VIP Research Peptide

VIP (Vasoactive Intestinal Peptide) is a 28-amino-acid neuropeptide of the secretin/glucagon family, examined in the literature across VPAC1/VPAC2 receptor signalling, immunomodulation, circadian regulation in the suprachiasmatic nucleus, and smooth-muscle models.

VIP is synthesis-intensive and oxidation-sensitive — a compound where supplier quality shows immediately in the analytics. Our material is independently verified to ≥99% purity by HPLC with MS identity confirmation, and ships with a batch-specific COA.
