Couple of IGF-1 LR3 questions

[bobtail]

I know how to reconstritute and understand dosages. From my research, you add acetic acid but it seems you add some sterile water to make it not burn. So lets say I add 1ml of acetic acid to a 1mg IGF vial, that's going to yield 10mcg per IU on a slin pin. If my dosage is 20mcg (2 IU) then how much sterile water would you typically add? Do you add it to the vial or do you add it to the pin before injection?
Thanks!

Answered my own questions: You add it to the pin and it should be twice as much as the IGF. So in my case, I'll suck up 2IU of the IGF and add 4IU of water for a total of 6IU of liquid.
Does anybody have any experience with this stuff? I don't want to do IM bilat so I'm going to pin pre workout. Suggestions?
