id say layne norton is natural. that's the one i know of. seriously, seriously doubt this guy.
Google Michael Lockett. Great physique but he maintains that he is natural. Ronnie Coleman used to say he did not use drugs, but after he retired, I believe he coffed up the idea that he was not natural.
I think Flex Wheeler said that if Lockett is really "Natural", then he would be the ultimate genetic freak ever. I believe Brian Buchanon was another who said he was all natural. Take a look at Max Charles videos and listen to him speak about his lifts and his diet. Unbelievable shit I tell you. Some of these guys create their own reality and completely believe in it.
