VIP (Vasoactive Intestinal Peptide): A Research Overview
VIP, or vasoactive intestinal peptide, is a signalling molecule with an unusually wide reach across the body's systems, which is why it appears in such diverse areas of research. This overview explains what VIP is and what the research describes — strictly for educational and research context.
What VIP actually is
VIP is a 28-amino-acid neuropeptide belonging to the secretin/glucagon peptide family. It is produced throughout the nervous system and gut and acts through receptors (VPAC1 and VPAC2) found on a wide range of tissues, which is why its effects are so broad.
Why it's studied so widely
VIP's name comes from its vasodilatory (blood-vessel-relaxing) activity, but research interest extends well beyond that. It is studied for roles in immune regulation and anti-inflammatory signalling, smooth-muscle relaxation, circadian-rhythm regulation in the brain's master clock, and neuroprotection. Few peptides touch as many systems.
What the research explores
Research models have examined VIP's anti-inflammatory and immunomodulatory effects in particular, alongside its vascular and neurological roles. Its ability to dampen inflammatory signalling has made it a compound of interest in immunology research. As with most peptides in this space, much of the work is preclinical and early-stage.
Handling and preparation
VIP is supplied as a lyophilised powder, kept cold and protected from light, then reconstituted for laboratory work. Our reconstitution guide and the on-site peptide calculator walk through preparing a solution and calculating concentration. Every batch ships with a per-batch Certificate of Analysis so identity and purity can be verified.
Important context
This article summarises published research for educational purposes only. VIP is supplied strictly for laboratory and research use only — not for human or veterinary use, consumption, or injection. Nothing here is medical advice, a recommendation, or a dosing protocol. The mechanisms described are research findings, not approved claims, and researchers are responsible for safe handling and compliance with applicable laws.
The bottom line
VIP is a broadly-acting neuropeptide studied across vascular, immune, circadian and neurological systems, with particular research interest in its anti-inflammatory signalling. As with everything we carry, our VIP comes with full batch documentation and a verifiable COA.
