I have used it twice. The first time I used it my strength gains definitely went up and I just felt leaner and dryer all the time. Then after a week the results seemed to fade and after 2 weeks I got quite sick so I stopped. I did another cycle of it, just to see if it was the MENT that made me sick, and sure enough after 2 weeks or so I felt horrible and the results did not seem to be as good as the first time I used it. Im guessing that the strain on my liver caused the sickness. Would I use it again? Maybe as a kick start to a cycle, but only for a week. Hope this helped
