VIP is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
VIP (Vasoactive Intestinal Peptide) is a Neuropeptide, vasodilator, anti-inflammatory researched for vasodilation, bronchodilation, anti-inflammatory effects, neuroprotection, lung function improvement. For beginners, start at the lower end of the dosage range (50-100 mcg per spray or 200 mcg daily inhaled) and administer 4 times daily (nasal) or daily (inhaled) via intranasal spray or inhalation.
What Is VIP?
VIP (Vasoactive Intestinal Peptide) is a Neuropeptide, vasodilator, anti-inflammatory. Endogenous 28-amino acid neuropeptide produced in gut, pancreas, brain, and neuroendocrine tissues.
It is researched for its potential effects on vasodilation, bronchodilation, anti-inflammatory effects, neuroprotection, lung function improvement. The only peptide addressing vasodilation, bronchoprotection, AND neuroprotection through a single receptor family — but its 2-minute half-life makes practical delivery the primary challenge.
For beginners: This guide assumes no prior peptide experience. We'll cover everything from what VIP is to how to reconstitute, inject, and structure your first cycle.
How Does VIP Work?
Activates VPAC1 and VPAC2 class B G protein-coupled receptors, initiating adenylyl cyclase-cAMP cascade and CREB phosphorylation. Drives smooth muscle relaxation via calcium channel modulation, vasodilation through nitric oxide and prostacyclin production, neuroprotection via anti-inflammatory IL-10 induction, and enhanced insulin secretion via VPAC2 signaling.
Understanding the mechanism helps set realistic expectations about what VIP can and cannot do.
How Do You Get Started With VIP?
Step 1 — Source: Purchase VIP from a vendor with third-party Certificate of Analysis (COA) testing. This confirms purity (aim for 98%+) and rules out contamination.
Step 2 — Supplies: You'll need bacteriostatic water, insulin syringes (1mL/100-unit), alcohol swabs, and a clean workspace.
Step 3 — Reconstitute: Add BAC water to the VIP vial — use our peptide calculator for exact amounts. Let the water run down the side of the vial; never spray directly on the powder. Swirl gently.
Step 4 — Dose: Draw 50-100 mcg per spray or 200 mcg daily inhaled using the calculator's syringe unit conversion.
Step 5 — Inject: Clean the injection site with alcohol. Pinch a fold of abdominal fat and insert the needle at 45° for subcutaneous injection. Push the plunger slowly and hold for 5 seconds.

Dosage: Start at the lower end of 50-100 mcg per spray or 200 mcg daily inhaled. This lets you assess tolerance before committing to a full cycle.
Frequency: 4 times daily (nasal) or daily (inhaled) via intranasal spray or inhalation.
Duration: ongoing continuous therapy. Don't cut cycles short — many Neuropeptide, vasodilator, anti-inflammatory effects take weeks to fully manifest.
Off-cycle: Plan a 4-week break before starting another cycle.
What Side Effects Should Beginners Watch For?
Limited clinical data. Nasal irritation possible. Short half-life limits systemic toxicity. Well-tolerated in preliminary studies.
As a beginner, track everything — dose, time, injection site, and any effects (positive or negative). This data helps optimize future cycles.
What Are Common Beginner Mistakes?
Not using BAC water: Sterile water lacks the preservative that prevents bacterial growth. Always use bacteriostatic water.
Inconsistent dosing: Skipping doses or varying timing significantly reduces outcomes. Set a daily alarm.
Poor storage: Reconstituted VIP must stay refrigerated at 2-8°C. Leaving it at room temperature degrades the compound rapidly.
Buying cheap: Low-cost peptides without COA testing may be underdosed, contaminated, or mislabeled. Quality matters more than price.
Bottom Line for VIP Beginners
Start at the lower end of 50-100 mcg per spray or 200 mcg daily inhaled, dose 4 times daily (nasal) or daily (inhaled), cycle for ongoing continuous therapy, and track everything. Source from COA-tested vendors and follow proper reconstitution protocol.
