A side-by-side research comparison of Kisspeptin-10 and Oxytocin across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Kisspeptin-10 | Oxytocin |
|---|---|---|
| Full name | Kisspeptin-10 (Metastin 45-54) | Oxytocin (OXT) |
| Category | Sexual Health | Sexual Health |
| Status | Research compound | FDA Approved |
| Mechanism | Binds KISS1R on GnRH neurons, stimulating GnRH pulsatile release for LH/FSH secretion. Also enhances limbic sexual arousal circuits. | Binds OXTR in social cognition brain regions (amygdala, nucleus accumbens) and reproductive organs. Modulates serotonin and dopamine in reward circuits. |
| Molecular weight | 1,302 Da | 1,007 Da |
| Half-life | 4-6 min (IV) / 20-30 min (SubQ) | 3-5 min (IV) / 20-30 min (intranasal) |
| Bioavailability | High (IV/SubQ) | Low (oral), Moderate (intranasal ~2-5%) |
| Typical dose | 1-10 nmol/kg | 20-40 IU intranasal |
| Frequency | Single dose or daily | As needed or daily |
| Route | IV or Subcutaneous | Intranasal or IV (obstetric) |
