The vest is gigantic, but it still won’t even remotely cover his pecs.

His compression top is now only covering his chest and his compression shorts are barely covering his legs.

He’s not seen you around the lab before, maybe you should go on a tour of every part of him?

He’s ready for a cool down after all that pumping. Do you think you could help him out?

He’s working on growing that gut, but he definitely needs a feeder. Any volunteers?

His forearms look like they might be even bigger than his biceps, and they’re bigger than bowling balls!

He has a gigantic pec shelf and a butt shelf. You could practically climb up him. He turns and looks at you over his rippling shoulder. “Enjoying the view?”

He’s almost completely outgrown his old clothes. Looks like he had to release the pressure in his jeans though. That top looks filled to bursting point!

One of our huge hyper muscle creations is showing off his newfound size. But he’d better be careful, it might be a little too much for him!

As he flexed his biceps doubled and popped into double-headed biceps. He wanted them even bigger so he flexed as hard as he could, so hard he was pushing his fists into his rock solid biceps!

Are you going to take them off or is he going to have to struggle himself?

Even the absolutely biggest compression top isn’t big enough to contain his immense torso. Still, it’s making his veins pop!

He could feel his pants being pulled down by some immense weight, but his pecs were completely obstructing his view down. All he could do was hold on as he waddled through the lab.

He flexed his gigantic muscles and squeezed as hard as he can Bwompff another pair of abs popped up. He squeezed even harder Bwompff another pair of abs appeared and his abdomen grew slightly taller. How many could he grow? He squeezed even harder…

He wants to lick it so bad, but he’s just doesn’t have the mobility left in his arms. Maybe if his biceps were bigger…

Going out into the pumpkin fields with a full moon possibly wasn’t the best idea for Jack. Looks like the transformation has done him some good though. How about you go meet in him the hay loft?

New Hyper Muscle Growth Animation! Bane is back and he’s growing bigger than ever! His team of henchmen won’t be able to control themselves…

Venom has found one of our growth subjects. Looks like they’re both enjoying the feeling of being assimilated together. How big do you think Venom will grow once they’re one?

His robe is in shreds after all that muscle growth. Would you mind if he was calling from inside your house?

Having such a gigantic torso supported by such a tiny waist requires such incredible abs of steel. He’s got enough of them…

He kept stretching at his briefs, but he’d better be careful, they could rip open at any moment.

It’s impossible to tell where his lats end and his arms begin. Either way, he’s not going to be able to move his arms very much…

He found a vest which fits, but it doesn’t really cover up very much. Still looks a little tight around those abs though.

He’s looking pretty pumped. But there’s something which definitely still needs pumping up. Do you think you could help him?

After his growth, he still seems to have a bit of mobility in his arms. His biceps are not obstructing him enough. Do you think he needs more growth?

Stood in the gym in his wrestling gear he looks at you. Are you ready to get crushed under all that muscle?

As he sat on the bench in the lab, he wondered whether if he kept squeezing, he could add another peak to his biceps. A double peak wasn’t enough!

After the latest round of muscle growth formula, he had to test just how well his nipples worked.

How would you like to rub his bloated vascular belly? Or any other part of him?

At the bodybuilding competition, @klinear.bsky.social decided to take an Octant Flex muscle growth pill just before going on stage. But despite his insane growth, inside the pump room he’s still not big enough! He’ll have to ignore the warnings and take more! #hypermuscle #musclegrowth #roidgut

He really didn’t know his own strength. Just when he thought he had the barbell heavy enough, it split in two! He’s going to need something much bigger to lift if he’s going to get pumped!

Those loose fit jeans are definitely not loose anymore!

Would you be the dom or the sub?

As he flexed his bicep, it grew bigger. So he squeeze it some more, and it continued to grow. He had to keep on squeezing - it just felt so good!

Feeling the power of his insane new size after all that muscle growth. Now to get pumped up even bigger!

All that’s left of his jeans is what look like the last pieces of some tiny hot pants around his waist. I’m sure he won’t mind, he’s never fitting into regular jeans ever again after all that muscle growth!

He seemed shy, peeking at you from beneath the rim of his baseball cap. Will you be nice to him?

He towers over you on the gym floor stood there in his wrestling singlet. Do you wanna wrestle?

Just one tiny towel stands between you and him.

He’s been working up a sweat in the gym. His vest now barely covers his gigantic pecs! Do you think you could help him take it off?

How would you like to bury your head deep between those gigantic pecs?!

Lying on the bench, he sits up to flex his abs, and does a double bicep flex just for you. Now, are you going to help him get up or not?

He is absolutely loaded with muscle. Do you think you could handle him?

How many abs is too many abs?

His traps are so gigantic, not only is his vision severely restricted, but he also can’t hear anyone approaching him from behind…

He sat on the end of the lab bed, it creaked under his weight. He towered over you even though he was sat. He looked you up and down and contemplated his next move…

After all that growth, he knew if he could just stimulate himself a little more, he might grow even bigger!

Lucky for us, he’s worn a see-through singlet to workout in.

He’s never getting his leather jacket back on now, but I don’t think he, or anyone else, will mind. His leather pants seem to have a lot of stretch.

He came over to you on the gym floor as you loaded up the bench press. “Need a spot?” he said as he walked straight round to behind the bar. He didn’t need to use his hands to support the bar, that huge bulge which was now right above your face would stop any weight!
