GHK-Cu 50mg

GHK-Cu 50mg Overview

GHK-Cu is a copper-binding tripeptide complex consisting of the amino acids glycine, histidine and lysine associated with a copper(II) ion. The GHK sequence occurs naturally and has been investigated for several decades in laboratory research.

A defining characteristic of GHK-Cu is its ability to bind copper. This distinguishes the copper complex from the uncomplexed GHK peptide and has led to research examining copper-dependent biological processes, cellular signalling and extracellular matrix activity.

GHK-Cu has been studied primarily in preclinical and laboratory models. Findings from these studies should not be interpreted as established effects in humans.

Interlink Peptides supplies GHK-Cu 50mg as a lyophilised preparation strictly for laboratory and scientific research applications.

Research Background

GHK-Cu has a comparatively long history within peptide research, with scientific investigation dating back several decades.

Published preclinical research has examined GHK-Cu in cellular systems involving fibroblast activity, extracellular matrix components and processes associated with collagen and glycosaminoglycan production.

Other laboratory research has investigated interactions involving matrix metalloproteinases, gene expression and copper-dependent cellular processes.

Copper is an essential cofactor in numerous biological systems, making the copper-binding properties of GHK particularly relevant when interpreting experimental results. Research involving GHK-Cu should therefore distinguish between effects associated with the peptide sequence and those associated with copper availability.

Despite its long research history, findings from laboratory and preclinical studies should not automatically be extrapolated to 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 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 reduce the possibility of condensation forming inside the vial.

Avoid unnecessary repeated freeze-thaw cycles. Preparation, solvent selection and experimental handling should be determined according to the receiving laboratory’s own validated protocols.

Quality & Testing

Certificate of Analysis documentation is available where applicable.

Analytical information concerning identity, purity and other specifications should be confirmed using the documentation associated with the relevant batch.

Frequently Asked Questions

What is GHK-Cu?

GHK-Cu is a copper-binding tripeptide consisting of glycine, histidine and lysine complexed with a copper ion. It has been investigated extensively in laboratory and preclinical research.

What is the difference between GHK and GHK-Cu?

GHK refers to the tripeptide Gly-His-Lys. GHK-Cu is the same peptide complexed with copper(II), giving it different chemical characteristics relevant to laboratory research.

Why does GHK-Cu have a blue appearance?

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

What form is GHK-Cu 50mg supplied in?

This product is supplied as a lyophilised preparation in a sealed vial containing 50mg of GHK-Cu.

Is a Certificate of Analysis available?

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

How should GHK-Cu be stored?

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