I am interested in adding an EAA supp. to my arsenal. I have peaked interest in Controlled Labs Purple Wraath and Primaforce EAA(just hit the shelves). I am just looking for a collection of opionions on how useful it is, especially comparing to BCAA. And is everyone using just one scoop(serving) or more, since at $50 it could be expensive if people arent seeing results unless using a ton. So if you have used any EAA product, whether it be one I mentioned above, bulk or just another product please give me some input. Thanks a lot guys.
