So I have just been prescribed some HGH by a new doc. I had been testing low for years, but the other docs would not give it to me solely based on the fact that I was muscular. Didn't matter what the test said. Anyway, so now I have a script. I was prescribed Omnitrope 5.8mg, and I'm supposed to take 0.2mg to start, and my doc wants to work me up to possibly 0.4mg. This is a little confusing to me since I've only heard of HGH in units, iu. When the pharmacist showed me how much 0.2mg was, that was the 4th tick on an insulin syringe. So how do you work the conversion? Supposedly, this vial of 5.8mg is supposed to last me about a month, 5 days on, 2 days off. How do I convert from the mg to iu? Am I actually taking 4 iu if it's the 4th tick mark or is it actually something else? Posting this here in this forum for hopes of more replies.
