as dude above said, he clearly is not natural...regardless of great genetics, at his age (and when he started lifiting) he does not have near enough testosterone to maintain that degree of definition/musculature/size...Granted, lifiting heavy weights and regular exercise augments the production of testosterone, but that is a more shorter lived effect. For his baseline production, he is probably taking testosterone, whether direct replacement, or taking supplements to augment testosterone production. May be on additional supps, but testosterone is the key here.
