AHK-CU

AHK-Cu (Copper Tripeptide-3) is a synthetic copper-binding tripeptide composed of alanine, histidine, and lysine complexed with a copper ion (Cu²⁺). It has been studied in research settings for its role in skin and hair follicle–related cellular signaling pathways, including mechanisms involving dermal papilla cells, growth factor signaling, and extracellular matrix regulation.
