I am having a heck of a time figuring out hgh/somatropin. I have recently gotten a “script” without directions wink. I have searched and deduced that a first run of 4iu/day may be a good start. My issue is calculating on an insulin syringe or a larger 3ml. I am not stupid enough to give ml. What I can’t seem to calculate, nor find a calc for is iu>ml or mch. I would appreciate some help on this to avoid problems. I have searched and it seems all info is in iu, which is a new thing to me. I’ve always been able to calc ml/mcg but I know iu is different.
