How to measure 3IU from Pfizer genotropin pen

ad

Hi,

I got pfizer hgh pen but I don't want tocuse the pen I want to withdraw and inject with an insulin needle.

How many ml should I withdraw to get 3 IU or 1 mg.

The dosage of the pen is 12mg/ml but its not written how many ml it has in it, also i tried to search online but didn't find any info on it.

Anyone has an experience with this?

Just use the pen. You just turn the knob or twist it and it says how much you want to use. From what I remember you need the small replacement needle to put on the pen. If you have the needle to pop it on the pen you are done if not just order them they come in a bunch of I think 50 or 100
