Oxytocin vs TriMix
A side-by-side research comparison of Oxytocin and TriMix across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Oxytocin | TriMix |
|---|---|---|
| Full name | Oxytocin (OXT) | TriMix (Papaverine + Phentolamine + Alprostadil) |
| Category | Sexual Health | Sexual Health |
| Status | FDA Approved | Compounded medication |
| Mechanism | Binds OXTR in social cognition brain regions (amygdala, nucleus accumbens) and reproductive organs. Modulates serotonin and dopamine in reward circuits. | Papaverine relaxes smooth muscle via PDE inhibition. Phentolamine blocks alpha-adrenergic receptors. Alprostadil (PGE1) directly stimulates cAMP production in cavernosal tissue. Together they produce reliable penile erection independent of arousal. |
| Molecular weight | 1,007 Da | Combination compound |
| Half-life | 3-5 min (IV) / 20-30 min (intranasal) | ~1-3 hours (local effect) |
| Bioavailability | Low (oral), Moderate (intranasal ~2-5%) | Direct intracavernosal: ~100% |
| Typical dose | 20-40 IU intranasal | 0.1-0.5 mL (titrated) |
| Frequency | As needed or daily | As needed, max 3x/week |
| Route | Intranasal or IV (obstetric) | Intracavernosal injection |
