Tripeptide-29- Summary
- VIP is a 28-amino acid neuropeptide with profound anti-inflammatory, vasodilatory, and immunomodulatory effects. It plays a critical role in gut motility, circadian rhythm, and immune tolerance. Used therapeutically for CIRS (Chronic Inflammatory Response Syndrome), MCAS, and inflammatory conditions.
- Tripeptide-29 is a pro-collagen cosmetic peptide composed of proline, hydroxyproline, and glycine — the core repeating unit of collagen. Applied topically, it signals dermal fibroblasts that collagen degradation has occurred, triggering compensatory new collagen synthesis.
- Half-Life
- ~2 minutes in plasma (rapidly degraded by peptidases); intranasal delivery may extend local CNS effects
- Not applicable (topical)
- Admin Route
- Intranasal, SubQ, IV
- Topical
