Why would someone do steroids for 16" arms?

I've seen high school and college students with naturally bigger arms.
-2 grams of gear for 16 inch arms.
-Piss water gains from UG deca.
-Diet is shit.
-Clueless trainee at gym.
-Bald oily head.
-Didn't clean his house...
-Dog is starving.
-Prolactin is sky high...
-will fuck himself up for a skinny fat body.
