Since I've been on HCG for a while, I thought I'd make a little tutorial of how to give yourself a subcutaneous HCG injection. HCG is used primarily post-peak to increase estrogen and progesterone levels. It's one of the first treatments NaPro doctors recommend for PMS.
Make the HCG solution
My HCG comes in a solid form and needs to be reconstituted in water. The pharmacy sends it this way so it doesn't have to be kept cold during shipping. The vial contains 10,000 IU of HCG. I add 7.5 mL of water resulting in a solution where 1.5 mL = 2,000 IU.
*A note about needle gauge: I've used syringes with a gauge ranging
from 20-23 for reconstituting HCG. It just depends what the pharmacy sent me or what I have on hand. The larger the gauge, the smaller the
needle.

Gather the supplies: vial of bacteriostatic water, HCG vial, 3 mL syringe, and alcohol wipe(s).
Remove the plastic cap from the top of both vials. (They are already removed in the picture to the right.)

Obviously I took the picture on the right after I added all
the water...just pretend you can't see the liquid. |
Wipe the top of each vial with an alcohol wipe.

Remove the cap from the needle. Fill the syringe with air.

Insert the needle into the vial of water.

Flip the vial and syringe upside down. Press the plunger all the way to inject air into the vial of water. This will make it easier to fill the syringe.

Pretend this was a picture of the vial of water from
the previous picture. The concept is the same for
filling the syringe with either water or liquid HCG. |
Make sure the needle tip is covered by liquid. You don't want to draw up any air into the syringe. Fill the syringe with 3 mL of water. You will likely have air bubbles in the syringe as you're drawing up the water. Flick the side of the syringe barrel with your fingernail or knock it gently with your knuckle to force the air bubbles to rise to the top. Press the plunger upward slightly to release the air bubbles back into the HCG vial. Draw more water into the syringe if necessary to reach the 3 mL mark.

Remove the needle from the vial of water and insert the needle into the HCG vial. Inject the water into the HCG vial. Repeat this again with 3 mL of water. The third time, fill the syringe with 1.5 mL of water. This will be a total of 7.5 mL of water added to the HCG.

Invert the HCG vial several times to mix the solution thoroughly.
Write today's date on the vial. The HCG is good for 60 days from the date of reconstitution.
If you're not giving an injection right away, put the reconstituted HCG in the refrigerator.
Give the HCG injection
*A note about needle gauge: I've used syringes with a gauge ranging from 22-25 for HCG injections. The larger the gauge, the smaller the needle. So go with a 25 gauge needle if you have a choice.

Wipe the top of the HCG vial with an alcohol wipe. Also use an alcohol wipe to clean the area of skin where you plan to do the injection. I clean a large area of skin so I don't have to aim for a particular tiny spot.
Wait a little while for the alcohol on the top of the vial to dry. Do not fan it (or your skin) to try to speed up the drying.

Remove the cap from the needle. Fill the syringe with a volume of air equal to the amount of HCG you want to inject.

Insert the needle into the HCG vial. Press the plunger down all the way to inject air into the vial of water. This will make it easier to fill the syringe.

Flip the vial and syringe upside down.

Make
sure the needle tip is covered by liquid. You don't want to draw up any air into the syringe.
**Note: My prescription says each dose of HCG is 2,000 IU. This is 1.5 mL of HCG according to my directions for reconstitution above. Adjust the volume accordingly if you are prescribed a different dose.

Fill the syringe with 1.5 mL of HCG. You will likely have air bubbles in the syringe as you're drawing up the water. Flick the side of the syringe barrel with your fingernail or knock it gently with your knuckle to force the air bubbles to rise to the top. Press the plunger upward slightly to release the air bubbles back into the vial. Draw more HCG into the syringe if necessary to reach the 1.5 mL mark.
Remove the needle from the vial.

Very gently press the plunger until a drop of liquid appears at the tip of the needle. That way you know you've pushed all the air bubbles out.

Pinch the area of skin you plan to inject with your non-dominant hand. I do the injection in my outer thigh. I just can't handle the thought of doing an injection in my belly.
Hold the syringe in your dominant hand. In a quick motion, like you're throwing a dart, stick the syringe into your (pinched) skin so the needle goes in all the way.** Press the plunger down to inject the HCG until you've injected all of it. Remove the needle from your skin.
**If you do the injection correctly, you should barely feel the needle going in. It can be virtually pain-free.

If you are super careful, put the cap back on the needle. Untwist the needle to separate it from the syringe barrel. Put the needle in your sharps container. Cleaned out, hard plastic bottles work well. I use an old plastic olive oil bottle. A laundry detergent bottle would work too. Throw the needle-less syringe barrel in the trash.
Store the liquid HCG in the refrigerator. Discard 60 days after reconstituting it if not used.
If you prefer watching a video tutorial, search Y.outu.be. I watched a few videos before attempting to do the injection for the first time.
