Klow

Klow 80 mg is a four-component research blend supplied as a single lyophilized preparation. Each vial contains 80 mg of total peptide, made up of 10 mg BPC-157, 10 mg TB-500, 50 mg GHK-Cu, and 10 mg KPV. The 80 mg figure is the combined mass of all four peptides in the vial, not the amount of any single component.

Adding KPV to the three-peptide Glow base is its defining feature, bringing a melanocortin-derived anti-inflammatory component into the combination. In vitro research examines the interplay of angiogenic and cytoprotective signaling (BPC-157), actin and extracellular-matrix regulation (TB-500), copper-dependent collagen and matrix pathways (GHK-Cu), and NF-kappaB-linked anti-inflammatory signaling (KPV).

Klow is the more anti-inflammatory-weighted counterpart to Glow, which omits KPV and centers on collagen and skin-matrix pathways. The two blends are otherwise identically proportioned, so Klow is Glow's 70 mg base plus 10 mg of KPV. Supplied as a lyophilized 10-vial kit at 80 mg per vial (800 mg total peptide) for in vitro research use only.
