I want to think he's in the top bracket of fucking phenomenal naturals... but then the more I read about his diet I started to think he's on a low dose of gear. I don't think it's anything insane. But he is on a very low fat diet year round. Cholesterol is a precursor to testosterone and I can't believe that someone dieting that religiously all year (this is an off season picture, for him this is almost "fat") there's no way he's doing this clean.
Either way, I don't think he's on a myriad of drugs. I think he's on a therapeutic or slightly supraphysiological level of test, no other androgens. He definitely has his diet in check and knows his body inside and out. I wish I had the dedication to eat and drink as meticulously as him. He knows his body so well. Very intuitive.
