I am not saying he didn't use everything and the kitchen sink in his career. But I remember when he was a NOBODY. Actually, at one point I had an online supplement company in the late 1990's and I used to have a regular customer, a woman, who worked out at a gym with Ronnie and knew him. We were talking once and she mentioned knowing him pretty well and at that time I thought, "Cool." and didn't think much of it because he didn't even really get noticed at the Olympia. He was basically a nobody. A couple years before, in 1994 - he looked was more aesthetic than he was big. No gut at all. Fast forward to 1998 and he's taking it all. Crazy change. I never saw it coming. Obviously between then he hit everything he could haha.
But prior to that, he claims he went pro without using drugs. I don't necessarily believe it, but...I think the point is that those guys have crazy genes and can do more without drugs than a lot of us do with drugs.
