But when you get right down to it, the most important role of glutamine for athletes is gut health. If you're an athlete competing in endurance-based sports, glutamine may help prevent upper-respiratory infections. If you simply slam the iron, a few grams of glutamine isn't going to do squat.
Put simply, I don't know of a single study in humans that shows glutamine has anabolic or anti-catabolic properties that increase training adaptations during resistance exercise. That includes a terrific
study from Canada in which subjects were given 45 grams of glutamine per day during a six-week training program. Compared to the placebo group, subjects consuming glutamine had no greater increases in strength (measured via squat, bench press, and knee-extension torque), body composition (lean mass determined via DEXA), or muscle-protein breakdown (determined via urinary 3-methylhistidine excretion).
So ultimately, my take on glutamine and weight training is this: If you're into micromanaging things, glutamine probably won't hurt your efforts in the gym. But it almost certainly won't help.
cheers for all the positive comments guys I'm really happy with the way its going at the moment and yes its also had the positive effect of helping me regrow my head 
You're all around twice my age.
