VIP (vasoactive intestinal peptide) is a 28-amino-acid neuropeptide of the secretin/glucagon peptide family, originally isolated from mammalian intestinal tissue and used in vitro and in animal models as a VPAC1 and VPAC2 receptor agonist. Investigators reference it in vasodilation assays, gut-brain axis studies, and neuroimmune signaling work.
Real Peptides supplies VIP as a lyophilized 5mg multi-dose vial with no added excipients. Every batch is submitted to an independent analytical laboratory, and the certificate of analysis for the current lot is published in the lab results section of this site, so identity and purity figures can be reviewed before purchase. Orders ship from Florida and California facilities within 24 hours. This material is sold strictly for laboratory research use and is not a drug, supplement, or cosmetic.

VIP (Vasoactive Intestinal Peptide) is the lab favorite when you need a dependable reagent for blood-vessel relaxation, neuroimmune communication, and gut-brain axis assays. Each 5 mg vial delivers a ready-to-use peptide that reliably triggers VIP receptor pathways in cell cultures and animal models—no extra additives, no guesswork. HPLC-verified at ≥ 99% purity, and endotoxin-screened (< 0.1 EU/mg), VIP ensures crisp, reproducible results every time.
What Is VIP Peptide?
VIP is a 28-amino-acid neuropeptide that naturally regulates blood-vessel tone, immune responses, and digestive-tract signaling. In research, VIP peptide is used to explore vasodilation, neuroimmune interactions, and enteric-nervous-system pathways under controlled lab conditions.
Why Choose VIP?
Choose VIP when you want a versatile peptide that covers vascular, neural, and immune assays in one reagent. Its reliable activation of VPAC receptors delivers reproducible vasodilation, cAMP signaling, and cytokine modulation—so you can compare compounds, map pathways, or screen anti-inflammatory agents with confidence.
What Sets VIP Apart?
Unlike single-pathway agonists, VIP offers multi-system utility—simultaneously engaging vascular, neuronal, and immune cells. Its robust receptor specificity and rapid, dose-dependent action make VIP the go-to peptide for integrated studies of blood-flow regulation, gut-brain communication, and neuroimmune balance.
