The ones that i know of are 10iu and legit. Why dont you ask the person who has them what they are. I seen some that just came out that were 8iu, but they have been 10iu in the past 6 months.
"enhanced genetics", "shanghei united", "elramoz" all get their Generic GH from one of 2 people. In either 4iu, 8 iu vials or 10 iu vials.., and it all test out at least 96% purity. The brown-bugundy are the most popular and then the blue IMO. Most of this stuff is coming from the same place.
