Iv been using these bluetops lately and they have been really good showing full effects of what HGH can do. Though my friend had a blood test done and his igf levels came back the same before and after. Could any1 clear this up as to why this would of Happened. He used some hgh just before he had blood test aswel. I'm am assured that these are the real deal and what Ellse chemical could mimic, fatloss, better well being, deep sleep, carpal tunnel. Am confused.
