Feel Better Guide — hCG
hCG · 10,000 IU vial · mixed with 3 mL BAC water · dosed in IU (not mg)
Informational only — not medical advice. I'm not a doctor, just a girl sharing what's helped me and the people I care about.
⚠️ READ FIRST — this one's measured differently: hCG is dosed in IU (international units), not milligrams. That changes the math a little — but don't worry, the charts below make it simple.
Quick Facts
| Vial | 10,000 IU |
| Mix with | 3 mL BAC water (→ 1 unit ≈ 33 IU) |
| Measured in | IU, not mg |
| Suggested start | 1,000 IU (30 units), 3× per week |
| Best known for | Hormone support |
What Is It?
hCG (human chorionic gonadotropin) is a hormone your body recognizes as a signal to support its own hormone production. It's dosed in international units (IU), which is why the mixing math looks a little different from the mg-based peptides.
IU vs. mcg (in case you see it labeled differently)
hCG is sometimes referenced in mcg. The conversion is proportionate — for reference, 12,000 IU = 1,200,000 mcg = 1,200 mg (so 1 IU ≈ 100 mcg). Don't let the different labels trip you up: we dose in IU.
How It Works
hCG mimics one of the body's own signaling hormones (LH), essentially "tapping the body on the shoulder" to keep its natural hormone production active.
The IU Math (this is the part that's different)
Your vial is 10,000 IU total. How many units on your insulin syringe equal your dose depends on how much BAC water you add. On a standard U-100 insulin syringe, 100 units = 1 mL.
You mix with 3 mL of BAC water, so 1 unit ≈ 33 IU. (The full chart is here for reference, but the 3 mL row is yours.)
| BAC water added | 1 unit (syringe tick) = | A 1,000 IU dose = |
|---|---|---|
| 1 mL | 100 IU | 10 units |
| 2 mL | 50 IU | 20 units |
| 3 mL (yours) | ~33 IU | 30 units |
| 5 mL | 20 IU | 50 units |
Example: mixed with 3 mL (1 unit ≈ 33 IU), a 1,000 IU dose is 30 units. For 2,000 IU you'd draw 60 units; for 3,000 IU, 90 units.
Dosing (not medical advice)
Dosed in IU. A commonly-suggested approach:
| Suggested start | 1,000 IU (30 units), 3× per week |
| Typical range | 1,000–3,000 IU |
| Frequency | 1–3× per week |
At your 3 mL mix, here's each dose in syringe units:
| Dose | Units (at 3 mL) |
|---|---|
| 1,000 IU | 30 units |
| 2,000 IU | 60 units |
| 3,000 IU | 90 units |
Start at the lower end and go from there.
💛 T's Tip
Don't let the "IU" thing scare you, babe — it's just a different unit of measure, and once we set how much water goes in the vial, your dose is a simple number of ticks on the syringe. A good simple starting place is 1,000 IU three times a week — that's 30 units on your syringe. Low and slow still rules here. Mix it, keep it cold, and follow your chart. Easy. — T
Mixing
Add 3 mL BAC water to the 10,000 IU vial. Run the water gently down the side, swirl (don't shake — hCG is delicate) until clear, and refrigerate right away.
At this mix, 1 unit ≈ 33 IU, so 30 units = 1,000 IU.
How Long Will One Vial Last?
One 10,000 IU vial:
| Dosing | One vial lasts |
|---|---|
| 1,000 IU, 3×/week (3,000 IU/week) | ~3 weeks |
| 1,000 IU, 1×/week | ~10 weeks |
| 2,000 IU, 3×/week | ~1.5 weeks |
Side Effects
Generally well tolerated at supportive doses. As with any hormone-signaling product, start low, pay attention to how you feel, and reach out with anything that feels off.
Storage
hCG is delicate. Refrigerate the reconstituted vial (36–46°F / 2–8°C) and keep it there. Don't shake it, swab the stopper each time, and use a fresh sterile syringe for every dose.
Helpful Tips
- Remember: dosed in IU, not mg
- You mix with 3 mL → 1 unit ≈ 33 IU (so 1,000 IU = 30 units)
- Keep it cold and handle it gently
- Start at 1,000 IU and go low and slow
FAQ
Can I combine this with my other peptides? Using more than one peptide is common and perfectly fine — but different peptides should not be combined in the same syringe. A few technically can be mixed, but they don't always play well together, and in some cases they can work against each other, so you lose the benefit of both. It isn't worth the guesswork. Keep each peptide in its own syringe — you can still take them in the same sitting, one right after another. When in doubt, keep them separate.
Why is this one in IU instead of mg? hCG is a hormone that's standardized in international units. It's just a different unit of measure — once you set how much water goes in the vial, your dose becomes a simple number of ticks on the syringe.
Does it need to stay in the fridge? Yes — reconstituted hCG is delicate and should stay refrigerated.
A Little Reminder
New units, same simple approach: mix it, keep it cold, follow your chart, and go low and slow. You don't have to do this perfectly. I'm really glad you're here. 💛
