I am not for muscletech at all, but a buddy of mine gave me a bottle of it, so I wasn't going to turn away free supplements (since
Gakic can't hurt you) I said why not, honestly I found that it did in fact allow me to workout harder longer, definately noticed a increase in my muscular endourance. Now I was floored by this because its MuscleTech, but I will give credit where credit is due, I think its a decent product, all they really have to do is work on the price on it, and I would put it into my stacks.
