Tripeptide-copper complex studied for roles in tissue remodelling, dermal research, and antioxidant pathways.
GHK-Cu is a naturally occurring tripeptide-copper complex (Glycyl-L-Histidyl-L-Lysine bound to a copper(II) ion) found in human plasma at levels that decline with age. It is among the most extensively studied copper peptides in dermatological and regenerative research literature, with published work covering skin remodelling, hair-follicle research, and wound-healing models. Quantum Labs supplies GHK-Cu as a lyophilised powder for Australian research applications.
GHK-Cu sits unusually across the Australian regulatory landscape — listed cosmetic formulations are available alongside research-grade supply. Our material is HPLC-verified to ≥99% purity and supplied for research use, ships from Australian stock, and is accompanied by batch identifiers traceable to the certificate of analysis.
Research on GHK-Cu spans dermal collagen synthesis models, hair-follicle stem-cell signalling, and broader regenerative pathways including modulation of TGF-β and integrin expression. Topical and injected delivery formats have both been used in pre-clinical study designs.
Research Mechanism
Studied for interactions with copper-dependent enzymes and collagen synthesis markers in research models.
HPLC verified against a ≥99% purity specification. Independently tested by accredited third-party laboratories.
Why the copper matters
The tripeptide GHK without copper has measurable but limited biological activity. The copper-bound form GHK-Cu shows substantially expanded activity profiles in research models — copper coordination appears to be essential for many of the regenerative effects studied in the literature. Quantum Labs supplies the pre-formed GHK-Cu complex rather than GHK alone, ensuring researchers work with the active form characterised in published studies.
GHK-Cu — frequently asked questions
What is GHK-Cu?
GHK-Cu is a tripeptide-copper complex — Glycyl-L-Histidyl-L-Lysine bound to copper(II). It occurs naturally in human plasma and is studied for its role in skin remodelling, hair-follicle research, and wound-healing pathways.
Is GHK-Cu legal in Australia?
GHK-Cu has dual regulatory pathways in Australia — listed cosmetic formulations are available alongside research-grade supply for laboratory use. Quantum Labs supplies research-grade GHK-Cu without therapeutic representation, for laboratory research applications.
What does GHK-Cu do in research?
Published research on GHK-Cu spans dermal collagen synthesis models, hair-follicle stem-cell signalling, modulation of regenerative pathways (TGF-β, integrin expression), and wound-healing models. It is one of the most studied copper-binding peptides in regenerative research.
What's the difference between GHK and GHK-Cu?
GHK is the tripeptide Glycyl-L-Histidyl-L-Lysine. GHK-Cu is the same tripeptide complexed with a copper(II) ion. The copper-bound form shows substantially expanded biological activity in research literature, and is the form characterised in most published studies.
Can GHK-Cu be used topically?
Topical GHK-Cu formulations are used in both cosmetic products and research applications. Research studies have used topical, subcutaneous, and intradermal delivery formats. The compound penetrates skin in suitable carrier formulations.
What is the typical GHK-Cu research dosage?
Topical research formulations have used concentrations from 0.05% to 5% depending on the model. Injected research doses vary substantially by study design. Researchers should reference primary literature for protocol-specific guidance.
Where can I buy GHK-Cu in Australia?
Quantum Labs supplies research-grade GHK-Cu from Australian stock, HPLC-verified to ≥99% purity. Domestic shipping is typically 2-5 business days.
