You guys really think these guys take in excess of those amounts? Half these guys are genetic freaks as it is, I'd assume they don't take unreal dosages. They'd be high, no doubt, but not 5 grams of test >.>
Top pros have absurd genetics as it is and that's what gets them there in the first place. Kevin Levrone, ik he's not a strongman but it's just an example, said himself he was only on 1/2 the year like the old school guy and his stack pre contest looks something like 600mg test, 600mg deca, some winstrol, and novladex. There might have been one more low dosed oral in there... Idk why he'd lie so I believe him and that's not an unreal dosage. And then there are nobodies like Boston Loyde who are on insane amounts and think they are "healthy."
tl;dr professional/top guys already have the genetics very, very few have so they don't need extreme amounts of drugs
