^ of course he used and uses! lol
its a case of both, he does have great genetics but you're not getting to 250 at 10% bf or under without gear.
no genetics in the world will allow for that!
where he shines though is his genetic shape, some of the best arms and delts around - including most ifbb pro's.
weak chest, back but in wrestling it really doesn't matter.
he built most of his mass during his time competing in bodybuilding, after that its been mostly maintenance and refinement.
you can see over the years he hasn't grown but his musculature has gotten denser and denser.
likely has a script thanks to good ole' Vince for doctor prescribed gh and test, oh and nandrolone for the joints!
im guessing the doc is pretty generous with it too!
