GH serum test will let you know if it is fake. For example, the reference range for GH serum test is generally 0.1-3.0. So like mentioned, you need to inject 10ius in the muscle. Not sub-q. Inject in the muscle. I shot mine in my delt. Then you need to get your blood draw 3 hours later give or take 15 minutes before or after that. My last GH serum test for Kefei GH was a 29.1. So when you look at that reference range of 1-3, and I have a 29.1, that shows you that I got some pretty good stuff. I have seen tests higher. and lower but 29.1 was good for sure. I have also tested some Jintropin GH I got a couple of years ago and the GH serum result was a 0.1. That obviously told me I didn't have any GH in my vials. What was I injecting?? Who knows. Could have been HCG. Everyone who gets GH should do this test. Being that you are out of the country, look around and get that test done. As for IGF, I have seen results from 300-500 but I know the timing is a little different and maybe someone can shed some light on that.
