I love getting commissioned by @gigarex.bsky.social. A Mr Gay Olympia competition goes awry. One drained bodybuilder becomes 2, becomes 10, becomes-- well, you get the idea.

Coach looked up with pride as his favorite boy lurched and ERUPTED with muscle! The former pipsqueak was finally reaching his true potential. A BEAST beyond human limitations!

"Coach... it's-HNNGGG TOO MUCH! I can't stop... GETTING BIGGER!"

Piece done by the legendary @samuelbarbado.bsky.social
Commissioned artwork by Samuel Barbado Harvey reacted quickly to Coach’s new post-workout smoothie from GROtein Labs. He groaned and roared as his arm quickly outgrew the rest of his body. A massive pillar of muscle hanging down to his knee! Then his chest followed suit. His feet. Every inch of him doubled then doubled again! Tearing through his gym clothes as he surpassed them. His broad shoulders pushing against either wall of lockers, denting the metal doors with just his growth. Soon, he completely filled the locker room, cracking and destroying anything in the way. He was a monster. Coach couldn't be more proud.

"Come on, you're not just gonna stare, are you? Muscles this big deserve at least a little worship, right?"
A man wearing only unbuttoned jeans in a metal room, with smoke slightly obscuring the left side of the picture. He has his hand out, and his muscles are morphed to be incredibly exxagerrated.
