KLOW is a research peptide blend that combines GHK-Cu (Copper Tripeptide-1), BPC-157 (Body Protection Compound-157), TB-500 (Thymosin Beta-4 fragment), and KPV (Lys-Pro-Val) into a single synergistic formulation. This advanced combination builds on the “GLOW” blend by adding KPV to further target immune modulation and anti-inflammatory pathways. https://ionpeptide.com/product/klow/
