VIP
Summary
Humanin is a mitochondria-derived peptide (MDP) encoded in the 16S rRNA region of the mitochondrial genome. It protects neurons and other cells from apoptosis, improves insulin sensitivity, and declines significantly with age. HNG (S14G-Humanin) is a synthetic analog with 1000x greater potency.
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.
