What is GHK-Cu studied for in research?

GHK-Cu is investigated in vitro for its copper-binding properties and interaction with skin, hair-follicle and extracellular-matrix signalling pathways under controlled laboratory conditions.

What purity is your GHK-Cu?

Every 100mg vial is tested to 99%+ purity by HPLC. A batch-specific Certificate of Analysis is available on request.

Why is the powder blue?

GHK-Cu is a copper-peptide complex — the characteristic deep-blue colour comes from the coordinated copper(II) ion bound to the GHK tripeptide.

How should GHK-Cu be reconstituted and stored?

Reconstitute with bacteriostatic water in a sterile laboratory environment — use our peptide calculator for target concentrations. Refrigerate the reconstituted solution at 2–8°C and avoid repeated freeze-thaw cycles.
