Overview
Gonadorelin is synthetic GnRH (gonadotropin-releasing hormone). It tells the pituitary to release LH and FSH — the signals that keep testosterone and sperm production running. It’s the lightest-touch option in HPTA-restart protocols.
Preparation
Reconstitute a 2 mg vial with 2 mL of bacteriostatic water (BAC) for a 1 mg/mL concentration. Use within a week once mixed.
| Vial | BAC | Concentration |
|---|---|---|
| 2 mg | 2 mL | 1 mg/mL |
Protocol
| Period | Dose | Units (@ 1 mg/mL) | Frequency |
|---|---|---|---|
| Weeks 1–2 | 50 mcg | 5 units (0.05 mL) | 2–3x/week |
| Weeks 3–4 | 100 mcg | 10 units (0.10 mL) | 2–3x/week |
| Weeks 5–8 | 100–150 mcg | 10–15 units (0.10–0.15 mL) | 2–3x/week |
Cycle
6–12 week cycles, typically as part of post-cycle therapy. Keep injections spaced out — GnRH works in pulses, not floods.
