GHK-Cu Peptide Research Summary

GHK-Cu (copper peptide GHK) is a naturally occurring tripeptide first isolated from human plasma by Dr. Loren Pickart in 1973. The peptide consists of three amino acids (glycine-histidine-lysine) with a high affinity for copper(II) ions. Published studies have documented interactions with extracellular matrix components and growth factor signaling in dermatological and wound healing research models.

About this GHK-Cu reference material

GHK-Cu is supplied by Maple Research Labs as a lyophilised powder in a sealed vial under catalogue reference GHKCU-50MG. Every vial is drawn from a single production batch and is released only against a batch-specific certificate of analysis. The batch documented for this listing was tested by Testides Analytical, an independent third-party laboratory, and the report reference is shown in the specification above.

Analytical specification for this GHK-Cu batch

Identity and purity were determined by high-performance liquid chromatography with ultraviolet detection (HPLC-UV) and reported at 99.56%. The material is registered under CAS 49557-75-7, molecular formula C14H23CuN6O4. HPLC-UV separates the target compound from related substances and process impurities and quantifies each as a percentage of total peak area, which is why the result is stated to two decimal places rather than as a rounded claim. Public registry data for CAS 49557-75-7 can be checked independently via PubChem.

What a batch-specific COA means

A batch-specific certificate describes the exact material in the vial being shipped, not a representative sample from an earlier production run. Where a supplier publishes a single document covering an entire product line, that certificate cannot describe the unit received. Maple Research Labs does not publish a GHK-Cu listing without a matching batch document, and the certificate for this batch is downloadable from this page.

Handling and storage

Supplied as a lyophilised powder. Store sealed vials away from light and moisture; refrigeration extends the shelf stability of the dry powder. Allow a chilled vial to reach ambient temperature before opening, to limit condensation on the stopper. Handle in a controlled laboratory environment using appropriate personal protective equipment, and record the batch reference against your own experimental documentation.

Availability and shipping

Orders ship from the United States. GHK-Cu is listed as a single vial, so a laboratory can verify the certificate and the material against its own analytical methods before committing to a larger order.

Third-party testing and traceability for GHK-Cu

Testing for GHK-Cu is commissioned from Testides Analytical, a laboratory independent of both Maple Research Labs and the manufacturer. Independent testing matters because an in-house result is produced by the party with an interest in the outcome, and a third-party result is not. Each certificate states the analytical method used, the date of analysis and the batch identifier, so a result can be traced to a specific production run rather than to a product name in general.

Laboratories sourcing GHK-Cu for method development or comparative work generally need three things on file: a purity figure produced by a stated method, a batch identifier that matches the vial in hand, and a supplier willing to publish both before purchase rather than after. Those are the terms this listing is published on, and the certificate is available without an account or an enquiry.
