Third-Party Tested
GHK-Cu is a copper-containing synthetic peptide supplied as lyophilized research-grade material. The product is provided for controlled laboratory research, analytical characterization, and comparative peptide studies. Each batch is independently tested according to applicable quality-control procedures, with batch documentation available where applicable. Research Use Only (RUO). Not intended for human or veterinary use.
Research Compound Overview
GHK-Cu is a copper-containing peptide complex supplied for laboratory research. Its molecular composition and copper-binding characteristics make it suitable for analytical characterization, comparative peptide studies, and controlled laboratory research. Product identity, purity, available batch documentation, and physical specifications should be evaluated using the applicable product and batch documentation.
Primary Research Mechanisms
GHK-Cu may be included in controlled laboratory studies involving peptide characterization, copper-peptide interactions, analytical testing, and comparative research involving related peptide compounds.
Available Sizes — 50mg and 100mg
50mg (Single Vial): Suitable for standard research protocols, dose-response studies, and initial gene expression profiling work.
100mg (Single Vial): Larger format for extended protocols, quantitative gene expression studies requiring higher compound volumes, or research programs studying multiple tissue models simultaneously.
Both sizes are from the same production batch — only the vial quantity differs. Select your size from the dropdown on the product page.
Reconstitution Note
Reconstitution and preparation should follow the applicable product documentation and the requirements of the relevant laboratory protocol.

Frequently Ask Questions
What is the difference between GHK-Cu and AHK-Cu?
GHK-Cu (Glycyl-Histidyl-Lysine + copper) has glycine at the N-terminal position. AHK-Cu (Alanyl-Histidyl-Lysine + copper) has alanine instead of glycine at position 1. This single amino acid substitution produces structurally distinct copper complexes with partially different biological research profiles. GHK-Cu has over five decades of published research and the 4,000-gene genomic analysis. AHK-Cu is a newer research compound studied for structure-activity comparison - how the Ala vs Gly substitution affects copper binding, cellular uptake, and downstream signaling.
Why does GHK-Cu have a blue-green colour?
GHK-Cu may exhibit a blue to blue-green appearance due to the presence of the copper complex. Appearance can vary depending on formulation and physical state. Product appearance should be evaluated together with the applicable batch documentation and quality-control information.
What is the reconstitution solvent for GHK-Cu?
Refer to the applicable product documentation and laboratory protocol for the appropriate preparation medium. Compatibility and solubility should be evaluated for the specific research application.
Is GHK-Cu approved for human use?
No. Our research-grade GHK-Cu is supplied strictly for laboratory and controlled scientific research purposes only (RUO). It is not intended for human or veterinary use.
