GnRH agonist — HPG-axis support during TRT, fertility maintenance. Pulsatile dosing.
- Half-life
- 6 min
- Out of system
- ~1 h
- Route
- Subcutaneous
- Level
- Advanced
Very short-acting — protocols dose 1–2× a day. After the last dose, roughly 97% has cleared in ~1 h (five half-lives) — the window that matters for washouts, bloodwork and surgery.
What Gonadorelin (GnRH) is used for
- Pulsatile GnRH — keeps the HPG axis active during TRT
- Supports fertility and endogenous testosterone
How it's typically used
Research range: ~100 mcg subcutaneous every other day (or pulsatile).
What to watch for
- Very short half-life — needs frequent/pulsatile dosing
- Continuous (non-pulsatile) use paradoxically suppresses
- Prescription-only; clinician guidance advised
