GHK-Cu, also known as Copper Tripeptide-1, is a naturally occurring copper-binding tripeptide with the sequence glycyl-histidyl-lysine, widely studied in skin and connective-tissue research. It is supplied as a high-purity lyophilized powder, >=99% by HPLC, in sealed vials for laboratory and cosmetic raw-material studies. GHK-Cu is investigated for its roles in collagen synthesis, wound healing, antioxidant activity and skin-regeneration applications, and is frequently applied in cell-culture and topical-formulation research. The lyophilized format provides high stability and easy reconstitution for reproducible experimental dosing. Quality control is performed on each batch with batch COA available on request. Keep the product sealed at 2-8 degree C, protected from light and moisture; for long-term storage -20 degree C is recommended and repeated thawing should be avoided. We accept both sample and bulk orders, offer OEM and private label service, and arrange discreet neutral packing for worldwide shipping. Intended for laboratory research only, not for human or veterinary application.
