Molecular Structure:   Product Description: GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a synthetic tripeptide-metal coordination compound composed of a defined three-amino-acid sequence (Gly-His-Lys) bound to a copper ion. The compound is produced through controlled synthesis and metal-complexation processes and is provided exclusively for in vitro research in qualified laboratory settings. GHK-Cu is structurally characterized and utilized in controlled experimental environments for analytical and experimental evaluation of peptide–metal coordination chemistry and associated physicochemical properties. This product is supplied as a pre-formulated aqueous research solution, designed to provide consistency and stability for controlled research applications. This material is not formulated for cosmetic, clinical, diagnostic, or therapeutic use. Research Applications:

• Analytical evaluation of peptide–metal complex structure and composition
• Examination of stability and binding characteristics of copper-associated peptide systems
• Investigation of peptide behavior in biochemical and in vitro assay environments
• Characterization of interactions between peptide complexes and defined experimental systems

Storage and Handling:

• For optimal stability, store sealed product in a cool, dark, and dry environment. Refrigeration at 2–8 °C is recommended after first puncture or once the seal has been compromised
• Do not freeze
• Protect from light
• Maintain sterile handling practices during research use

Product Specifications:

• Bottle Volume: 30 mL
• Total Content: 50 mg per bottle
• Dispenses per Container: ~200
• Per Dispense: ~250 mcg
• Appearance: Blue to blue-green aqueous solution
• Analytical Approach to Finished Formulations: Purity is a metric used for isolated raw materials, such as lyophilized peptide powders. Finished formulations—such as capsules, liquids, and topicals—contain multiple components, including excipients and stabilizers. In these systems, a single purity value does not accurately represent the overall composition. Instead, identity and assay (content) are reported on the COA to confirm the presence of the correct compound and to verify that the labeled amount per unit is accurate. This approach reflects standard analytical practice and provides more meaningful information for research applications.
