Hello I am mixing for two ppl! I have one bottle of hcg which is 12000 iu. I also have 30 ml of bac water. We will both be taking a low dose of 120 iu! We will be doing the injections and need to know exactly how to mix the hormone and bac water I have read instructions online and watched videos, but these are for much smaller bottles of hcg! I only have one bottle of 12000 iu and need to mix what I have for the 120 iu does? Can anyone walk me through this (just looking for how much bac water to add to hcg...first to dilute to draw it out into the mixing/storage vial...and then how much more to add of the bac water to finish! Very nervous do not want to mess this up!
