Product Information

Note: Final specifications, test methods and acceptance criteria are subject to the confirmed batch COA and customer requirements.

Product Overview

GHK-Cu is a copper coordination complex formed from the tripeptide Gly-His-Lys and copper ions. It is widely studied as a functional peptide material for cosmetic formulation development, skin biology research and peptide-metal complex studies.

ASCENT supplies GHK-Cu as a peptide raw material with batch-specific analytical documentation and customized specifications for qualified business and research customers.

The material is generally supplied as a blue powder. Its color may be characteristic of the copper complex, but appearance should not replace identity, purity, copper-content or peptide-content testing.

Research Basis

Copper-Peptide Coordination

The Gly-His-Lys sequence can coordinate copper ions to form the GHK-Cu complex. Its properties may be influenced by the copper-to-peptide ratio, pH, counter-ions, water content and formulation conditions. Professional evaluation should therefore consider both peptide purity and complex-related quality parameters.

Skin and Formulation Research

GHK-Cu has been studied in areas including:

• Skin biology and cell-based research
• Extracellular matrix-related pathways
• Fibroblast-response studies
• Oxidative-stress-response research
• Topical delivery and skin-penetration evaluation
• Cosmetic formulation stability and compatibility
• 
  

Core Applications

1. Cosmetic Formulation Development

Suitable for professional formulation development and compatibility evaluation in:

• Facial serum formulations
• Cream and lotion systems
• Eye-area formulation research
• Scalp and hair-care formulations
• Post-procedure cosmetic formulation research
• Professional-use cosmetic prototypes

Finished-formulation performance depends on concentration, pH, temperature, preservatives, chelating agents and other ingredients. Compatibility and stability testing should be completed by the formulator.

2. Skin Biology Research

• Fibroblast-related studies
• Cell-culture experiments
• Extracellular matrix research
• Oxidative-stress-response studies
• Peptide signaling and biochemical research

3. Peptide-Copper Complex Studies

• Copper-binding behavior
• Peptide-metal coordination
• Complexation ratio and pH-dependent stability
• Copper release and interaction studies
• Analytical characterization of metal-peptide complexes

4. Analytical Method Development

• HPLC method development
• Mass-spectrometry identification
• Copper-content and peptide-content determination
• Stability-indicating method development
• Raw-material specification establishment
•
