I recently bought some Grow! protein, which I've been very happy with. Unfortunately though, it is missing some essential amino acids, such as L-Glutamine. The GNC protein has these. Why doesn'y Grow! have it? Also, does Grow! use a mix of proteins, or just whey protein? Thanks a lot.
PS: As far as the weight gainer "N-Large 2" goes, does anyone reccomend it? It need extra protein and caleries as I am a hard-gainer, and this stuff doesn't have too much sugar. Thanks
