Kisspeptin-10 vs Tadalafil
A side-by-side research comparison of Kisspeptin-10 and Tadalafil across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Kisspeptin-10 | Tadalafil |
|---|---|---|
| Full name | Kisspeptin-10 (Metastin 45-54) | Tadalafil (Cialis) |
| Category | Sexual Health | Sexual Health |
| Status | Research compound | FDA-approved prescription |
| Mechanism | Binds KISS1R on GnRH neurons, stimulating GnRH pulsatile release for LH/FSH secretion. Also enhances limbic sexual arousal circuits. | Selectively inhibits phosphodiesterase type 5 (PDE5), preventing cGMP breakdown in smooth muscle. This enhances nitric oxide signaling for vasodilation in penile, pulmonary, and prostate tissue. |
| Molecular weight | 1,302 Da | 389.40 Da |
| Half-life | 4-6 min (IV) / 20-30 min (SubQ) | ~17.5 hours |
| Bioavailability | High (IV/SubQ) | ~36% oral |
| Typical dose | 1-10 nmol/kg | 2.5-5 mg daily or 10-20 mg as needed |
| Frequency | Single dose or daily | Daily or on-demand |
| Route | IV or Subcutaneous | Oral tablet |
