This place is insane at times, for starters different steroids will effect the body in different ways, some will add quite a bit of bulk like deca, some add strength like halotestin, some lean gains like turinabol/anavar.
Drugs like EPO, and sarm GW 501516 will help with cardio but steroids pretty much hinder it, in an already explosive athlete steroids will obviously add more power, and also enable athletes to train and recover more.
I was going to go into way more detail about the chin etc but it's such a stupid comment I'm not going to bother.
