Vasoactive Intestinal Peptide (VIP)

THE MULTI-SYSTEM HEALER

VIP, Aviptadil, PHM27

VIP is a versatile 28-amino-acid neuropeptide that acts as a master regulator of inflammation throughout your body. It protects the brain, heals the gut, supports lung function, and calms overactive immune responses. It's particularly effective for Chronic Inflammatory Response Syndrome (CIRS), mold illness, and complex multi-system inflammatory conditions.
