hi. i'm taking glutamine supplements for my athetlic performance. i heard that the supplement glutamine helps not only muscle growth but also muscle performance. i understand that it does help the muscles and that it is already naturally produced in our bodies, but i have also heard and read that glutamine is an amino acid that also helps trigger the secretion of HGH (human growth hormone). is that true? i also heard that glutamine triggers the secretions of HGH in higher quantity than usual. is that also true? could glutamine be used for not only muscle growth but also bone growth? thanks
