Before juice: skinny twerp, average haircut and face, normal clothings, not a single ounce of muscle visible at all.

After juice: Arms and forearms have more than doubled in size to meaty proportions, triceps pushing past flesh like solid rocks, delts the size of cannonballs soon to cap out of the shoulders, pecs protuding way beyond his torso and sure to stretch out any shirt he wears now.
Jock haircut, extremely revealing stringer tank, obviously to show off all that new juiced muscle, probably with some dumbass shit written on it, arrogant as hell smirk while taking one of his multiple daily selfies, because he knows he looks amazing.
Yeah, you bet he thinks it was fucking worth it. Next time you don’t even need to wonder why people hop on juice like it’s free candy.
And the best part? No fantasy or magic shit about this. Roids are the real deal.
