GHK-Cu Copper Tripeptide for Research
Technical Overview
GHK-Cu is a research-grade copper-binding peptide complex known for its role in tissue repair, wound healing and skin regeneration. Researchers study its effects on collagen production, inflammation and cellular repair, and it is widely used in research on skin aging and oxidative stress.
Research applications
- Collagen synthesis: how the peptide stimulates collagen production, skin elasticity and tissue repair.
- Tissue regeneration: its role in wound healing and recovery after injury.
- Inflammation modulation: its effects on inflammatory cytokines and immune responses.
- Oxidative stress defense: how it influences antioxidant activity and protection against environmental damage.
Mechanisms under study
Scientists explore how GHK-Cu activates regenerative pathways by increasing collagen and glycosaminoglycan synthesis, and its role in signaling pathways that regulate cell growth, angiogenesis and antioxidant defense. Researchers also assess its potential in hair follicle research and in tissue recovery after injury, giving it applications in both dermatology and regenerative research.

Storage Instructions
Handling and Storage Tips:
- On arrival, store the sealed vial at −20 °C, protected from light and moisture.
- For short-term storage (days to weeks), refrigeration at 2–8 °C is acceptable.
- Lyophilized peptides tolerate room temperature for short periods, such as during shipping.
- Let the vial reach room temperature before opening, to avoid condensation.
- Once reconstituted, keep refrigerated at 2–8 °C and avoid repeated freeze–thaw cycles.

Answers
Frequently Asked Questions
Is GHK-Cu third-party tested?
Yes. Each lot is tested by Bioviridian, an independent HPLC-MS laboratory, for identity (mass spectrometry), purity (RP-HPLC), content and endotoxin, and the Certificate of Analysis is published for that lot.
Can I see the Certificate of Analysis before buying?
Yes. Download it from the Documents section above, or search the lot number in our COA library.
What does 'Research Use Only' mean?
Products are supplied only for laboratory research. They are not drugs, foods, supplements or cosmetics and are not for human or veterinary use.
How is it shipped and stored?
Cold-packed with tracking, same day on orders by 2 PM ET. Store lyophilized vials at −20 °C on arrival.
