VIP peptide

VIP 5mg – Premium Vasoactive Intestinal Peptide for Immune Modulation, Neuroendocrine & Anti-Inflammatory Research | Advanced 28-Amino Acid Neuropeptide to Support Gut Health, Vasodilation, T-Cell Balance & Cellular Repair Insights
Elevate your immune, gut, and neuroendocrine research with VIP 5mg (Vasoactive Intestinal Peptide) from Ion Peptide, the high-purity synthetic 28-amino acid neuropeptide designed for advanced laboratory studies on immune regulation, anti-inflammatory pathways, vasodilation, and gastrointestinal function. As a potent modulator of both innate and adaptive immunity, VIP balances Th1/Th2 responses, promotes smooth muscle relaxation, and supports tissue repair — making it a versatile research tool for investigating chronic inflammation, gut barrier integrity, pulmonary health, and overall homeostasis.
Premium Product Overview
VIP (Vasoactive Intestinal Peptide) is supplied as a stable lyophilized acetate salt in convenient 5mg vials for easy reconstitution.
This 28-amino acid peptide belongs to the glucagon/secretin superfamily, with the sequence H-His-Ser-Asp-Ala-Val-Phe-Thr-Asp-Asn-Tyr-Thr-Arg-Leu-Arg-Lys-Gln-Met-Ala-Val-Lys-Lys-Tyr-Leu-Asn-Ser-Ile-Leu-Asn-NH₂. Molecular weight is approximately 3,326 Da (human/porcine/rat form). Manufactured at ≥99% purity (third-party HPLC & MS verified), VIP 5mg provides researchers with a bioactive, multi-functional peptide for precise investigations into VPAC1/VPAC2 receptor signaling, cAMP elevation, and systemic immunomodulation.
Key Research Benefits of VIP 5mg

Immune Modulation & Anti-Inflammatory Effects: Balances Th1/Th2 pathways, reduces excessive inflammation, and enhances regulatory T-cell activity in models of autoimmune and chronic inflammatory conditions.
Gut Health & Barrier Support: Promotes intestinal epithelial integrity, regulates water/electrolyte secretion, and supports mucosal repair in gastrointestinal research.
Vasodilation & Smooth Muscle Relaxation: Induces potent vasodilation, bronchodilation, and relaxation of smooth muscle in pulmonary, cardiovascular, and GI systems.
Neuroendocrine & Cellular Repair: Influences hormone release, circadian rhythms, and tissue remodeling while providing neuroprotective and anti-fibrotic insights.
Synergistic Potential: Frequently studied with other immune or regenerative peptides (e.g., Thymosin Alpha-1, BPC-157, or GHK-Cu) for comprehensive anti-inflammatory and repair outcomes.

Researchers value VIP as the “master immunomodulatory neuropeptide” for its broad regulatory effects across immune, gut, and vascular systems.

Quality Assurance & Usage in Research
Sourced exclusively for laboratory research with USA-verified COAs. VIP 5mg reconstitutes easily with bacteriostatic water. Store lyophilized vials at -20°C and reconstituted solutions refrigerated.
Common Research Protocols (for reference only): Typical subcutaneous doses in studied models range from 0.1–2 mg per injection, often administered 3–5 times weekly. Some protocols explore daily low-dose administration or nasal delivery models. Always follow precise reconstitution and institutional guidelines.
Important Research Considerations
VIP 5mg is a potent research chemical intended strictly for laboratory use only. It has been extensively studied for its anti-inflammatory and immunomodulatory properties with a generally favorable safety profile in controlled settings. Common observations may include mild flushing, headache, or transient gastrointestinal effects. It is not approved by regulatory agencies for human therapeutic, cosmetic, or performance use. Prioritize proper protocols, biomarker monitoring (cytokine profiles, immune cell markers, gut integrity), and consult qualified professionals for any application beyond strict lab research.
