Gonadorelin vs Kisspeptin-10 (HPG Axis)
A side-by-side research comparison of Gonadorelin and Kisspeptin-10 (HPG Axis) across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Gonadorelin | Kisspeptin-10 (HPG Axis) |
|---|---|---|
| Full name | Gonadorelin (GnRH Analog) | Kisspeptin-10 (Metastin 45-54) |
| Category | Hormone Replacement | Hormone Replacement |
| Status | FDA Approved | Research compound |
| Mechanism | Binds GnRH receptors on pituitary gonadotrophs to stimulate LH and FSH release, maintaining testicular/ovarian function and natural sex hormone production. | Binds KISS1R (GPR54) receptors on GnRH neurons in the hypothalamus, triggering pulsatile GnRH release. This cascades to LH/FSH secretion from the pituitary, maintaining the natural feedback loop. |
| Molecular weight | 1182.39 Da | 1302.5 Da |
| Half-life | ~10-40 minutes | ~28 minutes (IV); ~4 hours (SubQ) |
| Bioavailability | ~90% subcutaneous | ~90% (subcutaneous) |
| Typical dose | 100-500 mcg | 100-400 mcg |
| Frequency | 2-3x per week or pulsatile | 1-2x daily |
| Route | Subcutaneous injection | Subcutaneous injection |
