I think steroids builds MM in some folks.
It raises the floor for most folks. At some points, at least to me genetics takes hold. Ric Flair has been very open about it. Had he devoted himself fully to it, probably wouldbe looked like UW, who competed.
Having read Arnold's memoirs, I mean. He knew early on what his goals were. Nothing would stand between he and that. Look at Lou Ferigno compared to AS. Its apples and oranges. The dedication, type A gusto, ego, and sheer attention to detail as well as an iron clad regimin got Arnold the nod. Hell even arnold admited Lou was a genetic freak.
Gaining 15-20 lbs in a professional, yes pro type environ at UT should achievable for most folks who put in the work.
Getting folks over that hump earlier, is what anabolic steroids does. IMO.
