Example HCG Titration Schedule
| Parameter | Details |
|---|---|
| Ovulation Induction | 5,000–10,000 units IM once, 1 day after last FSH dose; OR r-HCG 250 mcg SC once, 1 day after last FSH dose |
| Hypogonadism, Male | 500–1,000 units IM 3x weekly ×3 weeks, then 2x weekly ×3 weeks; OR 4,000 units IM 3x weekly ×6–9 mos, then 2,000 units IM 3x weekly ×3 mos |
| Cryptorchidism, Prepubertal | 4,000 units IM 3x weekly ×3 weeks; OR 5,000 units IM every other day ×4 injections; OR 500–1,000 units IM ×15 injections over 6 weeks; OR 500 units IM 3x weekly ×4–6 weeks. Typical age: 4–9 years |
| Male TRT Adjuvant (Off‑Label) | 500–1,000 units SC 2–3x weekly, adjusted to maintain total testosterone 350–900 ng/dL |
| Spermatogenesis Induction | 1,500–3,000 units SC twice weekly (with FSH) until testosterone normalizes |
| Simeons Weight Loss Protocol (Experimental/Refuted) | 125 IU IM daily, 6 days/week, ×40 total injections, with 500‑calorie/day diet |
| Route | Intramuscular (IM) – standard; Subcutaneous (SC) – with recombinant HCG |
| Reconstitution | For 10,000 IU vial: use 1 mL diluent → 10,000 IU/mL; or 10 mL diluent → 1,000 IU/mL |
| Half‑life | ~24–36 hours (urinary HCG); recombinant HCG ~29 hours (IV) |
Possible vial strengths:

What Is It?
HCG
Human chorionic gonadotropin reference compound.
Bacteriostatic Water
Sterile water containing a bacteriostatic preservative, commonly used when preparing multi-use research vials.
How To Mix HCG
1
CleanUse alcohol swabs to clean the tops of both vials.
2
Draw BAC WaterDraw the selected amount of bacteriostatic water.
3
Inject SlowlyAdd the liquid slowly down the side of the vial.
4
Swirl GentlyDo not shake. Swirl gently until dissolved.
5
Store ProperlyStore as directed and protect from heat and light.
Best Practices & Common Mistakes
Best Practices
- Use sterile technique.
- Protect from light and heat.
- Store refrigerated when appropriate.
- Use clean syringe-unit math before measuring.
Common Mistakes
- Confusing milligrams with milliliters.
- Choosing an option with awkward decimal units.
- Using too little liquid for very small measurements.
- Shaking the vial aggressively.
HCG Storage & Handling
Lyophilized Powder: −20°C (−4°F) for long-term storage (up to 24 months). Refrigeration 2–8°C (36–46°F) for short-term use (up to ~3 months). Original sealed vial in the freezer is safest.
Reconstituted Solution: 2–8°C (36–46°F), use within ~7–14 days. Keep sealed, avoid light, and do not repeat freeze-thaw cycles.

Frequently Asked Questions
An HCG calculator usually measures concentration in IU/mL after liquid is added to a vial. The basic math is total IU divided by final liquid volume, not medical dosing or treatment planning.
No. “HCG levels” usually refers to blood or urine hormone levels, often discussed in pregnancy testing. A reconstitution calculator deals with vial concentration, such as how many IU are present per mL after mixing.
Only partly. The calculator can show IU/mL based on vial strength and final liquid volume, but it should not explain injection technique, frequency, treatment use, or personal dosing.
Not exactly. HCG is better described as a glycoprotein hormone, so the calculator should use hormone concentration math, usually IU per mL. Calling it a peptide can confuse the unit system.
The useful inputs are the total IU on the vial and the final amount of liquid in mL. With those two numbers, the calculator can show IU/mL for research or documentation purposes only.
Practical takeaway: If your real goal is weight or metabolic health, the most useful next step is discussing approved treatment options with a clinician rather than relying on an unapproved compound.
