What is GHK-Cu?

GHK-Cu is a bioactive copper complex peptide consisting of three amino acids (glycine, histidine, and lysine) bound to a Cu²⁺ ion. GHK-Cu was first identified in human plasma by Dr. Loren Pickart in the 1970s, where it was found in higher concentrations in younger blood. Its molecular formula is C₁₄H₂₃CuN₅O₅, with a molecular weight of approximately 404 g/mol. The structure consists of a linear tripeptide backbone with a coordinated copper atom essential for the molecule's biological activity.

Analysis and identity

Every batch is tested independently by an external laboratory. The certificate of analysis for this product is available on this page and states the method used, the purity determined and the date of analysis.

Available variants

GHK-Cu is available in 50mg and 100mg. The current price for each is shown with the product options on this page.

Storage and Handling

GHK-Cu powder should be stored at 2-8°C (refrigeration) in a dry environment, protected from light and moisture. Unopened original packaging can remain stable for up to 24 months under these conditions. After opening, the product should be stored in sealed containers under the same conditions and preferably under an inert gas atmosphere (nitrogen).

For reconstitution, sterile water or 0.9% sodium chloride is recommended. The peptide is highly soluble in water and mild acidic solutions. Reconstituted solutions should be stored at 2-8°C and used within 2 weeks to minimize degradation. It is advisable not to repeatedly freeze and thaw suspended solutions.
