KPV (Lys-Pro-Val) is the C-terminal tripeptide of alpha-melanocyte stimulating hormone (α-MSH), retaining the primary anti-inflammatory activity of the parent peptide. It acts as a melanocortin-1 receptor (MC1R) agonist and is also studied for direct intracellular NF-κB inhibition independent of receptor binding. The oral capsule format (4mg per capsule, 60 capsules) is particularly relevant for GI tract-targeted inflammatory research protocols.
KPV is studied in inflammatory bowel disease, intestinal permeability, skin inflammation, and systemic anti-inflammatory research. The oral capsule format is especially relevant for colonic delivery studies. Commonly paired with BPC-157 capsules for comprehensive GI integrity research panels.

Third order now. Consistent batch-to-batch results matter enormously in long-term research. Certificate of Analysis is detailed with mass spec data. Would not switch sources.
Verified against our reference standards. Purity >98.2% by HPLC. Packaging was appropriate for temperature-sensitive peptides. Will re-order.
