GHK-Cu Copper Tripeptide
GHK-Cu is the copper(II) complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine. ZENTRA supplies it as high-purity lyophilised research material in 50mg and 100mg formats for controlled laboratory and analytical applications.
The peptide component contains three amino acids with the sequence Gly-His-Lys (GHK). Copper coordination is central to the identity of GHK-Cu; the supplied material should not be described as ordinary GHK or as a generic copper salt.

Independent Batch Testing
Every current ZENTRA GHK -Cu batch is independently tested and records an HPLC purity result above 99%. The batch number on the product label can be checked against the corresponding third-party report in our Batch Verification and COA Centre. Researchers should consult the individual report for the exact analytical methods, result and testing date for their supplied batch.
GHK -Cu Research Context
Published laboratory work has investigated GHK-Cu in fibroblast behaviour, extracellular-matrix regulation and wound-model signalling. A study using irradiated human fibroblasts examined cell growth and growth-factor expression. Other experimental work investigated sulphated glycosaminoglycan synthesis and matrix-metalloproteinase expression in fibroblast and wound models.
These studies identify mechanisms and research questions; they do not establish a therapeutic effect, safety profile or approved injectable use in humans. The chemical form, copper coordination, concentration and experimental model all materially affect interpretation.
Storage and Handling
For long-term storage, keep unopened lyophilised material at approximately -20°C. For short-term laboratory storage, maintain at 2-8°C. Protect the vial from light, moisture and repeated temperature changes. Use appropriate laboratory handling procedures and consult your institutional protocol before preparing research solutions.
GHK-Cu Research FAQs
What is GHK-Cu?
GHK-Cu is a copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine. It is studied as a copper-binding signalling complex rather than as a conventional longer-chain peptide.
What is the GHK-Cu sequence?
The peptide component is the three-amino-acid sequence Gly-His-Lys, written GHK.
Why is GHK -Cu blue?
The blue appearance is associated with copper coordination in the complex. Appearance alone is not an identity or purity test, so the matching analytical report should still be checked.
Which sizes are available?
This product is available as 50mg and 100mg of lyophilised research material.
How is purity verified?
Every current batch is independently HPLC tested above 99% purity. Use the label batch number to locate the corresponding third-party report online.
Is this product intended for human or veterinary use?
No. ZENTRA GHK -Cu is supplied strictly for laboratory research and analytical purposes.
