Description
VIP (Vasoactive Intestinal Peptide) – 10mg (Lyophilized Peptide in 3ml Vial) – For Research Use Only
VIP (Vasoactive Intestinal Peptide) is a naturally occurring neuropeptide and immunomodulator studied for its effects on vasodilation, smooth muscle relaxation, immune regulation, and neuroprotection. It plays a crucial role in gastrointestinal, pulmonary, and central nervous system signaling.
In research models, VIP has shown promise in areas such as inflammatory and autoimmune disease, lung function, and gut-brain axis modulation.

VIP Nasal Spray peptide Details
VIP Nasal Spray — Research Grade | Pre-Formulated Liquid Solution
This nasal spray formulation delivers VIP (Vasoactive Intestinal Peptide) as a pre-formulated, sterile liquid solution for research use. No reconstitution is required — the product arrives ready for laboratory application via the nasal spray delivery format.
VIP is a 28-amino acid neuropeptide found throughout the central and peripheral nervous systems, gastrointestinal tract, and immune tissues. Research has explored its roles in neuroimmune regulation, bronchodilation, circadian rhythm control (via suprachiasmatic nucleus), anti-inflammatory signaling, and vasodilation in preclinical models.
Nasal spray format note: This product is supplied as a metered-dose nasal spray bottle. Intranasal VIP delivery has been investigated in preclinical research for CNS access and neuroimmune modulation applications. The nasal format is explored as a non-invasive route for investigating VIP's central effects. All use is strictly for laboratory and research purposes only.
⚠️ For Research Use Only — Not for human consumption. Requires 2nd Day Air or Next Day Air shipping (no ground shipping available).
VIP Nasal Spray peptide Scientific Research
1. Neuroimmune Signaling and Inflammatory Regulation
VIP is used to study cytokine modulation in immune cells including T lymphocytes, macrophages, and dendritic cells. It is involved in downregulating pro-inflammatory mediators (e.g., TNF-α, IL-6) and upregulating anti-inflammatory cytokines like IL-10 in in-vitro and animal models.
2. Vascular and Smooth Muscle Physiology
Through VPAC1/VPAC2 activation, VIP induces relaxation in smooth muscle tissues such as airway, vascular, and gastrointestinal smooth muscle. These properties are often evaluated in cardiovascular or pulmonary research for assessing vasodilatory and bronchodilatory mechanisms.
3. Epithelial Barrier Integrity
VIP has been studied in gut and respiratory epithelial models where it enhances tight-junction protein expression, aiding in barrier maintenance and regulating permeability. This is relevant in preclinical studies on inflammatory bowel disease (IBD) and respiratory epithelial dysfunction.
4. Neuroprotective and Synaptic Maintenance Studies
VIP has been shown to support neurotrophic factor expression and synaptic homeostasis. It is used in neurodegenerative models and CNS-focused research to evaluate neuroplasticity, synapse maintenance, and neuron-glia signaling.
5. Anti-Fibrotic Pathway Exploration
Preclinical studies indicate that VIP downregulates fibrotic markers in lung and cardiac models, making it useful in research investigating peptide-regulated fibrotic and remodeling processes in chronic disease contexts.

Handled correctly, stability holds
All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.
Store vials in a cool, dry place away from heat and direct sunlight.
For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.
Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.
Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.
Frequently Asked Questions
PRODUCT & PURITY
This product is offered for laboratory and research use only. It is not intended for human consumption, medical use, therapeutic use, or veterinary use.
Yes, all of our products are sterile and sealed with a sterility plug and safety cap.
Our products undergo quality control internally at our lab and then 3rd party tested at Bioviridian (at their Texas facility) prior to shipment. All of our COA's are then posted on our site immediately upon receipt.
99% or higher. Period. The expected purity is listed on the individual product page or Certificate of Analysis, when available.
No. We are a manufacturing company and because these products are sold for research purposes only, we do not provide dosing, administration, or medical-use guidance.
Unless specifically stated otherwise, these products are not approved by the U.S. Food and Drug Administration for therapeutic or diagnostic use.
STORAGE & STABILITY
As a lyophilized powder, peptides are stable. Delays in shipments up to 7 days will have zero to minimal impact on efficacy of peptides. Most precautionary efforts must be made to maintain temperature consistency once reconstituted.
Store the product according to the storage recommendations provided on the label or accompanying documentation in your shipment. Proper storage helps maintain product integrity during its shelf life. Most peptides have an expiration date of 2 years if kept unreconstituted (lyophilized powder).
SHIPPING
Shipping times vary based on your location and the shipping method selected at checkout. We offer shipping options between 1 and 5 days.
No.
Once your order is processed, you will receive a shipping confirmation email with tracking information.
ORDERS
