VIP (Vasoactive Intestinal Peptide)

Published · Researched 2026-09-21

Overview

Vasoactive intestinal peptide (VIP) is an endogenous 28-amino-acid neuropeptide (secretin/glucagon superfamily, first isolated 1970 by Said and Mutt), acting via VPAC1/VPAC2 receptors. It is one of the most pleiotropic immune-neuro signaling molecules known: it downregulates TNF-α, IL-6, IL-12, upregulates anti-inflammatory IL-10, modulates T-cell motility/cytokine production, and shows direct antimicrobial activity against various pathogens. Its Achilles' heel is a ~2-minute plasma half-life, which is why therapeutic interest centers on stabilized analogs and local (nasal) delivery. VIP is best known in biohacker culture through the CIRS (chronic inflammatory response syndrome) community's VIP nasal-spray protocol and COVID-era aviptadil research.

Social standing

• Instagram: David Albanese's (@realdavidalbanese, RIPD.FIT) "PEPTIDE CHEAT SHEET — PART 3" carousel (Dec 2025, 8.1K likes, 120 comments) includes a VIP immunity-peptide slide: 5 mg vial, 5 ml BAC water, 50 mcg (5 units) AM/PM daily, 8 weeks on/off — placing VIP alongside KPV in the immunity stack. Beyond this, VIP's social presence is mostly educator-level; dedicated owner-discussion is thin.
• CIRS community layer (non-Meta but real): Shoemaker-protocol CIRS groups have discussed VIP nasal spray for years for neurocognitive recovery — the strongest real-world owner base, though largely off the Meta platforms surveyed.
• Recurring praise: endogenous human molecule (familiarity trust); broad immune + circadian + neuro coverage; the nasal route.
• Recurring complaints/failure modes: short half-life makes dosing rationale shaky; expensive per dose; confusion with COVID-era aviptadil IV use vs. gray-market nasal/injectable vials.
• Representative quotes: none with attributable peer-owner provenance on Meta platforms beyond the cheat-sheet dosing above (reported as observed content, not advice).

Social validation

Tier 2 — one strong independent IG source (Albanese cheat sheet, 8.1K likes) plus the long-standing CIRS patient-community usage (off-platform). Downgraded from Tier 1: no two independent Meta-platform sources with owner discussion; Threads/FB Group chatter is sparse.

Key specs table

Pricing

• Gray-market (observed 2026-09-20): research-grade 6 mg vial listings exist (suaway.com); exact current USD price UNVERIFIED. Typical observed range in 2025–2026 vendor listings ~$60–90 per 5–6 mg vial — UNVERIFIED, do not treat as quoted.
• Facebook Marketplace: no used listings observed — say so plainly (none found).

What's included / what's needed

Vial: 5–6 mg lyophilized powder in sealed flip-top vial. Needed: bacteriostatic water, insulin syringes (injectable use) or sterile nasal-spray bottle if used nasally (standard kit). Compounded CIRS nasal spray comes ready-to-use from 503A pharmacies.

Support reality

Gray-market VIP flows through standard research vendors with COAs; the CIRS community (Shoemaker-certified practitioners) is the only organized user base, with compounding-pharmacy supply and practitioner oversight — a much stronger support reality than typical research peptides, but only for those inside that ecosystem.

Community verdict

VIP is the insider's immune peptide — loved by the CIRS crowd and featured on a major cheat sheet, but barely discussed as a product anywhere else. The endogenous-molecule trust factor is real, the half-life problem is real too, and most buyers can't distinguish the nasal-spray protocol from injectable vials. Status: niche-legit, not mainstream.

Regulatory & safety status

Not FDA-approved for general human use; aviptadil (VIP analog) has been studied for pulmonary conditions/COVID under trial/expanded-access settings — not an approval. Compounded VIP nasal spray exists via 503A pharmacies by prescription within the CIRS ecosystem (compounded, not FDA-approved). Gray-market VIP vials are research chemicals not for human use. Safety signals (observed): flushing/hypotension are the known VIP pharmacology risks (vasodilation); short half-life limits systemic exposure but also efficacy. Never imply FDA approval.
