VIP
Summary
GHK is the natural tripeptide (Gly-His-Lys) released from human albumin that activates tissue remodeling, collagen synthesis, and anti-aging gene expression. The copper-free form is the biological signaling molecule; it chelates copper in tissue to form GHK-Cu but also has independent biological activity.
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.
Half-Life
Extremely short as free peptide; tissue binding extends local effects
~2 minutes in plasma (rapidly degraded by peptidases); intranasal delivery may extend local CNS effects
Admin Route
SubQ, Topical, Oral
Intranasal, SubQ, IV
