AHK-Cu
Mechanism.
AHK-Cu is a copper-binding tripeptide (Ala-His-Lys-Cu) structurally related to GHK-Cu, the well-studied copper peptide. It has been investigated for its ability to stimulate hair follicle growth, promote collagen synthesis, and support wound healing. Research is primarily in vitro and in cosmetic science contexts.
Think of AHK-Cu as a delivery truck that brings copper — a key building material — directly to your skin and hair follicle construction sites, helping workers (cells) build stronger structures and grow faster.
