Unfortunately, some suppliers will  use  GH-elevating peptides such as GHRP-2, GHRP-6 and Hexarelin, which are widely used to manufacture counterfeit GH. These peptides are much cheaper than somatropin because they are easier to produce, but may still result in serum growth hormone elevations. If the buyer goes for a blood test to assess for their serum growth hormones and see a spike in HGH levels, they are fooled into thinking it is a legit HGH product. This can be prevented by using a Growth Hormone Test Kit, which utilizes GH antibodies to identify real growth hormone (somatropin) in GH products, and are very accurate.Some manufacturers actually use a substance called hCG (Human chorionic gonadotropin) and refer to it off as Generic HGH.
