i also compete in a.d.a.u.(anti-drug ahtletes united). they are a raw powerlifting sanction. drug test every lifter, every meet. i was top 3 in Pa for 2005/2006, and top top 5 in 2007 in bench deadlift. that is with a 450 bench, and 625 deadlift.
i understand the shirts not being liked by some people, but everyone wears them at the meet, and they are legal. they have assisted(bench shirts), and raw contests. i do both. i actually have a better raw bench then shirted bench, most guys i go against are in the low-mid 800lbs. for bench.
