared openly from the treadmills.

Nathan sat down on a bench, took a dumbbell that an ordinary man would have needed both hands to lift and curled it once experimentally.

It rose too easily.

He took a heavier one.

Then another.

Within minutes he was grinning like an idiot, repping weights that should have pinned him to the floor. His massive arms swelled and tightened with each movement, veins surfacing, chest pumped full and round beneath the tight fabric. The fear that had clung to him since the transformation retreated, replaced by a hot, stupid pleasure.

This, at least, made sense.

Weight went up.

Muscle worked.

People stared.

Nathan liked all three.

That was how Dave noticed him.

He hovered beside the bench after Nathan’s third set, lean and wiry in a grey sleeveless top and navy gym shorts, a white towel looped over one shoulder. He was probably twenty-two, maybe twenty-three at most—young enough to look almost delicate next to Nathan. His face was open and clever, with dark eyes that moved quickly and a crooked smile that made him look more mischievous than confident.

Nathan looked him over with blunt interest.

Dave laughed nervously. “Jesus. Those are not human reps.”

Nathan snorted. “Maybe not.”

Dave hesitated, then stepped closer. “You’re Dr. Cole, right?”

Nathan’s expression flickered. It still surprised him when people knew that name.

“Used to be.”

“I’ve seen you around the science buildings.” Dave nodded toward the dumbbells. “And I heard… stuff.”

“Stuff?”

Dave grinned. “That you got huge.”

Nathan barked a laugh at the simplicity of it.

“Yeah,” he said. “Guess I did.”

Dave should have looked frightened. Most people did. Instead he looked fascinated. Admiring, even. He stood there asking questions Nathan only half understood and answering his own with a speed Nathan could no longer match. He was a final-year biochemistry student, he said, working a lab assistantship. He spent too much time reading papers and not enough time filling out his T-shirts. His friends called him Skinny Dave.

Nathan liked the way he said it—half-joking, half-resentful.

Later, when Dave brought him a sports drink and sat beside him on the bench, Nathan liked the way he looked at his arms even more.

Not disgust.

Want.

They met again the next day.

And the day after that.

Soon it became routine. Nathan worked out in the afternoons because his body craved it, and Dave inevitably found him there. Sometimes he spotted from behind, his hands almost embarrassed by how little help Nathan needed. Sometimes he asked questions about muscle fibres, protein synthesis, androgen receptors, myostatin pathways. Nathan answered when he could. More and more often, he lost track midway through.

Then Dave would laugh and say, “It’s okay, big guy, I got the idea.”

Big guy.

Nathan should have hated that.

Instead it warmed something low and hungry in him.

Dave never mocked him. Not once. If anything, he admired the new Nathan more than the old one probably would have believed possible. He asked to feel his arm. He watched him train with open amazement. He listened, wide-eyed, when Nathan started talking about the serum.

At first he only meant to brag.

“There’s more of it,” Nathan said one evening, after the two of them had drifted from the gym to a dark wooden pub just off campus. They stood at the bar with pints in hand, shoulders almost touching. Dave wore a fitted burgundy polo that made him look even smaller beside Nathan’s dense, sleeveless grey training shirt.

Dave blinked. “More of what?”

“The stuff. The serum.” Nathan lowered his voice and grinned in a way that was meant to be conspiratorial but came out broad and obvious. “The stuff that makes people big.”

Dave stared at him. Then he laughed.

“You’re serious.”

Nathan took a swallow of beer and nodded. “Purple ampoules. Locked in cold storage. My old lab.”

The laughter faded from Dave’s face.

“You still have access?”

Nathan tapped the pocket where his old security badge still sat. The administration had meant to revoke it, probably. Or maybe they had forgotten. Lately, lots of people forgot things around Nathan. He had a way of filling a room that made ordinary details disappear.

Dave leaned in.

“You mean that stuff is real. Like… actually real.”

Nathan grinned again, drunk now on beer and attention and the simple thrill of being the man with the secret. “Told you. Makes people BIG.”

Dave looked down at his own narrow forearm. The smile he gave Nathan this time was smaller, more private, more dangerous.

“What else does it do?”

Nathan hesitated.

He remembered rage. Pain. His own hair falling into the sink. The graph lines on the screen. Priya’s face. The number 92.

But the memory was fuzzy around the edges, stripped of context. It no longer felt like a warning. It felt like something unfortunate that had happened a while ago.

“Makes you kinda… different,” he said at last.

“How different?”

Nathan searched for the precise answer and found only a shrug.

“Less in your head. More in your body.” He flexed one arm unconsciously, enjoying the way Dave’s eyes followed the movement. “Feels pretty good, honestly.”

Dave drank the rest of his beer.

By the time they left the pub, the decision had almost made itself.

The biochemistry building was nearly empty at night.

Nathan knew the route by instinct even when the names of rooms eluded him. He led Dave down the dim corridor, broad shoulders stretching the ragged armholes of his gym shirt, his soft grey sweatpants hanging low on his massive hips. Dave followed close beside him, heart pounding visibly in the hollow of his throat.

The frosted glass door still read BIOCHEMISTRY LAB – RESTRICTED ACCESS.

Nathan swiped the badge.

The light turned green.

Dave laughed under his breath in disbelief. “No way.”

The lab smelled faintly of disinfectant and cold metal. Computer monitors glowed in sleep mode. Racks of glassware and microscopes sat in the blue-white gloom. Nathan headed straight to refrigeration, as if his body remembered what his mind had lost.

Inside, in a locked tray he opened with shaking fingers, a dozen ampoules shimmered with a vivid violet light.

Dave stared at them as if they were holy relics.

“Oh my God.”

Nathan took one tray. Dave took another. They looked at each other across the bench, both breathing faster.

“Take ’em,” Nathan said.

That was the moment the last sensible version of either of them might still have stopped.

Instead, they stole the future in neat little rows of glowing purple glass.

Dave’s dorm room was cramped, poster-covered and untidy in the way bright young men often lived when they assumed they would have time to organize their lives later. There were notes pinned to cork boards, stacks of textbooks, half-drunk coffee mugs, a laptop open to a dense article about developmental signalling.

Nathan glanced at the screen and understood almost none of it.

Dave set the tray down on the table.

He picked up one ampoule, turning it between slim fingers. Purple light played across his face.

“You really did this,” he whispered.

Nathan stood opposite him, both hands braced on the wood. “You wanna be big or not?”

Dave looked up.

There was fear in him, yes. But there was also a hunger Nathan recognized immediately. The hunger to stop being overlooked. To stop being the smartest boy in the room and start being the one people desired without needing explanation.

Dave cracked the ampoule.

“Okay,” he said, with the breathless excitement of someone stepping off a cliff on purpose. “Okay. Let’s do it.”

He swallowed.

For three seconds, nothing happened.

Then Dave doubled over so hard the empty ampoule fell from his hand and shattered on the floor.

“Jesus—”

His whole body seized. He clutched at his stomach, knocking into the couch. Nathan moved toward him, but too late. Dave pitched sideways onto the cushions, gasping through clenched teeth.

“Hurts,” he hissed.

Nathan’s pulse quickened—not with alarm, but with anticipation. He remembered this part. The pressure. The swelling. The sudden terrifying rush of becoming more.

Dave’s arms tightened first. The lean definition beneath his sleeveless top thickened visibly, biceps rising, shoulders rounding outward. Seams stretched. Veins appeared along his forearms.

He looked at them, eyes wide.

“Oh—oh my God.”

His chest expanded beneath the burgundy fabric. Pectorals swelled full and high, forcing the shirt tight across a torso that had been athletic but modest moments before. His thighs spread under the denim. His neck thickened. The couch creaked beneath the sudden increase in his weight.

Dave tried to say something technical—Nathan could see it in the shape of his mouth, the instinct to classify, explain, theorize—but the sentence died halfway out.

“My… my… uh…”

Nathan smiled.

“Yeah,” he murmured. “Gets hard to think.”

Dave’s eyes snapped to his. For an instant, panic flared. He understood then. Not fully, not scientifically, but enough. His clever face twisted as he grabbed the edge of the table.

“What did you—”

Pain cut him off again.

His arms ballooned faster now, filling the sleeves until the seams snapped with soft popping sounds. Muscle rolled over muscle, round and dense, absurdly fast. His forearms thickened until veins laced over them like blue cords. The burgundy polo clung to a chest that had become broad, solid and powerful. His face changed more slowly but no less surely: jaw thickening, brow heavier, cheeks roughening with stress and blood flow.

Dave moaned and gripped his head.

“Nathan, I—I can’t…”

“You’re okay,” Nathan said, though the grin on his face made the words almost obscene. “You’re getting BIG.”

Dave breathed hard through flared nostrils. His body was still growing, but the panic in his expression was already starting to lose shape, becoming simpler. His eyes darted toward the papers on his desk as if trying to anchor himself to the person who had read them.

He looked at the laptop.

Looked at the notes pinned to the wall.

Looked back at his own massive forearms.

Then, slowly, wonder overtook fear.

“Ohhh,” he said.

The sound was almost stupid.

Nathan loved it instantly.

Dave sat hunched on the couch, one huge hand spread over his abdomen, the other flexing experimentally in front of his face. He laughed once—short, disbelieving—then again, lower and fuller. When he stood up, the jeans pulled tight over legs that had thickened almost beyond recognition.

Nathan stepped close.

Dave did not back away.

“You okay?” Nathan asked.

Dave blinked. His thoughts were visibly slower now. Still there, but softened, simplified, drifting toward sensation instead of analysis.

“Feel…” He swallowed, then broke into a broad, dazed smile. “Feel huge.”

Nathan laughed.

“Yeah, buddy. You are.”

Dave looked him up and down with new eyes, no longer just admiring but recognizing. Like seeing the shape of his own future standing in front of him.

“You big too,” he said.

The sentence was childish.

So was the warmth that flooded Nathan’s chest.

By the following evening, Dave’s transformation had settled into its new equilibrium.

The posters on his wall now seemed like decorations in a room that no longer belonged to the man who had hung them. He and Nathan sat side by side on the couch, the empty tray of ampoules on the coffee table beside a dead tablet neither of them had bothered to turn on.

Dave held his stomach with both thickening hands, occasionally wincing when another tightening ripple passed through his torso. Each time, Nathan only smiled at him, patient and proud.

“Still hurts?” Nathan asked.

“A little.” Dave looked over, frowning with the effort of thought. “But good hurt.”

“Yeah.”

Dave’s face had grown rougher overnight, older somehow, while his body kept gaining dense, exaggerated mass. His forearms were now nearly as thick as Nathan’s had been a week ago. His sleeves strained. His neck had thickened. Even his expression seemed broader, simpler, easier to read.

He had tried, once, to explain what he thought the serum was doing to his cognition.

He had gotten as far as, “My brain’s kinda…” and then given up with a sheepish grin.

Now he mostly flexed and smiled and leaned too close when Nathan talked.

It should have horrified Nathan.

Instead he felt less alone than he had since the moment H-17 entered his bloodstream.

Dave turned to him.

“You knew,” he said softly.

Nathan shrugged.

“Kinda.”

“You still gave it to me.”

Nathan met his gaze.

There was accusation in the words, but not enough intelligence left behind them to harden into resentment. Mostly there was curiosity. And a strange, grateful affection.

Nathan’s smile spread slowly.

“You wanted it.”

Dave looked down at his hands. At his swollen forearms. At the tight pull of his shirt across a chest that kept pressing outward against the buttons.

Then he smiled too.

“Yeah,” he admitted. “I really did.”

Silence settled around them, warm and dim. Outside the dorm window, the campus lights glowed against the night. Inside, the room felt smaller than ever with both of them in it—two broad, overgrown bodies crowding the couch, one born from ambition, the other from temptation.

Nathan lifted a hand and rested it against Dave’s thick shoulder.

Dave shivered.

Then he leaned in and kissed him.

It was not graceful. It was hungry, clumsy, blunt with need and relief and the stupid animal satisfaction of finding someone who now made sense in the same reduced, physical way the world did. Nathan kissed him back immediately, one huge hand closing around the back of Dave’s neck.

When they finally broke apart, both were smiling.

“Big boys,” Dave said, almost reverently.

Nathan laughed so hard his chest shook.

“Yeah,” he said. “Big boys.”

On the table in front of them, one ampoule remained unbroken at the bottom of the metal tray, still glowing faintly violet in the half-light.

Neither of them noticed it.

Or maybe neither of them cared.

Nathan found the last ampoule beneath the metal tray the following morning.

He held it up between two thick fingers, turning it toward the dorm-room window. Violet light slipped across his bald scalp and the heavy ridges of his face. Across the room, Dave sat on the edge of the bed, shirtless, admiring the new mass packed across his chest.

“Thought we drank all of ’em,” Dave said.

Nathan frowned at the ampoule.

For several seconds, neither man remembered why they had stolen so many in the first place.

Then Dave smiled.

“We could make another guy big.”

Nathan’s face brightened instantly.

“Yeah.”

The idea was simple enough for both of them to hold on to.

One ampoule. One more transformation. One more man brought into their new world of thick arms, heavy bodies and easy thoughts.

But as Nathan continued staring at the glowing fluid, something larger began assembling inside his damaged mind. It was not a scientific plan. He could no longer calculate concentrations or predict metabolic saturation. The formulas that had once made him brilliant had become inaccessible symbols, like writing from a lost civilization.

Yet one instinct remained.

Dilution.

Nathan remembered that word.

“You put stuff in water,” he said slowly, “and it spreads.”

Dave looked up from flexing his bicep.

“Spreads?”

“Yeah. Like… everywhere.”

Nathan’s grin widened.

Dave’s expression changed as understanding—blunt, incomplete understanding—reached him.

“Everybody drinks water.”

“Everybody.”

For a moment they sat in silence, looking at each other.

The university had called Nathan dangerous. The scientists had stared at him as though his new body were a disease. Students had whispered when he passed. Administrators had erased his name from the laboratory doors before they had even finished examining him.

They all thought the transformation had ruined him.

Nathan no longer agreed.

He was stronger than any of them. Bigger than any of them. He no longer spent sleepless nights worrying over grants, publications or professional rivalries. He ate when he was hungry. Lifted when he felt restless. Slept when he was tired. Dave kissed him and looked at him as though he were the most important man alive.

Life had become wonderfully manageable.

Why should they keep that gift to themselves?

“We make the whole place big,” Dave whispered.

Nathan closed his fist around the ampoule carefully.

“Big campus.”

Dave laughed.

“Big guys.”

They kissed beneath the violet glow, delighted by the generosity of what they were about to do.

Neither of them considered that the serum had never been designed for dilution.

Neither remembered that Nathan’s original injection had contained only a fraction of an ampoule.

And neither understood that the unopened trays they had stolen from the laboratory were not all identical.

Some had been concentrated experimental stock.

The university’s oldest service tunnels ran beneath the science buildings.

Nathan remembered them only in disconnected flashes: pipes, concrete stairs, warning signs and the constant metallic thunder of machinery. Dave knew slightly more because he had once helped catalogue water samples for an environmental chemistry project.

Together, that made them just competent enough to cause a catastrophe.

They entered after midnight.

Nathan wore his torn grey training shirt and sweatpants. Dave had forced himself into the burgundy polo, though its sleeves now cut into his arms and several buttons had already popped loose. They moved through the tunnels carrying the trays, laughing whenever their shoulders bumped against doorframes.

At the end of a maintenance corridor stood the university’s main potable-water reservoir.

The great metal tank rose into darkness beneath a buzzing fluorescent lamp. Yellow letters stretched across its curved surface:

POTABLE WATER

Dave sounded the words out.

“Pot… able.”

“Means drinking,” Nathan said confidently.

“Oh.”

They sat together on a low concrete barrier in front of it, surrounded by pipes and condensation. Nathan held up an ampoule. Violet light illuminated both their faces.

“This is gonna help everybody,” Dave said.

Nathan wrapped one arm around him.

“No more skinny guys.”

“No more nerds.”

Nathan laughed. “No more smart people looking at us funny.”

That sentence settled something between them.

Dave leaned against Nathan’s enormous shoulder. Nathan kissed the top of his head.

Then they emptied the serum into the university water supply.

Not one ampoule.

All of them.

The concentrated violet solution disappeared into the reservoir without changing its colour. Within minutes, pumps carried it outward through kilometres of pipework: into laboratories, dormitories, lecture halls, cafeterias, fountains and gymnasiums.

Nathan and Dave watched the machinery vibrate.

“Gift’s moving,” Dave said.

Nathan nodded solemnly.

“Everybody gets big.”

They remained there for nearly an hour, holding each other and smiling at the tank.

Above them, the first morning taps began to open.

Connor Vale had been awake for twenty-seven hours.

He was a doctoral candidate in computational molecular biology, though he corrected anyone who called him a student. At twenty-six, he had already published four papers, presented at three international conferences and developed a protein-folding model his supervisor privately believed might become the foundation of his career.

Connor lived on caffeine, resentment and the certainty that almost everyone around him was wasting his time.

He had black, disordered hair, several silver earrings and a habit of wearing the same graffiti-covered denim jacket for days. At seven fifteen that morning, he left the graduate computer room with a headache pulsing behind his eyes and walked toward the nearest drinking fountain.

He did not notice anything unusual about the water.

It was clear.

Cold.

Perhaps slightly metallic, but the pipes in the old building had always tasted that way.

Connor drank deeply.

Then he returned to his office.

The first cramp struck before he reached the courtyard.

He stopped beneath the trees and pressed one hand against his stomach. The pain felt less like illness than pressure—something expanding violently beneath his ribs.

Connor bent forward.

“Christ…”

A second wave passed through him.

His knees buckled.

He caught himself against a brick wall, breathing hard. Students moved around him, some slowing to look. Connor tried to wave them away, but his fingers had begun to tremble.

Then the sleeves of his jacket tightened.

Connor stared down.

His forearms were changing.

Muscle thickened beneath the fabric in smooth, visible surges. His wrists widened. Veins pushed against pale skin. The jacket’s cuffs bit into him so sharply that he tore them open with strength he had not possessed thirty seconds earlier.

“What the hell?”

His voice came out deeper.

Connor stumbled into the open courtyard, clutching his abdomen. His shoulders rolled outward beneath the jacket. The seams groaned. His chest filled the shirt underneath, stretching the faded logo until it distorted.

Several students stopped walking.

A phone appeared.

Then another.

Connor tried to tell them to call the medical centre.

“Get—get a—”

The word vanished.

Not from his tongue.

From his mind.

He knew there was a place with doctors nearby. He had worked there. Passed it every day. The name should have been obvious.

But there was only a blank space where the word belonged.

His jacket split across the back.

Connor cried out as his shoulders expanded violently, broadening beyond any natural proportion. Both sleeves ripped along the seams. Dense muscle poured into his upper arms, swelling them until they hung away from his torso.

He fell to his knees.

The discarded jacket slid from his body and landed behind him.

His T-shirt clung to a torso that had become thick, powerful and rapidly larger. Each breath inflated his chest further. His neck widened. Trapezius muscles rose beside it, pushing upward until his head looked small between them.

Connor reached for his phone.

He could not remember the passcode.

Four numbers.

He had entered them hundreds of times.

Now they meant nothing.

“Come on,” he whispered. “Come on, think.”

His thumb hovered over the screen.

He tried his birthday.

Forgot the year.

Tried his office number.

Forgot which building he worked in.

His doctoral research surfaced as a collection of isolated images: proteins, graphs, lines of code. He recognized them as things that had once mattered desperately to him, but he could no longer understand how they connected.

His arms continued growing.

Biceps rose into enormous rounded peaks beneath his skin. His forearms thickened into veined clubs. His hands became broad and heavy, fingers too large to operate the phone. It slipped from his grip and struck the pavement.

Connor stared at it.

“What’s… what’s that called?”

Someone in the gathering crowd laughed nervously.

Connor’s eyes filled with terror.

He understood what was happening now—not scientifically, but personally.

He was losing himself.

“No,” he said.

His chest surged again.

The T-shirt tore open at both shoulders. Fabric peeled away from swollen pectorals and hung in strips across his abdomen. His body had become grotesquely powerful, wider than the doorway behind him, every muscle exaggerated beyond athletic beauty into something engineered for pure mass.

He planted both hands on the pavement and tried to stand.

The movement launched him upright with shocking force.

Connor staggered, unbalanced by his own proportions. His massive shoulders rolled beneath shredded cloth. His thighs stretched the black jeans until the stitching popped along his hips.

People backed away.

Connor looked at their frightened faces and tried to explain.

“I’m Connor Vale. Doctor—no. I’m doing… I do…”

He rubbed his forehead.

The title was gone.

Doctoral candidate.

Researcher.

Scientist.

He knew he had been someone important.

Something beginning with a P.

Professor?

No.

Something about school.

“Student,” someone whispered from the crowd.

Connor turned toward the voice.

“Yeah,” he said gratefully. “Student.”

His face had begun changing too. The delicate sharpness vanished beneath thickening bone and swelling muscle. His jaw grew square and heavy. Stubble darkened across his cheeks. Deep lines formed around his eyes as strain, hormones and accelerated physical maturation rewrote him.

He looked older.

Harder.

Simpler.

Connor flexed his right hand.

His enormous forearm tightened.

For one flickering instant, admiration broke through the panic.

“Whoa.”

He stared at the muscle.

Then remembered he was supposed to be afraid.

“No. No, this is bad.”

But bad was becoming an increasingly complicated idea.

His thoughts now arrived one at a time. There was no longer a crowd of simultaneous considerations, no cascade of possible causes, no reflexive analysis of symptoms and mechanisms.

There was pain.

There were people staring.

His arms were huge.

He was thirsty again.

Connor’s mouth opened.

“What happen me?”

A woman in the crowd covered her mouth.

His final transformation began with a roar.

The sound burst from him as his shoulders swelled for the last time, rising into immense veined masses that tore away what remained of his shirt. His arms became nearly as large as his torso. His chest stood out in thick slabs beneath exposed skin. His thighs expanded until the jeans strained like painted fabric.

Connor dropped to his knees again, not from weakness but because his altered body no longer understood its own strength.

He pressed both hands against his stomach.

His face twisted.

“Make stop!”

The words echoed between the buildings.

No one came near him.

Connor’s mind contracted around the terror. Facts disappeared in quick, silent collapses. The names of his supervisors. The structure of a cell membrane. His apartment number. The title of his dissertation. The reason he had chosen science. The books he loved. The equations he once carried effortlessly in his head.

Gone.

Gone.

Gone.

By the time the pain receded, Connor Vale’s measured intelligence had fallen to fifty-six.

He remained kneeling in the middle of the university courtyard, a colossal mass of muscle in torn clothing, staring at the frightened strangers surrounding him.

Someone asked his name.

Connor blinked.

“Con… nor,” he said eventually.

Then he looked down at his arms and flexed them.

His expression softened into childlike amazement.

“Connor big.”

The medical team reached him eight minutes later.

They found him sitting cross-legged on the pavement, smiling whenever anyone touched his biceps. He could follow one-step instructions. He knew that he was hungry. He knew that he liked being praised. He could no longer read the identification card in his wallet.

A nurse asked whether he remembered drinking or eating anything unusual.

Connor frowned until his forehead wrinkled.

“Water.”

“From where?”

He turned and pointed toward the science building.

The nurse looked at the fountain beyond the glass doors.

At that exact moment, three students entered the corridor behind it.

One filled a bottle.

Another drank directly from the stream.

The third splashed water over his face.

Across campus, taps continued to run.

Coffee machines filled.

Cafeteria kitchens opened.

Showers poured over hundreds of bodies.

Nathan and Dave stood at the far edge of the courtyard, partially concealed beneath the trees. Their immense shoulders touched as they watched Connor being helped onto a reinforced transport trolley.

Dave grinned.

“Worked.”

Nathan nodded, his eyes shining with pride.

“Made him real big.”

Behind them, a scream rose from one of the dormitories.

Then another answered from the library.

Then several more.

Nathan slipped his thick hand into Dave’s.

Together, they listened as the gift spread.

Ron Halber got up before six every morning.

Not because he enjoyed it. Not because he possessed unusual discipline. He did it because his athletic scholarship was the only reason he was still at the university. Without football, the weight room, and the coaches who constantly reminded him how valuable his body was to the team, Ron would never have been admitted.

He was strong. Fast. Durable.

Nobody had ever accused him of being brilliant.

Ron knew that. He made jokes about it before anyone else could.

“Brains aren’t my major, bro,” he would say whenever a tutor had to explain something for the third time.

Everyone laughed, and Ron never had to admit how difficult even his easier classes were becoming.

That afternoon, he had already endured two hours of conditioning beneath the sun. His grey STATE shirt clung to his chest, his shorts were damp, and his mouth felt as though it had been packed with cotton.

He was thirsty.

Unnaturally thirsty.

Ever since waking that morning, his body had seemed to demand water faster than he could drink it. Every bottle provided relief for only a few minutes before the dryness returned.

So instead of heading back to the locker room, Ron stopped at the old stone drinking fountain near the centre of campus.

He bent over the basin and drank deeply.

The stream splashed against his mouth and ran down his chin. He swallowed again and again, barely pausing to breathe. Water soaked the front of his shirt, but he continued until his stomach felt heavy and his throat finally stopped burning.

Ron straightened and wiped his mouth with the back of one hand.

“Damn,” he muttered. “Needed that.”

The relief lasted perhaps ten seconds.

Then something twisted inside his abdomen.

Ron grunted and grabbed the edge of the fountain. The pain was not sharp. It was deep, spreading pressure, as though invisible hands had entered his body and begun pulling him apart from within.

He doubled over.

“Oh, shit.”

The pressure intensified.

His stomach cramped. His chest tightened. A feverish tingling rushed through his arms and legs, growing stronger with every beat of his heart.

This was not dehydration.

It was not food poisoning.

Something inside him was growing.

Ron staggered away from the fountain, one hand pressed against his abdomen. He crossed the path and stumbled onto a sunny patch of grass, hoping that lying down might stop the dizziness.

For several seconds, he rested with his hands behind his head and his eyes closed.

The heat inside him continued rising.

His chest throbbed.

His shoulders pulsed.

The muscles along his arms began to ache with the familiar pressure of a workout pump—except he was no longer lifting anything.

Ron opened his eyes.

His sleeves were tightening.

At first, the difference seemed small. His biceps merely looked fuller, as though he had finished a perfect set of curls. Then they swelled again.

The fabric dug into his skin.

Ron sat up sharply.

“No. No, man…”

His forearms thickened before his eyes. Veins pushed to the surface, snaking beneath taut skin. His wrists became heavier, his hands larger. At the same time, his thighs began expanding inside his shorts, the quadriceps rising into dense new curves.

Ron stared in disbelief.

“What the—”

His chest surged outward.

The grey shirt stretched tightly across his pectorals. Every breath made the fabric creak. His shoulders rolled back as new mass packed itself around the joints.

Ron tried to stand.

A violent cramp forced him back down.

“Help!”

The cry came out higher and more frightened than he intended.

Several students stopped on the path. One young woman stared. A boy farther away immediately raised his phone.

Ron lifted both hands as though he could shield himself from the changes.

“I think something’s—”

His words ended in a gasp.

His chest expanded again with a heavy internal lurch. The shirt was forced outward by slabs of muscle that had not existed seconds earlier. His shoulders widened, rounding into thick caps. The sleeves cut into his arms until the stitching began to snap.

Ron screamed.

His legs were changing even faster. His quadriceps swelled into massive, divided columns beneath the shorts. His hamstrings pushed against the fabric. The material stretched until it shone.

“Call somebody!” he yelled. “Call my—”

My what?

His coach.

Yes. He needed his coach.

But the coach’s name would not come.

Ron blinked.

He knew the man. He saw him every day. The coach shouted during practice, stood beside the field, wore the same navy cap—

But the name was gone.

So was the office number.

So was the route to the athletic building.

Ron stared ahead, suddenly more frightened by the blankness inside his mind than by the growth spreading through his body.

“I need to go to…”

He stopped.

Where?

The thought slipped away before he could finish it.

His arms continued swelling. Biceps rose into heavy, round masses. Triceps thickened behind them, pushing his elbows away from his sides. Ropes of veins travelled down his forearms.

The crowd around him grew.

“What’s happening to him?”

“Is this some kind of stunt?”

“Someone call an ambulance!”

Ron looked from face to face.

He wanted to explain. He wanted to tell them what he had done that morning, what he had eaten, how much he had drunk.

But organising the information had become difficult.

His thoughts felt slow and sticky, as though each one had to force its way through mud.

“What happened?” someone called.

Ron looked down at himself.

“M-Muscles,” he answered.

It was the only explanation he could form.

Then the next wave struck.

His deltoids ballooned outward so violently that both sleeves tore open. The shoulder seams split with a harsh ripping sound. His back broadened beneath the shirt, while his neck thickened and his trapezius muscles rose beside his head.

Ron pushed himself upright.

The ground seemed farther away than before. His legs had become pillars, packed with more muscle than any athlete could develop naturally. Enormous thighs filled his shorts. His calves swelled into hard, vascular shapes.

He raised his arms helplessly.

“Holy shit…”

For a moment, fear was replaced by awe.

He had spent years training for size and strength. He had obsessed over measurements, weight, protein and progress photographs.

Now his body was becoming everything he had ever wanted.

And far more than any human body should have been.

He flexed instinctively.

The bicep rose like a living growth beneath his skin.

Ron’s mouth fell open.

“Dude…”

Then something inside his head gave way.

He blinked and tried to remember what class he had attended that morning.

Nothing.

He searched for the name of his course.

Nothing.

He tried to count backwards from ten.

“Ten… nine… eight…”

He frowned.

What came next?

His enormous hands began to shake.

“Wait.”

He tried again.

“Ten… nine…”

The numbers refused to remain in the correct order. They drifted apart, meaningless symbols he could almost recognise but no longer hold.

Ron looked around at the gathering students, frightened and confused.

He still knew he attended the university.

But he could not remember his major.

He could not remember which building contained his dormitory.

He could not remember the surname of the roommate he had lived with for seven months.

The muscles kept growing while the knowledge disappeared.

His chest thickened. His shoulders climbed higher. His arms became grotesquely oversized, each one nearly as broad as his former torso.

The remaining fabric around his upper body tore open, exposing swollen flesh and branching veins.

Ron groaned, but the sound was becoming less articulate.

“Too… big.”

He understood those words.

Big was simple.

Big was something he could see.

The rest was becoming complicated.

A loose strand of dark hair drifted across his face.

Ron brushed it aside.

More strands followed.

He touched his scalp and pulled away a handful of hair.

“My hair!”

Dark clumps slid down his forehead and shoulders. The thick athletic haircut thinned within seconds, retreating across his scalp as though erased by an invisible flame. Hair collected around his shoes.

Ron rubbed both hands over his head.

The last stubble vanished beneath his palms.

His scalp was completely bare—smooth, tight and shining in the afternoon sun.

He stared at the hair scattered in the grass and struggled to understand that it had once belonged to him.

The transformation finally slowed.

Ron stood in the middle of the campus lawn, hairless and impossibly massive. His shoulders had swollen wider than the doorway of his dorm room. His arms hung away from his sides because the muscles no longer allowed them to rest normally. His thighs strained against shorts that had survived only because the fabric had stretched nearly to transparency.

His young face remained recognizable, but the intelligence behind it was fading.

His eyes were wide.

His mouth hung partly open.

The frightened scholarship student was still somewhere inside him, but he could no longer form thoughts complex enough to understand what he had lost.

A campus medic approached carefully.

“Can you tell me your name?”

Ron stared at her.

The answer took several seconds.

“Ron.”

“Good. Ron, do you know where you are?”

He looked at the buildings.

“School.”

“What school?”

Ron frowned deeply.

The effort made his head hurt.

“Big school.”

The medic exchanged a glance with her colleague.

“Do you know what happened to you?”

Ron looked down at his enormous chest. Then he lifted one arm and watched the bicep rise.

His fear weakened.

A slow smile spread across his face.

“Water made Ron big.”

“Did you drink from that fountain?”

Ron looked toward the stone basin.

He understood drink.

He understood water.

He nodded eagerly.

“Good water.”

“No, Ron. Don’t drink any more.”

His smile disappeared.

“Why?”

“Because it did this to you.”

Ron looked at his body again.

His grin returned.

“Big is good.”

Behind the medics, another student screamed.

A young man had collapsed beside the fountain. His back was already stretching the fabric of his jacket.

Then someone shouted from the science building.

Another scream answered from the residence hall.

The contaminated water had spread through the entire university system.

Later, the hospital would document Ron’s condition in cold clinical language. Before the exposure, his estimated IQ had already been below the university average. After ingesting an enormous concentration of the serum, his measured cognitive function had collapsed to the equivalent of an IQ of 36.

The damage was permanent.

Ron could still speak in short phrases. He recognised familiar faces. He understood food, sleep, pain, affection and exercise.

But reading was gone.

Numbers were gone.

His education, memories and ambitions had been consumed to feed the impossible body now surrounding him.

The medic tried once more.

“Ron, we need you to come with us.”

He did not move.

Instead, he raised both arms and flexed.

The muscles swelled like boulders beneath his skin.

Ron stared at them with childlike wonder.

“Ron strong.”

“Yes,” the medic said quietly. “Ron is very strong.”

He beamed.

At the edge of the lawn, Nathan and Dave watched from beneath the trees.

Both were bald now. Both were huge. Their fingers were intertwined, their thick arms pressed together as they observed the first stage of the campus-wide outbreak.

Dave leaned against Nathan’s shoulder.

“Lots of big guys soon.”

Nathan smiled.

“Whole school.”

Neither man could remember why they had once believed spreading the serum was a good idea.

They no longer possessed enough intelligence to regret it.

Behind them, the university bells began ringing.

Ron looked toward the sound, confused for a moment.

Then he forgot about it.

He flexed again and laughed.

“Ron big.”
