Don't waste your money. It is pusedo science at best. They take a little science and put a huge spin on it. Did you happen to read one line in their sales...states, if our guess is right? Should set off alarms right there. They are covering themselves. Check out a post in the supplement area here. Someone put up a great piece about just this.
They tried to talk you into it because everyone knows it doesn't work, but they need someone to buy it. Do a search for 'myostatin' in this forum and you'll find all the info you need.
