VIP
Not FDA ApprovedAlso: Vasoactive Intestinal Peptide, Aviptadil
Vasoactive Intestinal Peptide (VIP) is a naturally occurring neuropeptide with a 28-amino acid sequence that has potent anti-inflammatory, immunomodulatory, and neuroprotective properties. It binds to VPAC1 and VPAC2 receptors, affecting immune function, vascular tone, and neurological health. VIP is being studied for applications in conditions such as chronic inflammatory response syndrome, pulmonary disorders, and COVID-19 related ARDS. Although VIP is not approved by the FDA, it has received Fast Track designation for specific indications, but users should be cautious of potential side effects like nausea and blood pressure changes.
