Download COA (PDF)KLOW is a precision-formulated four-component research blend developed by 21 Peptide, containing KPV (Lys-Pro-Val, an α-MSH-derived tripeptide), GHK-Cu (copper tripeptide-1), TB-500 (Thymosin Beta-4, 43 amino acid chain), and BPC-157 (Body Protection Compound pentadecapeptide). Each component is individually studied in experimental biology, and together they represent a multi-mechanism research system targeting several complementary pathways across cellular signaling, extracellular matrix regulation, melanocortin receptor biology, and connective tissue research.
Current research investigates the individual components of KLOW across a range of biological systems, including skin fibroblast models, melanocortin receptor pathway studies, anti-inflammatory signaling research, connective tissue biology investigations, and cytoskeletal dynamics research. Studies conducted in controlled laboratory settings have examined KPV for its melanocortin receptor interactions, GHK-Cu for its collagen synthesis signaling, BPC-157 for its multi-tissue signaling activity, and Thymosin Beta-4 for its actin-binding properties.
21 Peptide™ supplies KLOW exclusively for scientific research purposes. This compound is not approved for human or animal consumption and is not intended for diagnostic, therapeutic, or clinical use.
