Overview
A naturally occurring copper-binding tripeptide characterized for its role in extracellular-matrix remodeling and fibroblast signaling in vitro.
GHK-Cu delivers copper ions to cells and has been studied for its influence on fibroblast activity and extracellular-matrix remodeling — modulating the synthesis of collagen, elastin and glycosaminoglycans, and shifting gene-expression profiles in cultured cells.

Common questions
Research FAQ: eligibility, shipping, payment and returns
What is GHK-Cu studied for?
Research focuses on extracellular-matrix remodeling — collagen, elastin and glycosaminoglycan synthesis — and copper delivery to cultured cells.
Why is it blue in solution?
The color comes from the bound copper (Cu²⁺) ion, which is integral to the peptide's studied activity. Protect from light and store cool.
How is it supplied?
Each listing identifies the supplied format (lyophilized powder in a sealed vial) and storage conditions. Batch-specific documentation is shown when published. We do not provide reconstitution, dosing or administration guidance.
How is purity verified?
The product page shows the current batch documentation status. When a reviewed certificate is published, open the laboratory PDF for its reported methods and results. Only use analytical methods and identity results explicitly recorded for that batch. For other records, ask the research desk.
Who can order?
These are research-use-only materials sold to qualified researchers and institutions. They are not for human or veterinary use, consumption, or any diagnostic, therapeutic, cosmetic or food application.
