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. Every batch is quality-controlled and batch-specific COA can be supplied on request. Unopened product should be kept sealed at 2-8 degree C away from light and moisture, with -20 degree C recommended for long-term storage. We accept both trial and bulk orders, and OEM and private-label service is available. This peptide is for laboratory research use only. The copper tripeptide coordination chemistry is central to its reported effects on collagen synthesis, wound repair and antioxidant defense, and investigators study it in skin and tissue models. Its natural occurrence supports translational relevance. The lyophilized powder is supplied with purity data. The lyophilized format provides excellent stability and simplifies reconstitution for reproducible dosing.
