Whoa....100 units = 1ml OF INSULIN on an insulin syringe, not GH!!
All GH reconstitutes to a different concentration. For example, serostim - 1ml = 18 iu OF GH, not 100. Saizen - 1ml =.75 iu GH. You have to read the directions and do the math on the conversion. If I wanted to do 4iu of serostim GH, that would be just under .25 ml on an insulin dart.
