GHK-Cu is a naturally occurring copper tripeptide: the peptide glycyl-histidyl-lysine (GHK) bound to a copper ion. It is studied in skin and collagen research and supplied for research use only.
What it is made of
The name spells out the structure. GHK is a tripeptide of three amino acids: glycine, histidine, and lysine. Cu is copper, which the peptide binds tightly. Together they form the copper complex GHK-Cu.
A naturally occurring peptide
GHK occurs naturally in human plasma, and it is often noted that its levels decline with age. That natural origin is part of why the copper-bound form has drawn research interest.

Every Axis compound is third-party tested to 99.4%+ purity, with a certificate of analysis on every batch.
How it is studied
In the laboratory, GHK-Cu is studied in skin, collagen, and cosmetic research, which is why it is often grouped among carrier or copper peptides. As with any research peptide, it is a study tool, not a therapeutic, and it should come with a certificate of analysis.

A note on research use
The peptides supplied by Axis Peptide Labs are reference compounds for laboratory and research use only. They are intended for qualified researchers working in academic, institutional, and analytical settings. They are not drugs, foods, cosmetics, or medical products, and they are not intended for human or veterinary consumption. Documented identity and documented purity are what matter most when sourcing a compound, both of which are published on the Axis certificates of analysis page.
