99.79% Purity Avg. mass 108.37 mg Each vial contains a precision-blended combination of BPC-157, TB-500, KPV, and GHK-Cu. KLOW is a proprietary four-peptide research blend engineered to target overlapping yet mechanistically distinct pathways across immune modulation, inflammatory signaling, tissue regeneration, and extracellular matrix remodeling. BPC-157 activates growth factor cascades and cytoprotective pathways involved in musculoskeletal and gastrointestinal tissue repair. TB-500 (Thymosin Beta-4) drives cell migration, angiogenesis, and wound resolution while suppressing fibrotic scarring. KPV — a C-terminal tripeptide fragment of alpha-MSH — exerts potent anti-inflammatory effects through NF-κB pathway inhibition and has demonstrated immunomodulatory activity in mucosal tissue models. GHK-Cu is a copper-binding tripeptide that stimulates collagen synthesis, activates tissue remodeling genes, and functions as a signaling molecule in wound repair and antioxidant defence. By combining these four compounds in a single formulation, KLOW enables researchers to investigate multi-pathway crosstalk and synergistic interactions that single-peptide protocols cannot capture.
