VIP (Vasoactive Intestinal Peptide) Dosage Chart
VIP is a 28-amino-acid neuropeptide with pleiotropic immune, vasoregulatory, and neuroendocrine functions (Delgado & Ganea, Amino Acids 2013). Because its systemic half-life is only a couple of minutes, research protocols almost always use intranasal delivery rather than injection.

Dosage Protocols
Each row reflects a common research protocol variant. These are reference ranges derived from published literature and community research — not medical guidance.
Protocol 1
Standard Intranasal Research Protocol
Dose
50mcg per spray, 1 spray up to 4 times daily
Duration
4-12 weeks
Mirrors the intranasal VIP protocol used in chronic inflammatory research. Start low and titrate frequency upward as tolerated.
Protocol 2
Conservative Entry Protocol
Dose
50mcg once daily (single actuation)
Duration
1-2 weeks before increasing
VIP is a vasodilator; a single daily actuation lets researchers assess blood-pressure and flushing response before adding doses.
Protocol 3
Maintenance Protocol
Dose
50mcg 1-2 times daily
Duration
Ongoing (cycled)
Reduced-frequency dosing after an initial titration window.

Handling Notes
VIP is fragile. Keep the lyophilized vial frozen (-20°C) until use; refrigerate the reconstituted nasal solution at 2-8°C and use within the compounder's stated window. Protect from light and heat.
Research Considerations
Cautions
- VIP is a potent vasodilator and can lower blood pressure and cause flushing; assess response before increasing frequency.
- VIP is a research compound not approved for human use. Source only COA-verified material.
- Most protocols derive from a specific chronic-inflammatory research context and are not validated for general use.
