GHK-Cu 50MG

Product Overview

GHK-Cu 50MG is a copper complex of the tripeptide glycyl-L-histidyl-L-lysine, supplied as blue lyophilised powder in a 50mg catalogue presentation (SKU CU50). This page describes the stated research identity and batch-oriented catalogue specification; it does not provide an administration protocol.

GHK-Cu research examines copper binding, extracellular-matrix signalling, gene-expression changes and oxidative processes in cellular and tissue models.

Research Context

The following themes summarise published research on the named molecule or components. They are research contexts, not claims about the supplied ExtolX batch.

Areas of Research

• copper coordination and peptide chemistry
• extracellular-matrix and cell-migration models
• gene-expression and wound-model research
• oxidative-stress and metal-homeostasis assays

Evidence Quality and Limitations

Most evidence is cellular or preclinical, and outcomes depend on concentration, copper status and model. It does not establish consumer, cosmetic or therapeutic effects.

Storage and Handling

Before reconstitution: Keep the lyophilised vial sealed, dry and protected from light at −20°C or below, subject to the batch-specific supplier documentation. Published GHK-Cu reference-material data support frozen storage. Protect the material from light and contamination; colour alone does not confirm identity or stability.

After reconstitution: Stability depends on solvent, concentration, pH, container and method. If the validated method supports frozen storage, use single-use aliquots and avoid repeated freeze–thaw cycles. Avoid vigorous agitation, record the preparation and storage history, and investigate unexpected colour or particulate change. No numerical solution shelf life has been verified for this ExtolX batch.

Compatibility Limitations

Do not infer solubility or stability from another peptide, blend, amount or pharmaceutical formulation. Use small-scale method development and appropriate analytical controls before committing valuable material.

Laboratory Safety

Handle only in an appropriately equipped laboratory by trained personnel. Use a task-specific risk assessment, suitable personal protective equipment and applicable safety documentation. Avoid ingestion, inhalation, skin contact and environmental release, and dispose of waste in accordance with local requirements.
