Bros, I always come to this forum because I always get great answears from the people that really know! I am going to tell you a little more about my me so you get a better Idea. I am 27 years old, and ofcourse after my 25th birthday I have been noticing some normal aging patterns (Which I don't like). I was reading about HGH on this forum to try to learn more about it, and I came across some information that says that people who are young in thier late twenties and up can stimulate thier own production of HGH buy using some supplements the first one is L-Glutamine and the Second one is L-Arginine. Now I have been doing my reasearch about L-Arginine and for it to work it has to meet a lot of different criterias ex: Pure formula of 5g to 10g, it has to be pure, no other aminos or vitamins on it in order to be effective. Has anyone used L-Arginine as a supplement? Is so can you guys tell me your experiences and where would be a good place to purchase it (Good quality). Thanks bros in advance for your help..
