The Ultimate Nutrient: Glutamine/the Essential Nonessential Amino Acid
by Judy Shabert, Nancy Ehrlich (Contributor), 1994.

this book wasn't a supplement ploy, yet it related glutamine to many positive effects, including anti-stress, liver friendly, anti-catabolic.
I think we must take things with a grain of salt or two....
If we look at hyped, over priced supplements & outrageous claims like " increase GH 400% ", then that's rubbish.
If we buy fairly priced glutamine hoping to get muscle/liver/anabolic friendly benefits, then we're right.
A few grams are enough, not to trigger the ammonia response.
If we hope to raise GH 400%, triple protein synthesis etc, then perhaps not even Anabolic Androgenic Steroids (AAS) can do that.

Dr. Colgan states glutamine ( high dosages ) can saturate one's system with ammonia. Recently he moderate his position a bit but only adding that AKG ( ketoglutaric acid ) should be added to glutamine to scavenge ammonia.

Unfortunately i don't.
it was written on some newletter/booklet published years back i got stuffed in my cellar.
Recently on another board the owner said to have prompted dr.Colgan about it, which got the quoted reply back.
