Actually the main ingredient in Hemogex is GH peptide2, which has been used in clinical studies and shown to raise Growth Hormone. Do some research on Gh peptides like GH peptide6, Hexarelin, Semorelin. Is it going to give you the same results as 4iu of Gh a day? probably not. But it will stimulate your own Gh production to some degree. A company called IBE made a product called Hexarelin, which was stronger, but I have gotten good results using Hemogex. I got leaner and fuller and put on a few pounds of muscle. Of course I know how to train properly and diet as well.
