Description
HCG Dosage Chart
HCG is dosed at 500 IU weekly via subcutaneous injection in educational protocols. Reconstitute the 5000 IU vial with bacteriostatic water before use. This information is for research and educational use only.
- Reconstitute: Add 2.0 mL bacteriostatic water → 2,500 IU/mL concentration.
- Typical dosing: 500 IU subcutaneous, 3× weekly (Mon/Wed/Fri) for testicular maintenance during TRT.
- Easy measuring: At 2,500 IU/mL, 1 unit = 25 IU on a U‑100 insulin syringe.
- Storage: Lyophilized: refrigerate at 2–8 °C (35.6–46.4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) for up to 60 days.
Human Chorionic Gonadotropin (HCG) is a glycoprotein hormone that mimics luteinizing hormone (LH) by binding to LH receptors in the gonads. With a 36‑hour half‑life (compared to LH’s 30 minutes), HCG provides sustained stimulation of testosterone production in men and ovulation induction in women. This educational protocol presents a practical three‑times‑weekly subcutaneous approach for maintaining testicular function and fertility.

Dosing & Reconstitution Guide
Educational guide for reconstitution and intermittent dosing
Standard Protocol (2 mL = 2,500 IU/mL)
| Week/Phase | Dose per Injection (IU) | Units (per injection) (mL) |
|---|---|---|
| Weeks 1–12 | 500 IU | 20 units (0.20 mL) |
Frequency: Inject 3 times weekly subcutaneously (e.g., Monday/Wednesday/Friday). This yields a total weekly dose of 1,500 IU. This schedule maintains intratesticular testosterone during exogenous testosterone therapy and supports fertility preservation.
Reconstitution Steps
- Draw 2.0 mL bacteriostatic water with a sterile syringe.
- Inject slowly down the vial wall; avoid foaming or vigorous shaking.
- Gently swirl or roll until the powder fully dissolves (clear solution).
- Label vial with reconstitution date and concentration (2,500 IU/mL); refrigerate immediately at 2–8 °C (35.6–46.4 °F).
Dosing Calculations:
- 250 IU = 10 units (0.10 mL)
- 500 IU = 20 units (0.20 mL)
- 1,000 IU = 40 units (0.40 mL)
High‑Dose Protocol (for Post‑Cycle Recovery or Severe Suppression)
| Week/Phase | Dose per Injection (IU) | Units (per injection) (mL) |
|---|---|---|
| Weeks 1–4 | 1,500 IU | 60 units (0.60 mL) |
| Weeks 5–8 | 2,000 IU | 80 units (0.80 mL) |
| Weeks 9–12 | 1,000 IU | 40 units (0.40 mL) |
Frequency: Inject 3 times weekly subcutaneously. High‑dose protocols (1,500–2,500 IU per injection) are used to reactivate testosterone production after prolonged anabolic steroid use or severe hypogonadotropic hypogonadism. After initial recovery, doses are typically reduced to maintenance levels (500–1,000 IU 3×/week).
