WHOLESALE KIT — IMPORTANT ORDER INFORMATION

This is a wholesale 10-vial program. Kits are fulfilled directly through our international manufacturing and fulfillment network rather than from standard retail inventory, allowing us to offer genuine bulk pricing.

Please review the following before adding a kit to your cart:

Longer processing time: Wholesale kit orders may require 5–10 business days of processing before carrier transit begins. This is longer than standard single-vial orders.
Ships internationally: Wholesale kits are fulfilled from Hong Kong and shipped worldwide. International transit and customs processing may add additional delivery time.
Wholesale packaging: Vials may arrive without individual retail packaging or retail-style labels. Product identification and batch information should be verified using your order details and the applicable COA / batch documentation.
Lyophilized powder appearance may vary: Freeze-dried powder may shift, fragment, or separate during transportation. Changes in the physical appearance of the lyophilized puck are not, by themselves, considered a product defect.

Additional information

Overview

VIP (Vasoactive Intestinal Peptide) is a 28-amino-acid neuropeptide belonging to the secretin–glucagon peptide superfamily. It has the molecular formula C₁₄₇H₂₃₇N₄₃O₄₃S, a molecular weight of approximately 3326.8 g/mol, and CAS number 40077-57-4. First characterized from intestinal extracts, the peptide is widely distributed across the central and peripheral nervous systems and has been studied extensively in receptor-binding biochemistry.

VIP carries a C-terminal amide and signals through the class B G-protein-coupled receptors VPAC1 and VPAC2. Its full sequence is 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. The conserved N-terminal histidine and the central helical region are the structural determinants of receptor recognition in in-vitro studies.
