What Is VIP (Vasoactive Intestinal Peptide)? Identity and Research Context

VIP is searched by name far more often than it is explained accurately. This overview keeps to what can be stated plainly and checked against public records: what VIP is as a molecule, and the research field it belongs to. It does not make claims about what it does.

What VIP is

VIP (vasoactive intestinal peptide) is a synthetic 28-amino-acid peptide. Its identity is publicly checkable: PubChem CID 53314964, CAS 37221-79-7, molecular formula C147H237N43O43S, and an average molecular weight of about 3,326 g/mol.

What research areas is VIP associated with?

Because VIP belongs to the secretin and glucagon peptide superfamily, in the scientific literature it is discussed within neuropeptide research and the study of that peptide family. That names the research area the molecule sits in; it is not a statement about any effect, result, dose, or use. Naming a field of study is not the same as making a claim.

Why we describe it this way

Most pages selling a compound like this lead with what it supposedly does. We do not: these products are sold strictly for laboratory research, so outcome and use claims are not appropriate, and what actually separates suppliers is whether the material is what the label says. That is a documentation question, and we answer it in public with a third-party certificate for every lot.

Check the lot yourself

Look up any lot on our public register, read our guide on how to read a COA, or see what >98% purity actually means across every lot we publish. Browse the product itself: VIP. More identity guides: Sermorelin and Tesamorelin.
