I'm confused...am taking miniquik Genotropin shots and am confused about testing my HGH levels...I had IGF-binding protein 1 tested...it came in at less than 5.0 L...reference range said it should be 13-73...did I get the right thing tested?...I thought HGH levels are tested as IGF-1 (different than binding protein 1?)....and the range should be something like 90-318....help please.
