Mark was the only one in the gym that evening, pushing himself to the limit. His muscles ached, but he relished the burn, a testament to his dedication. As he paused to catch his breath, his eyes caught sight of something unusual—a peculiar bottle, nestled between the treadmills.

Curiosity piqued, Mark approached the bottle, wiping the dust away with his towel. He hesitated for a moment, but his thirst got the better of him. "What harm could a sip do?" he mused, lifting the bottle to his lips.

Mark staggered backward, knocking over a row of dumbbells. He caught a glimpse of himself in the mirrored wall and gasped. Where once stood a man, now loomed a 10-foot-tall behemoth. "What have I done?" he roared, his voice a booming echo.

Mark tried to calm his racing thoughts, focusing on the rhythmic rise and fall of his massive chest. "I need to figure this out," he resolved, his mind darting to his friends, who might know what to do.

He moved cautiously, avoiding the streets where he might draw attention. The thought of his friends’ reactions both terrified and comforted him. "They'll understand," he reassured himself, determined to seek their support.

As he approached, he took a deep breath, preparing for whatever lay ahead. "Whatever happens, I'll face it," he vowed, ready to embrace the challenges of his monstrous existence, with the hope that his friends would stand by him.
