HCG comes in a powder form, freeze dried. It sits in a vial and you need to mix bacteriostatic water with it in order to administer. Its a very easy process. Nothing drawn out about it. Just get some bac water, gently trickle that water into the vail using a syringe. For a 5000iu vails, if you add 2.5 ml water, every   “.12” ml of water in the vial will be 250u HCG. You want to draw this and inject it with an insulin syringe so that you can get this small measurement of water correct.
