    About this Product

    KLOW is a synergistic, four-peptide formula—BPC-157, GHK-Cu, TB-500, and KPV—designed to accelerate injury healing, reduce chronic inflammation, and promote tissue regeneration at the cellular level. Known as a "quad-peptide" formula, it is used for tissue repair, gut health, enhanced athletic recovery, and improved skin firmness.
