THE SCIENCE, SIMPLIFIED
How GHK-Cu Works
Multi-Pathway Regeneration
GHK-Cu is a naturally occurring tripeptide that binds with copper to create a powerful regenerative complex. Released from damaged collagen as an injury signal, it orchestrates healing by modulating thousands of genes involved in tissue repair, inflammation control, and cellular protection.
Primary
Gene Expression
Epigenetic Modulation
- Upregulates 59% of affected genes
- Activates 47 DNA repair genes
- Suppresses inflammatory pathways
Strongest
Collagen Pathway
Collagen & ECM Synthesis
- Stimulates type I & III collagen
- Increases elastin production
- Enhances ECM remodeling
Supportive
Copper Delivery
Copper Ion Transport
- Delivers copper to cells
- Activates SOD antioxidant
- Supports wound healing enzymes

COMPOUND DETAILS
Compound Information
What Is GHK-Cu?
GHK-Cu (Glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper-binding tripeptide first identified in human plasma in 1973. It is released from tissues during injury and plays a key role in tissue remodeling, wound healing, and regenerative signaling. Research has shown it modulates thousands of human genes involved in repair, antioxidant defense, and anti-inflammatory processes.
