That tank top is so tight after his growth, the only way he’s getting it off is if he’s cut out of it!

He has quite literally burst out of that shirt, nothing could contain those gigantic muscular lats or those huge arms!

Bless this giant muscle himbo. He’s making a valiant effort to get his vest off, but I’m afraid that as far as he’s going to get. He’s totally immobilised by his ginormous biceps.

He’s not walking anywhere quickly with those legs, and he can’t fit through any doors in the lab building. But he is stuck in the gym, so I guess he can just keep on growing…

He can barely walk with that enormous package between those bulky muscular thighs. Guess he’ll just have to stay right there…

Those extra large briefs seem to be doing a good job, for now… Just don’t turn him on!

This gigantic mountain of muscle needs assistance with the 8000 calories he needs daily. Do you think you could sustain him?

Do you think you could help spot him for a squat? Or will you be too distracted?

He squares up to you on the gym floor, towering above you, his bulging briefs are at your eye level. Could you take him?

Just a huge muscle freak casually posing in the lab. I think that’s 15 abs… I’m not sure if that enough…

He’s fresh out the growth chamber and is bulging from everywhere. All of it is much more than a handful…

Feel that immense pump in that bicep so big you can rest your hand on top.

He just can’t stop drinking down that growth serum… Want to see him as a huge muscle ball revealing everything?…

Virtually everything is ripping under the pressure of all that growth. Just a few more reps in the gym and there’ll be none of that clothing left but shreds!

He’d better hold on tight to those briefs, well, until you get there.

He’s got that look in his eyes… He wants to rip the clothes off you and satisfy you like you’ve never been satisfied before.

Sure he’s huge, but I think he can be a lot bigger…
You can see him after another overdose of growth formula over on my ₽atrėōn!

Either this meathead has been pumping himself full of roids, or he’s been pumped full with another guy’s load. Roidgut or cumgut… or maybe both?

His enormous traps are so gigantically muscular they’re crushing his head! He has to be careful flexing in case he causes himself a severe injury!

He may not be the biggest, but he is absolutely stacked solid with muscle. He can’t wait to show you all of it, inch by inch.

Would you be able to scrub his back? He literally can’t reach.

You hear the rumble of his steps first, then you see this gigantic mountain of muscle coming towards you. After all that growth he’s filled to bursting and needs to release, and you’d better oblige!

He may not be the biggest, but I don’t think I can let this one leave the lab…

He can still raise his arms, and flex his biceps, so I’m not sure he‘s quite big enough. I’d get him to use those arms whilst he still can though 😈

He sees you checking him out, every inch of that enormous mountain of muscle. Maybe you should help him give it all a test drive...

He’s trying to squeeze every last drop of growth formula into those absolutely gigantic muscles. Trying to make himself even bigger!

This guy rolled up his vest before a chest workout, only now it’s not going anywhere. Especially because his arms can’t reach. I think he should just stay like this. Looks like that pouch is about to burst open too 😈

It’s good… but if I just alter his DNA and pump him full of roids, and…
Ffuuuuuuuuuuck *BWWWOPHHHH*

He is bursting out of the (relatively) tiny singlet. All of those enormous muscles bulging and that singlet straining…

Nobody can get past my new security guard. They can barely fit, but also nobody can even resist him to pass!

When you only just get your t-shirt off with a post-workout pump… and it’s one hell of a pump. He could jerk you off with his abs, let alone his massive vascular striated pecs. What would you do with him?

How many abs is too many abs? Not to mention, his biceps bigger than his waist…

Looks like one of the lab techs decided to help himself to some of the growth formula. I think he’s going to have to be taught a lesson.

There doesn’t seem to be much left of his clothes after all that growth, well, maybe just enough to keep him modest 😂

He’s the biggest guy in the gym, but he still insists on making his triceps even bigger. Who am I to stop him?

This guy’s looking pretty pleased with the superhuman pump on his bicep. But I think he’ll be a lot more spectacular with another pump full of growth formula… You can access the even bigger NSFW image on my ₽ātrēōn! That growth formula really has a massive effect on libido 😈

This guy has just had a growth cycle on his upper body. But should he have a second cycle on his lower body, or stay a massive disproportioned muscle monster?

Not only does this guy have an enormously wide full torso, he’s also got an extremely tightly filled package just waiting to give way…

I don’t think I’d be able to take my eyes off my biceps if they were that big. And with those enormous lats, he might not be able to put his arms down…

He’s nearly a complete ball of muscle… I think one more dose should just about do it…

The growth serum is still pumping through his throbbing veins… Maybe this means his growth isn’t quite finished. He looks like he wants some more…

This gigantic beast is squatting down so his crotch is at your eye height. You’d better call him Daddy and make sure you do what you’re told!

He’s ready and waiting to serve you. What can he do for you?

It’s generally not advised to wear restrictive clothing when consuming growth formula… If you want to wear it again…

You can tell, just by that look in his eye, that he is going to absolutely destroy you. Do you think you could handle it?

This guy is seriously thick and ready to burst. But after with the growth formula still pumping around his veins, just a slight workout could have explosive results. See his final enormous form, revealing everything, over on my ₽atrėon!

Everything is incredibly full, and tight. Whether it‘s those throbbing veins pressing out under his tight skin, or those briefs straining to hold back that enormous weight...

Sure he’s big, but he looks like he can still walk. He needs another dose to ensure he’s a gigantic immobile muscle monster!

Spreading his lats to their gigantic full width, not that he can lower his arms by much…
