DSIP vs SNAP-8
Side-by-side comparison of key properties, dosing, and research.
- Summary
- 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.
- SNAP-8 is a synthetic octapeptide cosmetic ingredient that reduces the depth of expression lines and wrinkles by competitively inhibiting the SNARE complex involved in acetylcholine release at neuromuscular junctions, providing a topical 'Botox-like' effect.
- Half-Life
- ~30–60 minutes; however downstream sleep effects last 4–6 hours
- N/A — topical application; local effect duration depends on formulation
- Admin Route
- SubQ, IV, Intranasal
- Topical
