I believe he is clean. Look at the other guys who were his size or bigger who probably had better lifts than him but juts was not published: Shaq(Orlando days), David Robinson, Karl Malone, Kevin Willis, and Alonzo Morning. About a month ago when I started training like that I was at 20 reps at 225. I am not saying that they are or are not on steroids. I am just saying Dwight Howards build and strength can be obtained without gear. All they have to do is train and eat for a living.
