He definitely has used it - he's quite candid about it, in fact! - and now lives in a country where (I believe) it's legal, and is getting into competitive powerlifting. So... chances are... well, you know.
No idea if that's got anything to do with his program. FRom memory, it's Stronglifts 5x5 with some other lifts added @ 3x8 (?), basically.
Which sounds brutal but okay, if that appeals, and if you have recovery and nutrition all sorted.
edit: Oh, did you mean that other guy... haha. Oh well.
