GHK
glycyl-histidyl-lysine · tripeptide-1 · copper-free GHK
The copper-free glycyl-histidyl-lysine tripeptide studied as the ligand behind GHK-Cu.
About GHK
GHK is the naturally occurring tripeptide glycyl-L-histidyl-L-lysine — the copper-free ligand that, when bound to copper, forms GHK-Cu. It is studied in matrix-biology research both on its own and as the copper-carrier precursor. TagPep references GHK as a research-use-only reference material.
Mechanism studied in research
A high-affinity copper(II) ligand; studied for gene-expression modulation in dermal-research models and as the coordinating peptide in copper-delivery research.
Areas of research investigation
- Copper-coordination chemistry
- Matrix-biology research
- Comparative GHK vs GHK-Cu studies
- Peptide-ligand assays
Laboratory handling
Lyophilized; reconstituted with sterile or bacteriostatic water for research and stored refrigerated and light-protected, powder frozen.

GHK research FAQ
Why study GHK without copper?
GHK on its own is studied as a copper ligand and matrix-signaling peptide; comparing it to GHK-Cu isolates the contribution of the bound copper ion. See our GHK-Cu vs GHK page.
Is GHK available separately?
GHK is referenced for research context; TagPep currently stocks the copper-complexed GHK-Cu form. Contact us about copper-free GHK availability.
