About GHK-Cu as a research material
What it is
A naturally occurring tripeptide sequence with high affinity for copper(II) ions. The complex is supplied as a lyophilized powder with the characteristic deep blue colour of bound copper, and requires reconstitution before laboratory use.
How it is studied
Published GHK-Cu research covers collagen and glycosaminoglycan synthesis in fibroblast cultures, dermal-matrix remodeling, wound-healing models and gene-expression profiling. Atlas supplies the material only; we do not provide protocols, dosing guidance, or human-use instructions.
Handling and storage
Store the lyophilized vial at -20°C, protected from light. Reconstitute immediately before laboratory use and keep the reconstituted solution refrigerated; avoid strong reducing agents and chelators that displace the bound copper.
Verification
Each lot is analysed by an independent laboratory using HPLC for purity and mass spectrometry for identity against a ≥99% purity target. The COA for your lot is published as a downloadable PDF on the product page.
GHK-Cu — common questions
- What is GHK-Cu?
- GHK-Cu is a copper-binding tripeptide made of glycine, histidine and lysine complexed with a copper(II) ion. It is one of the most widely studied peptides in dermal and tissue-remodeling research.
- Why is the powder blue?
- The blue colour comes from the bound copper(II) ion. A pale or colourless powder can indicate the copper is not properly complexed — check the lot COA for identity confirmation.
- What sizes are available?
- 50mg and 100mg lyophilized vials. Pricing is listed above and volume discounts apply automatically in the cart.
- Is a certificate of analysis included?
- Yes. The batch-specific COA for the lot you receive is downloadable from the product page and our COA library.
- Is this for human use?
- No. All Atlas Peptides materials are sold strictly for in-vitro and pre-clinical laboratory research. They are not for human or veterinary consumption.
