GHK-Cu – High Purity Premium Peptide API

Product Overview GHK-Cu, officially named Copper Peptide GHK, is a natural-derived linear copper chelating peptide composed of glycine-histidine-lysine. Compared with AHK-Cu, it has milder biological activity and superior skin cell repairing performance. It can promote fibroblast proliferation, accelerate collagen and elastin synthesis, eliminate excess inflammatory factors, and accelerate superficial wound healing. It is applied in laboratory research including skin inflammatory repair, extracellular matrix regeneration, anti-oxidation, scar tissue remodeling and skin aging related pharmacological mechanism tests. It is extensively adopted in dermal cell signaling pathway exploration and cosmetic peptide efficacy evaluation. Adopting optimized solid-phase peptide synthesis and one-step copper chelation purification technology, the product boasts outstanding water solubility and stable chelation structure without dissociation after long-term storage.
