I personally have never used it, could never find it cheap enough but 2 friends of mine used it and ran it for about a month each about 6 months ago and they both loved it. They both reported pretty surprising fat loss, striations, vascularity in the sites they shot, mostly shoulders, arms, legs. One of them reported pretty good direct site gains. He said he put on 1.6 inches on his arms in the month he was on. The other guy said he had some site growth, but nothing extremely impressive. They both only shot im. However, they did say the sides were pretty brutal.
