There is definitely a lot of Generic/Chinese HGH out there that is bunk, but that is why you do not go out and just purchase "blue tops" or "red tops" from any random dealer on the internet.
There is proven bloodwork from multiple people on the internet right now that show HGH such as Godtropin, Kefei, Angtropin, Grey tops (purchase from a dealer that has had buyers that have actually posted IGFs) are consistent.
Some generic/chinese HGH is actually OVERDOSED in comparison to pharma. Non-pharma just gets a bad rep because there are a lot of shady dealers out there. If you see good IGF readings on Angtropin, than find out the source that they were purchased from.
