I have taken this supplement and it doesn't produce results. It
is a dietary supplement that you take 30 minutes before your workout and
it's supposed to help muscles recuperate and grow faster. I didn't
see any results beyond normal lifting results. I will not purchase
this product again.
You can find this product at GNC.
