Most of the stuff I read had been written awhile ago, around 2005. I ran across some message boards saying Shawn Merriman claimed he tested positive from this as well. I don’t honestly know if its true and I doubt it can be a very common thing, but I’d rather buy my supps from some place made in America where it falls under the Anabolic Steroid Control Act and should have no reason to even possibly have cross contamination or anything like that.
