GHK-Cu (Copper Tripeptide-1) is a naturally occurring copper-binding tripeptide with the sequence glycyl-histidyl-lysine, widely studied in skin, connective-tissue and anti-aging research. It is supplied as a high-purity blue lyophilized powder (>=99% HPLC) in sealed vials for laboratory and cosmetic raw-material studies. GHK-Cu is investigated for collagen synthesis, wound healing, antioxidant activity and skin-regeneration applications, and is frequently applied in cell-culture and topical-formulation research. The stable freeze-dried presentation ensures convenient reconstitution and reproducible dosing. Every batch undergoes strict quality control, and a Certificate of Analysis (COA) is available for specific batches upon request to support reproducible laboratory work. For storage, keep the unopened reagent sealed at 2-8 degree C and protected from light and moisture; for long-term storage, store at -20 degree C and avoid repeated freeze-thaw cycles. We support both small trial orders and large-volume bulk orders. OEM and private-label packaging services are available for research projects, and secure neutral packing is used for all shipments with worldwide delivery to the USA, Europe, Canada, Australia, the UK and many other regions.
