HOW TO MIX HCG
Use a larger bore (like the ones you use to do your test cyp with) needle, and transfer the bacteriostatic water to the vial with the powder in it, 3ccs at a time. Keep the powder vial upright, because you will blow HCG out of it when you pull the needle out otherwise (be sure to draw air out after you push water in to release pressure each time). Gently swirl to mix. Keep in the refrigerator. Simple as that.
You will then have 10,000IU of HCG in 10ccs. Therefore, each 1cc contains 1,000IU of HCG. When using an insulin syringe, each unit on the scale of the insulin syringe equals 10IU of HCG. 250IU of HCG is then 25units on the side of the insulin syringe.
There is no reason to use a larger bore needle than 30 or 31ga, at 5/8.
My HCG protocol is to use 250IU of HCG two days before, and one day before, their testosterone cypionate IM injection. Androgel users take it every three days. The HCG is injected with an insulin needle, subQ within 6 inches of the navel.
