What GHK-Cu is
GHK is a tripeptide (glycyl-L-histidyl-L-lysine) that forms a complex with copper(II). The copper complex is the form most often used in published research, and gives the material its characteristic blue colour in solution.
It is listed as a laboratory research material and is not offered for cosmetic or human application. See the compliance page for official TGA guidance.
What the published research investigates
The literature examines GHK-Cu in extracellular-matrix and dermal fibroblast models, copper transport, and gene-expression studies.

Storage & handling in the lab
Aussie Peptides does not publish product- or lot-specific preparation, storage or stability data. Base preparation, storage and disposal on the supplier safety data sheet (SDS) and your institution's standard operating procedures.
Where a vial label shows a lot number and a batch report has been published for that lot, it can be looked up on the verify page and recorded alongside your experimental data.
Legal status in Australia
Materials on this site are supplied strictly for in-vitro laboratory research. They are not offered for human or veterinary use. A research-use label does not by itself determine regulatory status; see the compliance page for official TGA guidance.
Purchasers must be 18 or over and are responsible for handling, storing and disposing of research materials in line with their institution's requirements and applicable Australian law.
Nothing on this page is medical advice, a dosing protocol, or a claim of therapeutic benefit. It summarises what the published research literature investigates.
Common questions
The colour comes from the copper(II) ion coordinated by the tripeptide. A blue tint in solution is expected for the copper complex.
Where a batch report has been published for a given lot, it can be looked up on the verify page.
No. We supply it strictly for in-vitro laboratory research. It is not supplied for application to skin or any human use.
