Rambo, GNC protein is far from cheap. It's overpriced. Workoutfanatic8, protein is protein in the context of a high protein diet, your body doesn't care.

1. dont consume soy. ever... it is latent with toxin (due to fertilizers and pesticides) and its bad for males. 2. pursue makes individual chicken breast bags ("Select sized" is what they call it) -- I think thety sell it at costco, meyer, sams club, and some regular stores --they are ~100 cal each and have 24g protein -- pretty much exactly the same as whey protein. read labels and try to find close substitutes if that is what you would rather do.
