Depending on how big the vial is, you might need to get an empty sterile vail. You also need bacteriostatic water. Not the water that comes with it. Thats sterile water and does not last early as long once mixed. For a 10k vial, if you mix 5ml bac water with it, every 1/2cc will be 1000iu. If you have a good sterile vial thats larger, you can mix some of the water with the hcg, then transfer it over to the larger vial. Then mix the rest of the water in. From there, you can dose it out as you plan on doing. Just remember the math. If you do 10ml in a 10 vial, each 1ml is 1000iu. If you mix 5ml in, every 1ml is 500iu. As for how much to take, I suggest 250 to 500iu every 3 days during cycle right up to PCT
