The easiest way to tell, besides having blood work done, it to use a home pregnancy test. Mix up your GH and load an insulin pin all the way up...1cc. This is 10iu if you reconstitute your GH with 1cc of BA water per 10iu vial. Pin the entire amount tonight approximately an hour and a half after your last meal. When you wake up to pee in the middle of the night or first thing in the morning, pee on the pregnancy test. If it's positive, you purchased some very expensive HCG. HCG is commonly used as the ingredient in counterfeit GH. If it's negative, just dose as you normally would and you will be able to tell in a matter of days if it's the real deal from common sides.
