Disclaimer: This curve is a simplified first-order exponential decay model. Actual pharmacokinetics vary based on injection site, individual metabolism, body composition, and other factors. Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.

Note: Intranasal administration only. Used as the final step (step 11) in the Shoemaker CIRS protocol. Must address prior steps (cholestyramine, MARCoNS eradication, etc.) before starting VIP. Each dose is 4 sprays at 50 mcg per spray (200 mcg total per dose). Do not start VIP if VCS test is still failing or MARCoNS is still present.

About VIP (Vasoactive Intestinal Peptide)

VIP (Vasoactive Intestinal Peptide) is a 28-amino-acid neuropeptide produced throughout the body, with high concentrations in the gut, lungs, and brain. It acts as both a neurotransmitter and an immune modulator. In the context of CIRS (Chronic Inflammatory Response Syndrome) caused by mold and biotoxin exposure, VIP is used intranasally to reduce persistent inflammation, normalize dysregulated cytokines like TGF-beta and MMP-9, restore regulatory T-cell function, and improve grey matter volume in the brain. It is the final therapeutic step in Dr. Ritchie Shoemaker's published CIRS treatment protocol, used only after all preceding interventions have been completed.
