Bro i went through 2 bottles of it, saw little difference... waste of money IMHO. Nothing wrong with trying it and experimenting with supplements. I did that for a few years, wasted alot of money... but I learn better first hand didn't want to listen to anyone then.
I benefited much greater when I overhauled my diet than ANY supplement I ever tried... cardio never hurt either.
Looking good is never easy, nor found in any bottle. Sucks to come to that realization, but very true.
