What is GHK-Cu?

GHK-Cu is a copper complex formed by the three-amino-acid peptide Gly-His-Lys and a copper ion. Researchers study this small complex because it combines a defined peptide ligand with biologically relevant copper-coordination chemistry.

Cell and tissue models have examined GHK-Cu in extracellular-matrix turnover, fibroblast signaling, gene-expression changes, and oxidative-stress pathways. The 100mg vial is a laboratory research format and should not be confused with a finished cosmetic or approved drug product.

How It Works

Binds and carries copper: The histidine-centered GHK structure coordinates Cu²⁺ for controlled copper-peptide research.

Influences matrix signaling: Laboratory studies have reported changes in collagen-related activity, matrix metalloproteinases, and extracellular-matrix remodeling.

Modulates cellular responses: Researchers continue to examine gene-expression, antioxidant, and inflammatory signaling associated with the complex.

Why Source from 321 Peptides?

Made under domestic control.

GHK-Cu is manufactured in GMP-certified laboratory facilities in California and Arizona, with no sourcing from overseas or Mexico. That keeps responsibility close to every production stage.

Copper-peptide identity verified.

Third-party HPLC evaluates the ≥99% purity target and mass spectrometry checks molecular identity. Both analyses appear on one batch-specific COA.

Lyophilized for stability.

The freeze-dried format protects the research material during storage and domestic transit. Fast U.S. fulfillment avoids a long international shipping chain.

Frequently Asked Questions

What is GHK-Cu peptide?

GHK-Cu is a complex of the tripeptide Gly-His-Lys and a copper ion. It is studied in laboratory models involving copper transport, cell signaling, and extracellular-matrix regulation.

What is the molecular weight of GHK-Cu?

The 1:1 prezatide copper complex associated with CAS 89030-95-5 has a molecular mass of approximately 402.92 g/mol. Other salts or stoichiometric forms can have different reported masses, so the batch COA should control.
