GHK-Cu

SUPPLIED QUANTITY & FORMAT

Vial quantity, not a dosing schedule.

This listing supplies 50 mg per vial, with 10 vials per pack. The labeled quantity describes the material supplied; it is not a recommended dose or a prepared-solution concentration. No human or animal dosing instructions are provided.

Freeze-dried powder

The supplier describes the material as lyophilized, or freeze-dried, powder. Lyophilization removes water from a frozen preparation. The dry vial is not a ready-to-use liquid, and a labeled mass does not specify a final concentration. Follow the batch-specific technical documentation for laboratory handling and storage. Freeze-drying alone does not establish purity, sterility, or shelf life; review the supplier’s batch documentation.

COMPOUND OVERVIEW

What is GHK-Cu?

A copper complex of the tripeptide glycyl-L-histidyl-L-lysine. The peptide and its copper-bound form are related but distinct chemical entities.

THE SCIENTIFIC QUESTIONS

What is being researched?

Cell-culture research has examined collagen synthesis in fibroblasts. Research questions also concern how copper coordination changes the behavior of a short peptide in extracellular-matrix models.

Research possibilities

This chemistry provides a framework for studying interactions between trace-metal binding, cellular signaling, and matrix production. It supports mechanistic investigation rather than a guarantee of visible or functional changes.

Supplier and batch documentation

Peptide Express resells third-party materials in wholesale packs, fulfilled by third-party suppliers. Ask for the current certificate of analysis, composition, identity testing, and handling documentation for the actual batch. Supplier-reported testing has not been independently verified here.
