Oxytocin vs DSIP
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.
- DSIP is an endogenous neuropeptide originally isolated from rabbit cerebrospinal fluid that induces delta-wave (deep) sleep. It also modulates stress response, cortisol regulation, and LH secretion, making it valuable for sleep optimization and stress management.
- Half-Life
- ~3–5 minutes (IV); ~30–60 minutes (intranasal, CNS effects persist longer)
- ~30–60 minutes; however downstream sleep effects last 4–6 hours
- Admin Route
- Intranasal, SubQ, IV
