Nerdy kid in the lab, trying to cook up some hardcore muscle roids for himself, and instead he brews this cursed miracle juice that does absolutely nothing for biceps but turns asses and tits into walking gravity problems. That is the whole brain of this game: one stupid mistake, and suddenly every girl around him is at risk of waking up with a shelf for an ass and boobs that need their own chair. The story plays it kind of straight at first, like some awkward teen science project, full of test tubes, spreadsheets, and him mumbling about formulas while obviously just thinking about tits anyway. It feels almost innocent in the first minutes. Then he actually uses the stuff, and the tone just slides into pure horny chaos in slow motion.

What I liked is how casual the first growth is. No big magic spell, no “behold my power” anime pose. More like, "uh, try this sample, it might help your gains", and a girl drinks it without reading any label, like regular preworkout. She walks off, and nothing happens. You keep clicking through dialog, nothing, nothing, more nerd talk, then you get this CG where she turns sideways and you realize her leggings are fighting for their life. Ass suddenly big enough to bounce a coin across the room, but her brain didn't catch up yet. There is this really fun delay where she is still talking normal while the camera keeps sliding a bit lower, and then you see the fabric stretching and you get that tiny panic in your chest, like, "oh shit, how far is this gonna go?" Boobs follow in some later scenes, and they do not grow cute or modest. They blow up with that heavy look, like they hurt her back, which makes it even hotter because the game leans into the weight. You see straps digging into skin, tops threatening to snap. Sometimes the growth is in stages, sometimes it just jumps a couple sizes between CGs. Feels inconsistent, but in a way where you keep clicking because maybe this next one will be the really huge jump. And sometimes it is. Sometimes the juice hits like a truck.

The nerd himself is funny and pathetic at the same time. He keeps pretending he wants to “fix the formula” but also never stops “testing” it on girls who really should ask more questions. Dialogue is a bit clumsy in spots, which weirdly fits, because he talks like someone who spends more time on Discord than outside. There is this one scene where a girl sits down and her ass literally does not fit inside the frame right, like it spills out of the camera angle. You only see part of her, and it is almost annoying, because you want the full picture, but also that cropped feeling makes it seem even bigger in your head. I got stuck mentally on that one for longer than I should. Scrolled back to it from the history a few times, like "yeah, this is the good one." The game likes to tease with clothes that are one second away from surrender. Buttons strained, yoga pants shiny and stretched thin, tops that obviously were not bought for these new sizes. It is less about clothes exploding off and more about that slow, “I can’t button this anymore” humiliation. It could use more variety in body types, honestly, everything is on the big scale after a while, you start missing the contrast. But if you are in the mood to watch normal girls turn into walking boob and ass monuments thanks to one idiot with a chemistry set and zero ethics, this thing goes all in on that fantasy and never pretends to be anything else.
