Pal-AHK vs Oxytocin
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Pal-AHK is the palmitoylated form of the AHK-Cu copper tripeptide, created by attaching a palmitic acid chain to enhance skin penetration and lipid bilayer affinity. The palmitoyl modification significantly improves dermal bioavailability compared to unmodified AHK, making it particularly effective in anti-aging and hair growth formulations.
- 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.
- Half-Life
- Extended (lipid depot effect in stratum corneum)
- ~3–5 minutes (IV); ~30–60 minutes (intranasal, CNS effects persist longer)
- Admin Route
- Topical
- Intranasal, SubQ, IV
