I do have references for glutimine. i'll have to look through some of my stuff but yes i do. i've read multiple researches on it. I'll post something on it.
i don't think glutimine directly will show you much benefit. i think it plays more of a role in aiding your other nutritional aspects. like helping your body shuttle protein into the muscles, and recovery, that sorta thing. but just adding glutimine alone i agree, you wont see much benefit of it.
