Beginner setup
Vial sizes vary by vendor. Smaller bottles are usually 3 mL; larger bottles are often 10 mL. Match the label on the vial you actually bought, then use the calculator below if you need to adjust.
Vial strength 10 mg
Bottle format often 3 mL
BAC water 3 mL
Concentration 3.33 mg/mL
Overview
HMG (human menopausal gonadotropin) provides both FSH and LH activity — FSH drives sperm production, LH drives testosterone. It’s the fertility-workhorse companion to HCG in HPTA-restart protocols.
Preparation
Reconstitute a 75 IU vial with 3 mL of bacteriostatic water (BAC) for a 25 IU/mL concentration. Note the volume: a full 75 IU dose is 3 mL, which needs a 3 mL syringe or three separate 1 mL injections.
| Vial | BAC | Concentration |
|---|---|---|
| 10 mg | 3 mL | 3.33 mg/mL |
Protocol
| Period | Dose | Units (@ 3.33 mg/mL) | Frequency |
|---|---|---|---|
| Weeks 1–12 | 75 IU (0.15 mg) | 3.0 mL (300 units) — split 3 × 1 mL | 3x/week |
| Weeks 13–16 (optional) | 75 IU (0.15 mg) | 3.0 mL (300 units) — split 3 × 1 mL | 3x/week |
Cycle
12–16 week protocols, typically combined with HCG. The 3 mL per dose volume is the defining practical detail — plan syringes accordingly.
