I used to train at the gym where Doug trains. He is one of the most disciplined, focused people I've ever seen in the gym. He and his wife never miss workouts. He has incredible genetics. If you saw him you'd see TINY jounts and very full muscle bellies. Kinda like a white black dude!
Anyway, I've never followed him 24 hrs a day, but I've known plenty of guys on gear, and I'm comfortable believing him. I've also known a couple of genetic freaks... He's one.
