AHK-Cu (copper tripeptide-3) is a synthetic copper-binding tripeptide formed from alanine, histidine and lysine, related to GHK-Cu and studied for effects on hair-follicle biology, collagen remodeling and skin-cell signaling. Its distinct sequence supports comparative studies among copper peptides in cosmetic and dermatological research. The product is a blue-white lyophilized powder at >=99% HPLC purity in a sealed vial. Batch certificates, custom packaging and international logistics are available for laboratory buyers.
