bro, i've used it ,and i've done my homework on it. it is overpriced and does nothing for muscle building. i dont have the the time right now, but do what i did- a search of the site. the search engine is a great tool. the post that i'm thinking of isn't that old either. so i'm sure you'll have a good foundation to make an educated guess. just so you know, i used to be sold on the effects of NO crap.good luck
