VIP // CIRS Protocol Essential
28-amino acid neuropeptide that is the final step in the Shoemaker CIRS (Chronic Inflammatory Response Syndrome) recovery protocol. VIP regulates pulmonary arterial pressure, modulates immune response, supports blood-brain barrier integrity, and normalizes inflammatory cytokines disrupted by mold illness and biotoxin exposure.
Multi-system immune normalization.
VIP is an endogenous neuropeptide with receptors throughout the body — lungs, brain, gut, and immune system. In CIRS patients, VIP levels are chronically depleted. Replacement therapy normalizes the downstream dysfunction.
Nasal delivery, four times daily.
VIP is administered intranasally per the Shoemaker CIRS protocol. It is the final step — Step 12 — meaning all prior remediation, binder therapy, and upstream corrections must be completed first. VIP without completing earlier steps can worsen outcomes.
The Shoemaker CIRS framework.
Dr. Ritchie Shoemaker's work on Chronic Inflammatory Response Syndrome established VIP as the capstone of biotoxin illness recovery. His research demonstrated that ~24% of the population carries HLA-DR genotypes that prevent adequate clearance of biotoxins from mold, Lyme, and other environmental exposures.
In CIRS patients, endogenous VIP levels are chronically depleted — measured via blood draw. This VIP deficiency drives pulmonary artery hypertension, impaired exercise tolerance, cognitive dysfunction, and a cascade of inflammatory biomarker abnormalities including elevated TGF-beta1, C4a, and MMP-9.
VIP replacement therapy — after completing all upstream Shoemaker protocol steps — has shown improvements in pulmonary function, exercise capacity, cognitive performance, and normalization of CIRS-specific biomarkers. The intranasal route provides direct CNS access for neuroinflammatory effects.
CIRS protocol compounds.
| Compound | CIRS Role | Route | Timing | Notes |
|---|---|---|---|---|
| VIP | Step 12 — Capstone | Intranasal | After Steps 1–11 | Normalizes VIP deficiency |
| BEG Spray | Step 7 — MARCoNS | Intranasal | After remediation | Biofilm/MRSA nasal |
| Cholestyramine | Step 2 — Binder | Oral | Early protocol | Biotoxin binding |
| LL-37 | Antimicrobial support | SubQ | Adjunct | Biofilm penetration |
What to watch for.
VIP's side effect profile is manageable with proper protocol adherence. Baseline blood work before starting and periodic monitoring during use is essential.
- Nasal congestion or irritation
- Transient hypotension (vasodilator effect)
- Diarrhea (GI VIP receptors — dose-dependent)
- Flushing (vasodilation)
- Risk of worsening if used before completing Steps 1–11
- Monitor lipase — rare pancreatic effects reported
- VIP level (baseline — confirm deficiency)
- VEGF (vascular endothelial growth factor)
- TGF-beta1
- C4a complement
- MMP-9 (matrix metalloproteinase-9)
- MSH (alpha-melanocyte stimulating hormone)
- Lipase (pancreatic monitoring)
- ADH / osmolality
- Only use after completing Shoemaker Steps 1–11
- LL-37 for antimicrobial support during CIRS protocol
- BPC-157 for GI support (VIP can cause GI effects)
- Do NOT combine with vasodilators without monitoring
- Requires CIRS-literate physician oversight
- Not a standalone peptide — context-dependent use only
- Compounded nasal spray: refrigerate at 2–8°C
- Use within expiration from compounding pharmacy
- Protect from light
- Do not freeze
- Must be obtained through compounding pharmacy with prescription
Compounds that complement VIP.
The CIRS capstone — but context is everything.
VIP is not a standalone peptide. It's Step 12 of the Shoemaker Protocol for a reason — using it without completing remediation, binder therapy, MARCoNS treatment, and hormone correction can actively worsen CIRS outcomes. But when used correctly, after all upstream steps are complete, VIP replacement normalizes the pulmonary, neurological, and immunological dysfunction that defines biotoxin illness. This is a prescription compound requiring a CIRS-literate physician — not something to self-administer. Confirm VIP deficiency via blood draw first, track all CIRS biomarkers, and have physician oversight throughout.
