Copper coordination. Matrix remodeling. One tripeptide complex.
GHK-Cu is studied as a copper(II)-coordinating tripeptide complex. The literature below describes experimental fibroblast and extracellular-matrix models, not clinical guidance.
-
Copper coordination
The Gly-His-Lys tripeptide forms a defined complex with copper(II) ions.
-
Collagen synthesis
Fibroblast studies have examined GHK-Cu in relation to collagen production.
-
Glycosaminoglycans
Cell-culture research has measured changes in extracellular glycosaminoglycan synthesis.
-
Matrix remodeling
Published fibroblast work evaluates GHK-Cu alongside matrix metalloproteinases and their inhibitors.

Common questions
Research context, batch testing, storage and verification for GHK-Cu.
What is GHK-Cu?
GHK-Cu is a copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine. It is also indexed as copper tripeptide-1 and prezatide copper. Prime Peptides supplies it strictly as lyophilized material for in-vitro laboratory research.
What is the molecular weight of GHK-Cu?
PubChem lists prezatide copper, CAS 89030-95-5, with a molecular weight of approximately 402.92 g/mol and the formula C14H23CuN6O4+. This is the copper complex; uncomplexed GHK has a lower molecular weight.
How does GHK differ from GHK-Cu?
GHK is the three-amino-acid peptide Gly-His-Lys. GHK-Cu is the coordinated copper(II) complex. Because copper coordination changes the chemical identity and molecular weight, this product record uses the GHK-Cu complex values.
What research areas are associated with GHK-Cu?
Peer-reviewed studies investigate GHK-Cu in fibroblast models of collagen synthesis, glycosaminoglycan production and extracellular-matrix remodeling. These research contexts do not establish a medical, therapeutic or veterinary use for this product.
How does Prime Peptides test GHK-Cu?
Every batch goes through three layers of quality control. Our manufacturer runs its own QC and has its production independently tested by Janoshik Analytical. Then Vanguard or Janoshik tests every batch we stock again, for identity, HPLC purity, net content and endotoxins before we approve it for sale.
Every approved batch has its lab report on the Test Results page.
What purity standard does Prime Peptides use?
We target 99%+ purity by HPLC. The actual purity of each batch is measured independently and published in its lab report, so you can check the result yourself.
How should GHK-Cu research material be stored?
Store the sealed lyophilized vial at -20°C, protected from light, and follow the product label and batch documentation. After reconstitution, use controlled refrigerated laboratory storage at 2-8°C within the defined research window and avoid repeated freeze-thaw cycles.
Where can I find published research on GHK-Cu?
The Selected literature section links to PubMed records covering copper coordination, collagen synthesis, glycosaminoglycan synthesis and extracellular-matrix remodeling in experimental systems.
