The Science of Klow

GHK-Cu is a copper-binding peptide the body makes on its own, and its levels fall sharply with age. It is studied for signaling skin cells to produce collagen and elastin, the proteins that give skin its firmness and bounce, and for supporting the skin's own repair process.

BPC-157 and TB-500 are the recovery pairing found in Wolverine 1. BPC-157 is studied for supporting the blood supply that healing tissue depends on, and TB-500 for the cell migration and collagen organization that rebuild it. KPV, a fragment of the hormone alpha-MSH, is studied for calming inflammatory signaling.
