I call bullshit on 100iu GH/day. Ronnie couldn't afford food, let alone drugs, when he first finished college, yet had a very respectable physique. The guy is not your average gym rat. I personally know natties who could compete at the state level and not get blown off the stage. Am I saying guys like Ronnie didn't megadose (especially 03 Ronnie), no, absolutely not. Chad probably had Ronnie pumping shit like no tomorrow for that Mr. O. But 100iu growth? C'mon.
Ronnie, Jay, Cormier, Wheeler, Levrone, etc... have amazing response to gear and training. These guys can take half the shit an average gym rat takes and step on the O stage. There's a reason there is only 1 Ronnie out there and not 1000 of them running around every gym. If it was "just take more drugs" then nothing would stop anyone from becoming Mr. O, or at least LOOK like Mr. O.
Have you seen Levrone lately? You really think he's running 10g of gear and even close to 100iu of gh? The guy is a lean 250 right now, and if I had to guess is running nothing close to what he ran when he was competing at the O (ie, under 2g gear, and maybe 10iu gh IF THAT, and that's on the high side I would think).
