GHK-Cu (CAS 49557-75-7, molecular formula C14H22CuN6O4) — also written GHK Cu or GHKCu, and known chemically as copper tripeptide-1 — is a naturally occurring copper peptide studied for its role in cellular signalling and tissue remodelling research. PhaseOne has GHK-Cu copper peptide for sale online to Australian researchers as a high-purity lyophilised powder, independently HPLC verified at ≥99% purity per batch.
As one of the more established copper peptides in Australian peptide research, GHK-Cu is manufactured to research-grade standards and independently third-party tested for identity and consistency, with every order shipped Australia-wide in 50mg and 100mg vials. (!) Full Certificate of Analysis available for every batch view here.
GHK-Cu is a copper-binding tripeptide (glycyl-L-histidyl-L-lysine bound to copper) naturally present in human plasma at low concentrations, and is one of the most studied copper peptides among Australian peptide researchers for its interaction with extracellular matrix signalling.
Copper peptide is the everyday name for a peptide that binds a copper ion. GHK-Cu is the best known example — the tripeptide GHK complexed with copper. When a listing refers to a copper peptide without further detail, GHK-Cu is usually the compound meant.
Yes. Copper tripeptide-1 is the formal chemical name for GHK-Cu. The same compound also appears as GHK Cu, GHKCu, GHK copper peptide and copper peptide GHK — all describe the glycyl-L-histidyl-L-lysine copper complex.
Yes — PhaseOne has GHK-Cu copper peptide for sale online in 50mg and 100mg vials, shipped Australia-wide. Worth checking the format before ordering: most online listings for copper peptide are cosmetic serums and creams rather than research material, so confirm whether a listing is a finished topical product or a raw lyophilised powder with a batch Certificate of Analysis.
They are different product categories. A copper peptide serum or cream is a finished cosmetic product, formulated with GHK-Cu at low concentration alongside other ingredients and sold for topical use on skin or hair. PhaseOne supplies GHK-Cu as a raw lyophilised research powder in 50mg and 100mg vials, intended strictly for laboratory research and not as a cosmetic preparation. The two are not interchangeable.
They are entirely different things. A copper supplement is a dietary mineral product supplying elemental copper. GHK-Cu is a specific tripeptide that carries a copper ion as part of its structure, supplied as a research compound rather than a nutritional product.
PhaseOne ships GHK-Cu copper peptide Australia-wide for research use, dispatched locally with tracking, in 50mg and 100mg vials. Every vial carries a batch-specific Certificate of Analysis verifying ≥99% HPLC purity.
PhaseOne prices GHK-Cu at A$55.99 for a 50mg vial and A$95.99 for 100mg, with the batch Certificate of Analysis included at no extra cost.
Chemist Warehouse and other Australian chemists stock cosmetic products that list copper peptides among their ingredients, but not research-grade GHK-Cu in vial form. PhaseOne supplies GHK-Cu as a lyophilised research powder in 50mg and 100mg vials, which is a different product category.
Laboratory interest in GHK-Cu commonly centres on its copper-chelating properties, antioxidant pathway research, and collagen-related signalling studies. (!) Read more in our GHK-Cu research hub.
Unreconstituted GHK-Cu should be stored refrigerated, away from direct light. It is commonly reconstituted with bacteriostatic water immediately prior to research use. (!) Read our reconstitution guide.
Every PhaseOne batch is independently verified by third-party HPLC testing, with a Certificate of Analysis available on request - a standard we apply to all research peptides sold across Australia.
GHK-Cu is available in 50mg and 100mg vials, both shipped Australia-wide with full batch documentation.
Yes - GHK-Cu is one of the three peptides in our GLOW Blend, and one of the four in our KLOW Blend, both combining it with BPC-157 and TB-500 for researchers studying skin and tissue-related signalling together. (!) View our GLOW Blend or KLOW Blend.
