When purchasing Hcg, I highly recommend you buy the 2000 unit vials. This way you can mix more frequently and be using Hcg that is relatively fresh. Most people find that there is a noticeable decrease in potency after 12-14 days- they become hungry, and lose less weight.

So if you’re going to use a vial of 2000 units, and use a dose of 200 units per day (for sub-q shots), that vial will last you 10 days. To do a round anywhere from 23-30 days, buy 3 vials. For a 40-day round, buy 4.

If you decide you want to use the vials of 5000 instead, one vial (at a dose of 200) will last you 25 days so that is sufficient for a short round. For a 40-day round, buy two vials and re-mix after 20 days.

If you’re going to share a vial with a friend, one vial of 2000 will last 5 days for you both; a vial of 5000 will last you both 12.5 days.

For sub-lingual hcg, the most common dose is 166 units, twice a day. Thus, a vial of 5000 will last you 15 days. For a long round, buy 3 vials and re-mix after 14 days. For a 23-day round, buy 2 vials and re-mix after 12 days. For a 30 day round, you’ll use exactly 2 vials.
