has anyone else tried this protein? it has a high amount of glutamine per serving and im just wondering if maybe that in itself can cause diarreha?
Hardly!!
In fact, I just bought two jugs of Nitro-Peak (Chocolate Peanut Butter) on clearance at Vitamin World for $12 each. It tastes pretty good. But, if you want a protein shake that's REALLY YUMMY, get the Strawberry version of either Nitro-Peak or Mass-Peak.
