GHK-Cu 100mg

GHK-Cu 100mg Overview

GHK-Cu is a copper-binding tripeptide complex formed from the amino acids glycine, histidine and lysine together with a copper(II) ion. The naturally occurring GHK sequence has been studied for several decades, with laboratory research examining its copper-binding properties and interactions with a range of cellular processes.

The copper complex is chemically distinct from uncomplexed GHK. This distinction is important when interpreting research because copper acts as a cofactor in numerous biological processes and forms an important part of the experimental interest surrounding GHK-Cu.

This 100mg presentation provides a higher quantity of GHK-Cu than our 50mg vial for laboratory research requiring larger quantities of material.

Interlink Peptides supplies GHK-Cu 100mg as a lyophilised preparation strictly for laboratory and scientific research applications.

Research Background

GHK-Cu has a long history within peptide and copper-complex research.

Published laboratory studies have examined GHK-Cu in experimental systems involving fibroblasts, extracellular matrix components, collagen-related processes and cellular signalling.

Other areas of investigation include gene-expression responses and interactions involving matrix metalloproteinases and their regulatory pathways. Because GHK binds copper, researchers have also investigated the complex in relation to copper transport and copper-dependent biological processes.

The distinction between GHK and GHK-Cu is important in experimental design. Research findings involving the copper complex should not automatically be attributed solely to the peptide sequence, as copper availability may contribute to observed effects.

Although GHK-Cu has been studied for many years, much of the available evidence remains laboratory or preclinical in nature. Results from these experimental models should not automatically be interpreted as demonstrating effects in humans.

Interlink Peptides supplies GHK-Cu exclusively as a research material and makes no therapeutic, medical or cosmetic claims regarding this product.

Handling & Storage

Store GHK-Cu 100mg in its lyophilised form at approximately −20 °C, protected from light and moisture.

Once reconstituted with water, store refrigerated at approximately 2–8 °C.

Allow the sealed vial to reach an appropriate laboratory working temperature before opening to minimise condensation inside the vial.

Avoid unnecessary repeated freeze-thaw cycles. Solvent selection, preparation and experimental handling should be determined by the receiving laboratory according to its own validated protocols.

Quality & Testing

Certificate of Analysis documentation is available where applicable.

Information concerning identity, purity and other analytical specifications should be confirmed against the documentation associated with the relevant batch.

A lower-quantity GHK-Cu 50mg presentation is also available for research requiring a smaller quantity of material.

Frequently Asked Questions

What is GHK-Cu?

GHK-Cu is a complex formed from the tripeptide Gly-His-Lys and a copper(II) ion. It has been investigated in laboratory research for several decades.

What is the difference between GHK and GHK-Cu?

GHK is the three-amino-acid peptide Gly-His-Lys. GHK-Cu is the copper-bound form of that peptide, giving the complex different chemical characteristics relevant to laboratory investigation.

What is the difference between the 50mg and 100mg products?

Both products contain GHK-Cu. The difference is the quantity of lyophilised material supplied: this presentation contains 100mg, while the alternative presentation contains 50mg.

Why is GHK-Cu blue?

The characteristic blue appearance is associated with the copper complex and is expected for GHK-Cu preparations.

Is a Certificate of Analysis available?

Certificate of Analysis documentation is available where applicable. Analytical specifications should be checked against the documentation associated with the relevant batch.

How should GHK-Cu 100mg be stored?

Store the lyophilised product at −20 °C, protected from light and moisture. Once reconstituted with water, store refrigerated at 2–8 °C.
