GHK-CU
From A$74.99
GHK-CU is a copper(II)-binding tripeptide (Gly-His-Lys) that forms a stable 1:1 complex with Cu²⁺ and is studied in extracellular matrix gene-expression and wound-signalling assay models.
The copper complex changes the optical and electrochemical properties of the peptide relative to the metal-free form, which makes analytical characterisation methods (UV-Vis, circular dichroism, ICP-MS for copper quantification) relevant workflow steps before cell-based experiments. Comparative studies between GHK and GHK-Cu allow researchers to attribute transcriptional or matrix effects specifically to copper coordination versus the bare tripeptide scaffold.

In research literature, GHK-CU is generally treated as a copper(II)-binding tripeptide (Gly-His-Lys) that forms a stable 1:1 complex with Cu²⁺ and is studied in extracellular matrix gene-expression and wound-signalling assay models. GHK binds Cu²⁺ with extraordinary affinity (Kd ≈ 10⁻¹⁵ M) via coordination through the glycine α-amino group, histidine imidazole Nδ, and the lysine α-amino group — a square-planar complex that remains intact under physiological conditions. The copper-loaded form (GHK-Cu) has been studied for upregulation of collagen I, collagen III, fibronectin, and the proteoglycan decorin in fibroblast assay models, with mechanistic proposals centring on TGF-β pathway modulation and activation of metalloenzymes. Gene-expression profiling studies report broad transcriptional changes across matrix-remodelling, antioxidant defence, and neurotrophin-related gene sets, making it a tool for wide-scope transcriptomic research in addition to targeted pathway assays.
The copper complex changes the optical and electrochemical properties of the peptide relative to the metal-free form, which makes analytical characterisation methods (UV-Vis, circular dichroism, ICP-MS for copper quantification) relevant workflow steps before cell-based experiments. Comparative studies between GHK and GHK-Cu allow researchers to attribute transcriptional or matrix effects specifically to copper coordination versus the bare tripeptide scaffold. For laboratory teams, the practical emphasis is usually on sequence identity, receptor or pathway relevance where documented, and whether GHK-CU behaves consistently across stability, purity, and analytical verification workflows. Variant labels on this page support clearer internal referencing when multiple labelled variants are under review.
Potential research applications for GHK-CU should be framed strictly in analytical and laboratory terms. Typical reasons a team might review this product page include:
Handling decisions should always follow the vial label, internal SOPs, and any product-specific documentation. A conservative laboratory baseline for GHK-CU is:
A product-specific COA is linked on this page, with purity noted as 99.490%. The COA section is useful for confirming how the product is labelled in the catalogue, whether purity information has been published, and whether the laboratory record for the material is complete before bench use.
When teams compare GHK-CU with CJC (NO DAC) + IPA, Ipamorelin, and TB-500, COA access also helps keep comparator decisions grounded in documented material identity rather than assumption. That is especially important for research pages that combine pricing, variant selection, and analytical records on a single URL.

It brings together 2 labelled variants: 50mg and 100mg, current pricing context, stock visibility, COA access, and internal links to related catalogue pages so a laboratory buyer can review the material from a single reference URL.
GHK-CU is generally discussed as a copper(II)-binding tripeptide (Gly-His-Lys) that forms a stable 1:1 complex with Cu²⁺ and is studied in extracellular matrix gene-expression and wound-signalling assay models. The most relevant background is sequence behaviour, pathway or receptor context where documented, and analytical consistency under controlled laboratory conditions.
Use the label, COA, and internal SOPs as the primary guide. In general, store the material under controlled laboratory conditions, minimise avoidable environmental exposure, and keep variant tracking records current.
Yes. This listing includes access to a product-specific COA, which should be reviewed before use so purity, identity, and documentation checks are aligned with the project record.
No. The page should be interpreted strictly in a research and laboratory context. It does not provide dosage guidance, treatment claims, or human or animal use instructions.
