GHK-Cu
Copper peptide researched for skin regeneration and collagen support.
Mechanism of Action
A naturally occurring tripeptide (Glycyl-L-Histidyl-L-Lysine) that forms a complex with copper(II) ions. Research indicates it modulates ~4,000 human genes, downregulating those associated with inflammation and tissue breakdown while upregulating genes tied to collagen synthesis, antioxidant defense, and stem cell activation.
Research Areas
Common Research Protocols
Used at 1–3 mg/mL in serums in dermatological studies for fine-line and texture endpoints.
Investigational subcutaneous administration explored for systemic regenerative endpoints.
Protocols summarized for educational reference from published research. Not dosing guidance.

Resetting skin genome back to health
Documented gene expression changes restoring older skin patterns toward youthful profiles.
Important Considerations
- •Topical formulations have decades of cosmetic safety data; injectable use is less studied.
- •Copper sensitivity is rare but possible.
- •Compounded injectable GHK-Cu is not FDA-approved.
