There is no such thing as the"best hgh"the substance is either real human growth hormone(somatropin) or it is NOT!!!!! Human growth hormone is a very fragile, large molecule which is comprised of 191 amino acids linked in very specific order and shaped to a very specific form. I'm that regard there is no room for differences!
NOTE: It is not possible to take human growth hormone as a supplement, spray or patch. Sprays, patches, and pills are marketing scams used by the supplement pushers. The growth hormone molecule is too fragile to survive room temperature or vigorous shaking. It's also too big to pass through the skin. If you read the fine print
