ive never tried them but i hear a lot of people on this site in paticular put down BSN products.
pick up any bodybuilding mag and flip through, whatever you see being whored out the most is probaly no good. ive only used ON Whey and some GNC stuff personally so i can really only speak on that. Im also using Biotest's Grow! Whey right now and their BCAAs as well. Im looking forward to getting their creatine product next. i dont know... maybe ive been brainwashed by this site lol, but i feel they have good quality, PURE, stuff.
