Are these pics from the same contest as this video? The conditioning looks about the same and, apparently, he won the contest. Is the Team U supposed to be natural?
The open class is supposed to be drug tested, but I think they only test the overall winner because he's qualified for Worlds (where they also drug test). The masters and I THINK women's classes aren't tested.
However, Phil Viz said one time he knew one of the guys competing in the open class and knows for a fact that he's used gear. I guess if you're smart about it and cut the gear out early enough, and stick to fast esters, you could get away with it without a problem.
