What is VIP (Vasoactive Intestinal Peptide)?
Plain language first. The technical label stays, but it never stands alone.Overview
VIP (vasoactive intestinal peptide) is a natural 28-amino-acid signaling peptide found in the gut, lungs, and nerves. In plain terms: it relaxes blood vessels and airways and calms the immune system, which is why a nasal-spray form is used to try to quiet chronic inflammation, though it can lower blood pressure.
What it's used for
A nasal-spray peptide used to calm long-term inflammation and immune problems, popular in mold-illness protocols.
How does VIP (Vasoactive Intestinal Peptide) work?
What it does in the body, and where.VIP is a 28-amino-acid signalling peptide your gut, lungs, and nerves already produce. The nasal form is used off-label for chronic inflammatory conditions.
- 01It relaxes blood vessels and airwaysThe 'vasoactive' in the name, and its original identified function.
- 02It calms immune signallingShifting immune cells away from an inflammatory state, which is the basis for its use in chronic inflammatory response syndrome.
- 03The nasal route is deliberateVIP is destroyed almost immediately in the bloodstream, so it is sprayed rather than injected.
- 04Its main use is off-label and contestedThe mould-illness protocols it appears in are not accepted by mainstream medicine, and the peptide's evidence should not be confused with the protocol's.
Where this compound is thought to act.
What else is it used for?
Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.
- Sarcoidosis and lung inflammationInvestigational
- Chronic inflammatory response syndrome and mould illness, which is the main reason people seek it outResearch only
- Severe COVID lung failure, where a large trial found no benefitInvestigational
How much, and do you cycle it?
The range, and whether you take breaks.0.05 mg per dose, several daily. No established scheduleNo range
No published study has established how long to take this or whether a break is needed. Schedules quoted online come from vendors and forums, and different sources disagree.
How do I dose and price it?
Enter your vial and your dose. Pick a mix. We show the draw and the cost.The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.
VIP (Vasoactive Intestinal Peptide) is not injected
It is taken nasal spray.
How do you store it?
Before mixing, and after.Fridge after opening. Use within about 30 days.
Store sealed VIP (Vasoactive Intestinal Peptide) in the fridge. Once opened, keep it upright in the fridge and plan to finish it inside roughly 30 days. Keep it out of light and do not freeze the liquid.
What are the side effects and cautions?
Known cautions and warnings for this compound.Who should avoid it
- Low blood pressure, since it widens blood vessels
- No formal contraindications established
Stop and get help
- Feeling faint or very dizzy, which can signal a blood-pressure drop
- Signs of an allergic reaction such as face or throat swelling, hives, or trouble breathing
Common effects
- Diarrhea
- A drop in blood pressure, which is the main known effect
- In a large COVID trial it was stopped for lack of benefit, not for safety problems

What these words mean
- Titrate
- Starting at a low dose and increasing it slowly over time so your body adjusts and side effects stay mild.
- Subcutaneous
- An injection just under the skin, into the fat layer, usually with a short, thin insulin needle.
- Intramuscular (IM)
- An injection into a muscle, using a longer needle.
- Reconstitution
- Mixing a powdered peptide with liquid (bacteriostatic water) so it can be drawn into a syringe.
- Bacteriostatic water
- Sterile water with a tiny amount of preservative, used to mix powdered peptides.
- Concentration
- How strong the mixed peptide is, in milligrams per milliliter (mg/mL). More water makes it weaker; less water makes it stronger.
- Units (on the syringe)
- The marks on an insulin syringe. 100 units equals 1 mL. They measure how much liquid you draw, not the dose in milligrams.
- mcg and mg
- Units of dose. 1 milligram (mg) equals 1,000 micrograms (mcg).
- GLP-1
- A natural gut hormone that lowers appetite and blood sugar. Drugs that copy it, like semaglutide, are used for weight loss.
- Growth hormone secretagogue
- A compound that nudges your body to release more of its own growth hormone, rather than injecting the hormone itself.
- Half-life
- How long a compound stays active in your body. A longer half-life means you inject less often.
- Peptide vs small molecule
- A peptide is a short chain of amino acids. A few items here (like MK-677 or methylene blue) are small molecules, not true peptides, but people use them the same way.
- Research only
- No approved dose or use in people. Sold for research and not reviewed by the FDA for safety or quality.
- Investigational
- Still being tested in clinical trials and not yet approved or legally sold for general use.
- Banned in drug-tested sport
- Prohibited by the World Anti-Doping Agency (WADA); using it can disqualify a competing athlete.
