I believe he got shot in the eye with a bb gun as a child.
Everyone's heard "you'll shoot your eye out." Well, that actually happened to Peter. Worse things have happened for sure, but that's probably not the greatest childhood memory he has.
He's an intelligent guy with an actual set of values that can hold a normal non-bodybuilding related conversation. He is married to a beautiful woman that happens to be a figure pro.
Clearly, that is a supplement company's wet dream. People are going to dislike him for those reasons, that's the nature of the game, but I don't think you can blame him for being marketable. If you're going to make a living and feed your family, you have to make money.
