Oxytocin vs KPV
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Oxytocin is a 9-amino acid neuropeptide produced in the hypothalamus with diverse roles in social bonding, trust, stress reduction, and sexual function. Exogenous administration is used therapeutically to improve social cognition, reduce anxiety, and enhance intimacy.
- KPV is a naturally occurring anti-inflammatory tripeptide derived from the C-terminal of alpha-MSH. It powerfully suppresses intestinal and systemic inflammation via melanocortin receptors, making it valuable for IBD, gut healing, and wound repair.
- Half-Life
- ~3–5 minutes (IV); ~30–60 minutes (intranasal, CNS effects persist longer)
- Short half-life (~15–30 minutes), but effects persist longer due to receptor-level anti-inflammatory cascades
- Admin Route
- Intranasal, SubQ, IV
- Oral, SubQ, Topical
