Product Overview
GHK-Cu is a naturally occurring copper complex of the tripeptide Glycyl-L-Histidyl-L-Lysine.
The "Blue" Marker of Authenticity:
Unlike almost all other research peptides, which are white powders, GHK-Cu is distinctive for its vibrant blue colour. This hue is not a dye; it is the physical evidence of the copper ion (Cu2+) being complexed within the peptide structure.
Originally isolated from human plasma in the 1970s, GHK-Cu is chemically distinct because it acts as a feedback signal for tissue remodeling. Research indicates that the peptide facilitates the uptake of copper into cells—a trace element vital for the enzymatic function of lysyl oxidase (required for collagen cross-linking). Consequently, GHK-Cu is the primary reagent used to investigate skin regeneration, collagen synthesis (Types I & III), and the down-regulation of inflammatory cytokines.
Quality Assurance
This compound has undergone rigorous third-party analysis.
- HPLC Verified: Independent analysis confirms peptide purity exceeds 99%.
- Copper Chelation: Verified to ensure the peptide is fully complexed with copper (giving it the blue colour) rather than a simple mix of peptide and copper salts.
- TFA Removal: Processed to remove inflammatory salts.
Research Mechanism
In laboratory settings, GHK-Cu is utilised to investigate:
- ECM Remodeling: The balance between breaking down old, damaged collagen (via metalloproteinases) and synthesising new, healthy connective tissue.
- Fibroblast Activation: Researching the acceleration of wound healing and the "youthful" gene expression patterns in aged fibroblasts.
- Stem Cell Potential: Studies examining the peptide's ability to restore the proliferative potential of epidermal stem cells (p63 marker).
- Anti-Inflammation: Reducing oxidative stress and suppressing pro-inflammatory molecules like TNF-alpha and IL-6.
Safety and Handling
WARNING: This product is exclusively for laboratory research and in vitro use.
- Research Only: Not intended for human consumption, cosmetic application, or therapeutic use.
- Handling: Wear appropriate personal protective equipment (PPE).
Storage: Store lyophilised vials in a cool, dry place. For long-term preservation, freezing at -20°C is recommended.
