I can't speak for the rest of you guys, but I can definitely report that Clenbutrol works for me. Although I used to watch my father and uncles lift weights, it wasn't until I was older that I started doing any serious time in the gym. But once my results began to plateau, I knew that I needed something to help enhance my performance. Thanks to Clenbutrol, I've been able to see double the rate of muscle mass development and far better endurance. Last week, I competed in my first bodybuilding competition and I look forward to my next win.
