Copper and GHK-Cu in physiology papers

Research-use notice: This article is laboratory and educational information only. It is not medical or legal advice, and it does not include how-to-use instructions.

Copper is an essential trace element used by enzymes in collagen cross-linking (lysyl oxidase), mitochondrial electron transport, superoxide dismutase, and selected neurotransmitter pathways. GHK (glycyl-L-histidyl-L-lysine) is a tripeptide that binds Cu²⁺ to form GHK-Cu. The complex is a research ligand, not a synonym for dietary copper.

What papers measure

Primary literature reports gene-expression changes, extracellular-matrix components, and wound-model histology under defined conditions. Secondary sources sometimes inflate that into “reset signals” or hair-growth promises. This page stays with the narrower claim: GHK-Cu is widely cited in matrix and signaling papers, and results depend on model, dose in the assay, and formulation.

Plasma GHK concentrations are reported to decline with age in some studies. That observation is not a treatment recommendation.

Catalog versus physiology textbook

BlueNex Labs supplies GHK-Cu as a research-use-only lyophilized solid with Canada-only fulfilment. Confirm the lot on the COA library section. Do not interpret shop availability as evidence that copper-peptide physiology has been translated into an authorized product.

How to use this note with the catalog

Copper-peptide biochemistry in papers is not a consumer supplement claim. The laboratory fill, when stocked, is listed at GHK-Cu 50mg with Canada-only shipping.

Orders ship inside Canada only after Interac e-Transfer checkout. Sold-out SKUs remain listed and cannot be added to the cart. Match each vial to its own Certificate of Analysis when a lot is published. Research-use only. Not for human or veterinary use.
