Description
GHK-Cu is a copper-associated tripeptide complex composed of the peptide sequence glycine-histidine-lysine coordinated with copper. It is supplied for controlled laboratory, analytical, and scientific research.
Because GHK-Cu is a coordination complex, preparations may differ in copper-to-peptide stoichiometry, hydration state, counter-ion form, and related molecular specifications. A single CAS number, molecular formula, or molecular weight should therefore not automatically be applied to every GHK-Cu preparation.
The exact complex identity, copper content, purity specification, and lot-specific analytical profile should be confirmed using the applicable Certificate of Analysis.
Research Applications
GHK-Cu may be examined in controlled non-clinical research involving:
- Metal-peptide complex characterization
- Copper coordination studies
- Peptide identity analysis
- Molecular interaction research
- Structure-function analysis
- Comparative analytical chemistry
- Chromatographic characterization
- Stability assessment
- Non-clinical biochemical and cellular models
Experimental observations should remain specific to the applicable research system and should not be interpreted as evidence of cosmetic, dermatological, regenerative, therapeutic, or clinical effectiveness.

Specifications & Documentation
Lot-specific documentation should be reviewed for:
- GHK-Cu identity
- Copper-to-peptide stoichiometry
- CAS reference, where applicable
- Molecular formula
- Molecular weight
- Counter-ion form
- Hydration state
- Copper content
- Purity specification
- Analytical testing
- Lot or batch information
- Certificate of Analysis
- Storage requirements
Authenticated product-specific documentation should take precedence over generalized GHK-Cu reference values.
Storage & Handling
Store according to the conditions specified on the product label and Certificate of Analysis. Protect the material from environmental conditions that could compromise peptide integrity or metal-complex stability.
Handling should follow established laboratory procedures appropriate for copper-containing peptide research materials.
