Bro you making this way too complicated. There is no mystery to this. You should be using an insulin syringe to inject your GH. You say you have a 12iu bottle of gh. Then add in 1.2 cc of bacteriostatic water. That way, 0.1 cc is equal to 1iu of gh. Insulin syringes are maked in units of INSULIN, not GH. The 10 on the insulin syringe is equal to 0.1 cc. So if you have insulin syringes and want to injuect 2iu of the mixture I told you to reconstitute at, then you would draw out to 20 on the slin syringe, or 0.2 cc.
