I got my IGF-3 today , wow two days. I have 1/2 cc insulin syringes. You said to withdraw .9 of normal saline. Is that 9 units or 90 units of normal saline. 90 units of normal saline would be 0.9 of a cc but at that rate I would only have enough normal saline for 11 days not 20. Help me out with the dose please
