He looks like someone who just cycles in smaller doses. I've seen some crazy pics where he looks like he has way too much size, but then contest shots and dieted shots he looks a bit smaller.
If I weren't so lazy I'd find the crazy shots, but they're out there. Either way, he looks fantastic and doesn't show up on stage in the third trimester with a distended gut. I don't give a shit about drug use, but I think it's nice when guys don't go overboard.
