HGH mix

So I’ve just gotten two bottles at 50ius a piece in the mail of Hgh. It needs to be mixed with bacteriostatic water and I’m unsure how much to mix in, I’m wanting to to be where a 1iu pull is 1iu of Hgh. My initial thought is I would mix 50ius of the bacteriostatic water, is that right or is there a formula I need to go by?
