GHK-Cu: Research, Benefits & UK Availability

A naturally occurring copper-binding tripeptide researched for collagen synthesis, tissue remodelling, wound healing, and anti-aging applications.

Every Peptify GHK-Cu batch is independently HPLC-tested by Janoshik Analytical (Czech Republic) and ships with the batch-matched Certificate of Analysis.

What is GHK-Cu?

**Skin science.** GHK-Cu is the most-studied copper peptide in skin research — first identified in human plasma in 1973 and now backed by over 50 years of published literature. It is the natural copper-binding tripeptide present at birth, which research shows declines with age in measured human samples.

Studies have examined collagen types I, III, and V alongside elastin and proteoglycan synthesis in skin models. Anti-inflammatory cytokine signalling, hair follicle regeneration, wound closure, and antioxidant gene activity have been documented across decades of research — over 4,000 gene interactions reported, one of the broadest expression signatures in the catalogue.

50mg lyophilised vial sized for single-arm protocols and assay development. 99%+ HPLC purity, independently verified, batch-specific COA included. For in-vitro research use only.

How to Store GHK-Cu

Unreconstituted (Lyophilised Powder)

Store in a cool, dry place away from direct sunlight. For long-term storage, keep refrigerated at 2–8°C. Under these conditions, lyophilised peptides can remain stable for up to 24 months. For extended preservation beyond 24 months, store at -20°C in a freezer.

Reconstituted (Mixed with BAC Water)

Once reconstituted with bacteriostatic water, the peptide solution must be refrigerated at 2–8°C. Use within 4–6 weeks for optimal potency. Do not freeze reconstituted peptides as this may degrade the compound.

General Tips

Always keep vials upright to prevent leakage. Avoid repeated temperature fluctuations — do not leave vials out at room temperature for extended periods. Protect from light exposure by storing in the original packaging or a dark container. Label all vials with the reconstitution date.

Frequently Asked Questions

What does GHK-Cu do in research?

GHK-Cu stimulates collagen types I, III, and V, alongside elastin and proteoglycans. It is studied in the skin-regeneration, epithelial-barrier, and tissue-remodelling research literature.

What is the difference between 50mg and 100mg?

Both contain the same 99%+ purity GHK-Cu. The 100mg vial provides a larger quantity for extended research protocols.

Is GHK-Cu the same as copper peptide?

Yes. GHK-Cu is the scientific name for the copper tripeptide (Glycyl-L-Histidyl-L-Lysine Copper Complex) commonly referred to as copper peptide.
