I have blue-top chinese GH, but they are no longer generics. They are brand-name "Hygetropin" now. On 8iu/day, I had to back off to just 2iu/day this week b/c my fingers and arms were getting so damn numb. Definitely real, I've never gotten the numbness and tingly feelings before, and I've run Humatrope, Jintropin, and Nutropin Depot and AQ. Never been to 8iu/day before, obviously that's too high a dose for me at this point... but anyway, they're real, and they work.
