GHK-Cu 100mg
Skin & Hair Research
Overview
GHK-Cu is a copper-binding peptide complex studied within research environments for its interaction with cellular and biochemical pathways.
Classification: Copper tripeptide-1 (Gly-His-Lys) complexed with divalent copper (Cu²⁺) — a naturally occurring plasma tripeptide first identified in human serum in 1973.
Research background
Within laboratory settings, GHK-Cu is studied for its interaction with cellular and biochemical pathways. Research applications focus on peptide stability, receptor binding activity, and signalling pathway modelling under controlled experimental conditions.
This summary describes published preclinical and, where applicable, clinical research. It is not a medical claim and does not describe or endorse any human use of the compound as sold by Peptides UK 4U.
Mechanism of action (under investigation)
Published research investigates GHK-Cu as a copper-delivery ligand and modulator of dermal fibroblast gene expression, extracellular-matrix protein transcription and antioxidant-response pathways. In vitro studies also explore effects on collagen and glycosaminoglycan synthesis by cultured fibroblasts.
Laboratory handling
This product is typically reconstituted using bacteriostatic water or a suitable sterile solvent within a controlled laboratory setting. All handling should be carried out by qualified professionals using appropriate sterile techniques and safety procedures.
Storage & stability
- Store in a cool, dry environment before reconstitution.
- For extended stability, storage at -20°C is recommended.
- Avoid repeated freeze-thaw cycles after reconstitution.
For reconstitution volumes and target working concentrations use our peptide calculator. We do not publish dosing protocols for human use.

Frequently asked questions
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 ≥98% 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.
