A buddy of mine just started HGH--6iu/day. After 2 days, he has been experiencing cramping in his abdominal region and headaches as well as not being able to sleep all that well. I'm wondering if these sides are possible from the HGH or maybe something else he's doing (he's only doing test that I know of).
I'm wondering mainly because, I'm considering HGH from his source and I know how much fake stuff there is out there.
