Well, they probably don't use for quite some time as they get pretty close to the contest, so they rationalize and believe that they're therefore natural bodybuilders. I'm sure in the off-season, most of them use anabolics. Although, I will say that some of those guys looked pretty small.
I liked what Titus had to say about the guys that go the natural route. He said that he doesn't put them down for being natural, but they better not put him down for not being natural.
