I somehow always get the feeling that Arnold used an absolute metric shit ton of gear. He probably messed around with dbols and winnies when he was a kid but somewhere along the line he just exploded and I think it was him learned to just up the dosage to the stratosphere. I mean most guys his size and condition use growth hormone and not in small doses either. He has to have an incredible response to high doses thats the only thing I can imagine that got him that big.
