Can you elaborate? Believe me I'm not questioning you, I love the knowledge on supplements you've brought to the boards, I'd just like to hear more information. More specifically about 'the studies on it on exercise and performance swing the other way for bulk.' Do you simply mean the studies have been inconclusive, and the product may not do anything, or do you mean it could be detrimental to bulking?
Thanks
Glutamine... You can keep it and it is fine, BUT i'm going to tell you that the studies on it on exercise and performance swing the other way for the bulk, as meaning it doesn't do quite what we think it does. Still in the study stages, and there are a handful that show it in the positive sense.
Here is what I had posted a few pages back when talking about glutamine again. Most recent ones out there, and I can go back if needed.
The reason I say maybe on the glutamine is that there arent too many studies that support it on the positive side. More are the opposite.
One of the most recent...

Glutamine is a popular dietary supplement consumed for purported ergogenic benefits of increased strength, quicker recovery, decreased frequency of respiratory infections, and prevention of overtraining. From a biochemical standpoint, glutamine does play a physiologic role in each of these areas, but it remains only one of a host of factors involved. This review examines the effects of glutamine on exercise and demonstrates a lack of evidence for definitive positive ergogenic benefits as a result of glutamine supplementation.
Addition of glutamine to essential amino acids and carbohydrate does not enhance anabolism in young human males following exercise

The addition of glutamine to a CHO + EAA beverage had no effect on post-exercise muscle glycogen resynthesis or muscle protein synthesis, but may suppress a rise in whole-body proteolysis during the later stages of recovery.
What I am saying is that there needs to be MORE studies done on glutamine, like has been on creatine. Then when we say... Oh look, 50 studies with exercise and glutamine show it does something over the 5 that doesn't. You go with the 50.
Right now you cant really do that, and it sucks.
Again we have to also state EXACTLY what reason it is we take something. I can take protein to increase my wang size, but it wont do that.
Now just cause one supplement may not be effective at one thing, doesn't mean it isn't effective in other areas of research.
