yeah ive tried it. I stacked it with the novice stack. I gained like 4 lbs or so. Gained about 5 lbs post cycle(how, i dont know). I experianced great vascularity and awsome pumps. But if you ask me is it worth the money, i say no. There are many other product out there worth more for the dollar. the Maxteron may work alone but i suggest a stack.
