This is my knowledge on Ronnie's explosion in a few years. I was trained by a guy who trained Ronnie when he was an amateur and still doing "natural" shows. The fact is back then Ronnie didn't use much shit. My old trainer told me the amounts he had Ronnie using and it was less then people here use. The bottom line is somewhere along the road Ronnie added gh, insulin and increased the amount of shit to the same as everyone else. His superior genetics that allowed him to keep up on less shit and no gh now made him the best in the world when he did what everyone else was doing. Why do you think you never see anyone else grow as Ronnie did. It's because all of these guys are maxed out on shit already, by the time they turn pro. Their gains then come very slowly. Now you take someone who turned pro with no gh and no insulin and a minimal amount of anabolics and you have a monster waiting to happen.
By the way no one in history could beat Ronnie right now. Dorians best part was his back and I think Ronnie has him beat there also. If not beat it is a draw. The rest of their bodyparts is really not much on a contest. Forget arms as Dorians arms were really weak and Ronnies are unbelievable. The only bodypart that Dorian has him on is calves and no one wins or loses an Olympia on calf development. Symmetry is hands down Ronnie and Ronnie comes in harder. I do not see how Dorian would have a chance. As for the best genetics of all time I would say FLEX by far but he is too damn lazy.
