Yea I could definitely see adderall being used, I'm sure not on match days but for cutting up to the day before for sure. Shit even back in high school my coach gave me a script diuretic for states as a last resort, mind you by then I didn't have shit to piss out but it did the trick, also lots of ephedra while it was still easy to get a hold of I used to load up on ultimate orange before matches and wanted to almost cry when I got to my last scoop in early college. But that stuff isn't AAS and doesn't do what AAS does.
Maybe a heavyweight where making weight isn't much of an issue could load up on whatever he wanted but I can't see our little guys having been using anything nobody ever mentioned it that's for sure, they never would have made weight and that's without even taking into account how it would mess with your stamina. This might be way off but a lot of the olympic wrestlers I hung around back in the day weren't cutting weight like we did in college, hell even back in high school. Maybe something to do with your body being mature at that age so it's not like it has much to give, could be way off on that though.
