GHK-Cu

GHK-Cu is a naturally occurring copper-binding tripeptide with the sequence Gly-His-Lys (Copper Tripeptide-1). It is one of the most extensively researched copper peptides, valued in the laboratory for the way it coordinates a copper ion — a feature central to the pathways it is studied within.

In research settings, GHK-Cu is examined for collagen and elastin synthesis promotion, MMP modulation, angiogenesis pathways, and dermal tissue remodeling. Investigators use in-vitro dermal and connective-tissue models to explore how a copper-binding tripeptide influences these interconnected skin and matrix mechanisms. GHK-Cu also appears as a component of the Glow and KLOW research blends. All material supplied here is intended strictly for in-vitro laboratory research.

GHK-Cu is offered in 50mg and 100mg vials so research groups can match quantity to study scale — the 100mg vial being more economical per milligram for larger dermal-research protocols. Both are lyophilized and third-party lab tested at ≥98% purity by HPLC, with a Certificate of Analysis available on request by email. Because copper peptides are light-sensitive, storage away from direct light is particularly important: keep vials cool, dry, and shielded from light, refrigerate for longer-term storage, and avoid repeated temperature swings.
