How I Find My Dose of HCG on an Injection Syringe

Finding the Right HCG Injection Dose.

When you are new to the hCG diet, and HCG Injections, it can be pretty overwhelming.  Phrases like “syringe” “iu’s” and “bac water” can really throw us off and make the HCG diet feel intimidating.  But it doesn’t have to be that way.  I guarantee if you take the time to continue to research and read up on the diet, things will start to click.  To help you in that way, I thought I’d demonstrate how I go about getting the correction hCG injection dose.

If you are here, you are most likely interested in learning other stuff like how to inject and such so you can you find all my hCG injection tutorials here, including a live demo where I stick myself with a needle for your benefit even though I’m no longer on the diet just to show you how not a big deal it is. How’s that for love?? 😉

And if you are still in the research phase for purchasing hCG, you can compare my current recommendations for RX pharmaceutical hCG that can indeed be purchased online (and comes in powder form, as it MUST if you are using the real hormone) here:

On to the lesson folks!

Lesson 1: What the numbers on the Syringe mean

The “syringe” part of the injection is the barrel that will contain whatever you’re going to inject and it has little numbers and hash marks to indicate how much it holds. The numbers on the syringe are referred to use “units” and 100 units = 1cc or 1 ml. The most common syringe sizes I see come with the hormone diet kits are 30 unit syringes(.3 cc/ml), 50 units syringes (.5cc/ml) and 100 unit syringes (or 1cc/ml). Please note – some who are purchasing their injection kits from Escrow Refills are receiving different syringes that have 40 units per 1cc/ml syringe (instead of 100 units per 1 cc) and my following instructions will NOT apply for these syringes – see the bottom of this post- LESSON 4- for the proper dosing with these syringes.

Whatever size syringe you get, you can use this video to figure out how to draw up the proper dose of the hormone.

Lastly the way the units (numbers) are written on the syringe could be one of two ways:

  • Either you’ll see numbers that say 5,10,15,20,25 etc.
  • Or you may see numbers that say .1,.15,.20,.25 (with a decimal).
  • These numbers are technically the same. .15 is the same as 15 units. .20=20, etc.

Lesson 2: Finding your dose of hCG on the syringe

For 1:1 ratio mixture only

The following ONLY applies if you have mixed the hormone in a 1:1 ratio- that is, if you have a 5000iu vial of hCG, you would have mixed it with 5ml’s of bacteriostatic water, AND if your syringe is one of the following:

  • 1 ml/cc syringe = 100 units
  • .5 ml/cc syringe = 50 units
  • .3 ml/cc syringe = 30 units

Here are the following dosages and where to draw up on the syringe:

  • 125iu dose = 12.5 units (or .125) – sometimes the barrel is labeled slightly differently.
  • 150iu dose = 15 units (or .15)
  • 175 iu dose = 17.5 units (or .17)
  • 200 iu dose = 20 units (or .20)
  • 225iu dose = 22.5 units (or .22)
  • 250 iu dose = 25 units (or .25)

Sometimes there may  not necessarily be a hashmark with the actual number labeled on it- it may be one of the inbetween hashmarks- but I think you get the picture.

HCG Dose Syringe

Finding Dose For 2:1 Mixing Ratio

The following applies if you mixed your hCG this way:

10 ML’s of Bac Water with 5,000IU hCG

  • 125iu dose = 25 units (or .25) – sometimes the barrel is labeled slightly differently.
  • 150iu dose = 30 units (or .30)
  • 175 iu dose = 35 units (or .35)
  • 200 iu dose = 40 units (or .40)
  • 225iu dose = 45 units (or .45)
  • 250 iu dose = 50 units (or .5)

Lesson 3: How To Keep Air Bubbles Out

When you pull your hCG mixture out into the syringe, the easiest way I feel to do it is to hold your bottle of hCG upside down to draw the mixture out. As you pull out the hormone, make sure you don’t have any huge obvious air bubbles. If you do, simply eject the hormone back into the vial and try again (without pulling the needle out and into the vial again- that will dull it too much and make your injection hurt).

Don’t let the mechanics of the protocol prevent you from losing weight and experiencing a weight loss journey similar to mine.

Lesson 4: Finding Your Dose of HCG With a Syringe that Has 1 ml/cc per 40 Unit Syringe (only when from Fast Escrow Refills)

For the moment I’m going to just past my email to the gal who wrote me saying she ran out of her hCG in 11 days when it supposed to last her a month from escrow refills- we discovered they are now sending some people different syringes – the following should help you find the dosage you desire with these odd syringes.
Okay so here’s how the syringes are usually:
1 ml/cc syringe will contain 100 units total
.5 ml/cc syringe will contain 50 units total
.3 ml/cc syringe will contain 30 units total.

See how that is and how it matches up?

But these syringes have:
1 ml/cc syringe contains 40 units total (when usually it would contain 100 units)

What this means is that you cannot use the general instructions that you find on the web for dosing (including my website) or you end up taking a much higher dosage of hCG than you thought, and your vial would run out much faster than usual.

Now again, this math is based on the knowledge that the hCG was mixed in a ratio of 5000ius to 5mls bac water to begin with okay?

So 1 ml/cc = 40 units in this case.
1 ml/cc contains 1000 iu’s of hCG right (if you mixed 5ml’s bac water with 5000iu hCG)
So if you filled one of your syringes all the way up, it would contain 1000ius in that 40 unit syringe.
40 units = 1000 ius’ of hCG then (for your syringe)
1000iu/40units = 25iu’s per unit
If that is so, then,

If you want a dosage of
125 ius then we would divide 125 (dosage desired) by 25 ius per unit = 5 units should be taken.
150 ius dosage would be divide 150 by 25 ius = 6 units should be taken
175 ius dosage, divide 175/25ius = 7 units should be taken
200 ius dosage, divide 200/25ius = 8 units should be taken
225 iu dosage, divide 225/25 ius = 9 units should be taken
250 iu dosage, divide 225/25 iu = 10 units should be taken

So again:

  • 125ius hCG dose = 5 units
  • 150 ius dose = 6 units
  • 175 ius dose = 7 units
  • 200 ius dose = 8 units
  • 225 ius dose = 9 units
  • 250 ius dose = 10 units

Remember, this is ONLY for the syringes that have 40 units per 1ml/cc – the barrel of your syringe should tell how much the syringe can hold total – here is the syringe I’m talking about:

    Scared too death of injections! Any suggestions? Someone told me to ice the area so I don’t feel it.

    • HCGChica

      Hi there +MB – I know it SOUNDS scary- believe me I never intended to use injections myself- I too thought they sounds scary and painful and I had in my mind those big needles used for vaccinations when I was a kid. In actuality, the tiny is literally so short and thin that you actually feel nothing. I’m serious. I made my husband do my first injection because I was just that scared and I didn’t even realize when he had put it in because I literally felt nothing. The key is to inject into your fat. It’s really quite painless. I hope that helps.

    • AML

      I was scared too! I did my first round at a clinic and they had me inject myself before leaving (with a B12 shot) so I could get the hang of it. You really don’t feel anything if you pick a good spot, you’ll find your favorites. My favorite spot to inject is on the sides of my abdomen, near the hip at the level of my navel. I pinch the fat, wipe with an alcohol swab then stick into the fat roll. If you go too near the navel it gets more ‘pinch-y’ in my experience. I alternate sides every day to avoid bruising.

  • AML

    I find it helpful to draw a little air into the syringe before inserting the needle into the hCG vial, then push out the air and draw back to fill. Never get any bubbles that way. This is the best instructional video for dosing with syringes, awesome job :)

  • Jeri Reisdorfer

    Our needles start with 10, 20,30 up to 100. In other words they go by 10’s and each hash mark between go by 2’s. Example: Between 10 and 20 there are 4 other marks. 10 12 14 16 18 20. Very difficult to see where 12.5 or 15 would be! My son will be doing it and from what I read men do better on 200 so at least he can use them easier then me! Just thought I’d let you know there are other types out there. Thanks for your blog. It’s been very helpful. We are not newbies to hcg but we were mixing 30ml to 5000 and doing 50 unit shots.

    • HCGChica

      Hey @jerireisdorfer:disqus Yes I had those syringes before too I think- I think you just get as close as you can, that’s all. Men do seem to do better on slightly higher dosages from my observation as well- between 175-200ius often times.

  • joana moreno

    what if needle says 0.1, 0.2, 0.3 and at the end barrel says 1.0……at what number do I fill up…….i mixed 5 bacteriostat water with 5000 iu……confused

    • HCGChica

      Hi @joana_moreno:disqus – as long as the needle you have is either a syringe where 100 units = 1 ml/cc, or 50 units = .5 ml/cc or 30 units = .3 ml/cc, then the .1= 10 units=100 iu’s of hCG, .2= 20 units=200 iu’s hCG In the mixing ratio you mentioned. If you want to post a picture you can.

  • Bridget

    My doc is starting me at 250, isn’t this a bit much for me? I’m 5foot 4 inches 160lbs 36 yr old woman.

    • HCGChica

      Hi @disqus_X5XAyRdz8L:disqus I’m not a medical professional of course, I’ve just seen in my own experience and observing what works best for most people. I talk in detail about this in this post if you haven’t seen it yet: I don’t want to get between you and your doc, but that article has what I have observed to work best for most people and helps you gauge what dosage will be best for you personally. I have to be careful getting in the middle but all I can say is that its good to do your own research and take charge of your own body! :)- Let me know how things turn out! – Rayzel

        Thank you, and I appreciate your response. I think I’m going to lower it, and then see how i feel. Thank you!

  • Michaelopolous

    Hi HCGChica. Amazing site by the way…my sister swears you are awesome, so thanks for your contributions and the enormous amount of work you put in are an incredible motivation to many. I am starting my HCG tomorrow (it was supposed to be today but I screwed up and injected 5 instead of 12.5 or 17.5.) I have the exact setup as you stated above… 5,000 IU. The HCG is mixed as instructed and I am ready to go. I’ve done HCG once before and it was at 12.5, I was hungry all the time (Male, 6′ 190 lbs). If I change my dosage to 17.5, will I have enough HCG to get me through phase 2? Also, for phase 1..loading days. I know you have to gorge..but do you have a handy gorge guide? I can eat 20 doughnuts an hour all day..but I want to really optimize this round.

    • HCGChica

      Hiya @michaelopolous:disqus I have seen that most guys tend to do better with slightly higher doses than females. Regarding enough – one 5000 iu vial will last you 28 days at 175 ius (17.5) – I have a tutorial here to figure out how long a vial will last you at any dosage: That will help you as well. My best advice on loading is actually to load clean and skip the donuts – I know you probably don’t want to do that! Here is my whole section on loading with everything I’ve discussed at this time about it and includes a post on what clean loading is etc: I hope that helps get you started! Thanks for stopping by. If you finish and feel good, I’m always looking for more males to interview on the blog because they are harder to find- all hiding under rocks or something 😉

      • Michaelopolous

        Hi HCGChica, Thanks for getting back to me. I followed the directions but for some reason I must have miscalculated. I used the measurements.. 5cc..-1cc in the hcg, mix and put into vial (totalling the 5cc). Since then, I have been injecting 17.5 each day. Its now day 5 and I have 19 days left for phase 2. HOWEVER, I need your help, the bottle seemed to go very rapidly and I was getting really concerned, I used an empty vial to see how much I have left and I only have enough for 6 more days of injections and I’ll be out. So I must have really screwed up something and I don’t want to stop and start over either. My original HCG came from EscrowRefills but they take forever to send it. I saw your other sources but they all sell the whole kit, I only need the HCG (I have everything else available). Do you know if anyone of them can help and overnight me the HCG so I can mix a new batch before mine runs out? By the way, would be happy to be interviewed on the blog :).

  • Lana Brown

    I just received my vial of HCG. It is premixed. It is only a 1000 IU bottle and I have to do 150 units a day. Does this mean my bottle will only last about 6 days?

    • HCGChica

      Sorry for late reply- yes the 1000iu will not last you very long. Usually it’s best to have a 5000iu vial that will last 3-4 weeks. @Lana Brown

  • Nichole Techter

    So I was feeling ravenous around 4 pm on 125 iu and my doctor’s response was to do an additional 125 injection at 4 pm. I’m on day 11 of the my first round. I just wanted to ask you if you’ve heard of this? Taking an additional dose in afternoon and basically doubling the amount? Does this sound normal to you? Do you inject just once in the morning? Thanks in advance for your input!

  • Robert

    Thank you for the outstanding info.
