Description

GHK-Cu Biovantage Labs Research Peptide

GHK-Cu (Glycine-Histidine-Lysine Copper Complex) is a naturally occurring copper-binding tripeptide studied for its role in collagen and glycosaminoglycan synthesis, wound repair signalling, and antioxidant gene expression in dermal and tissue research models. Biovantage Labs supplies GHK-Cu at 99+% purity, HPLC/MS verified. Domestically fulfilled from Canada. Not for human consumption. Biovantage Labs provides this compound at 99+% purity, confirmed by batch-specific HPLC and Mass Spectrometry analysis, as a lyophilized compound for use in controlled laboratory settings.

Molecular Profile and Chemical Specifications

Primary Research Mechanisms

GHK-Cu and AHK-Cu are structurally related copper tripeptides differing by a single N-terminal amino acid substitution (Gly vs. Ala). Research comparing their biological profiles examines whether this substitution produces meaningful differences in receptor interaction, tissue distribution, or biological activity, making the two compounds complementary tools for comparative copper tripeptide biology research.

Collagen and ECM Synthesis Stimulation

GHK-Cu is studied for its capacity to upregulate collagen I, III, and IV synthesis in dermal fibroblast models. Research also examines its stimulatory effects on glycosaminoglycan and proteoglycan production components of the extracellular matrix with direct relevance to tissue integrity research.

MMP Regulation and Tissue Remodelling

GHK-Cu demonstrates dual regulatory activity on matrix metalloproteinases (MMPs) in research models stimulating collagen-degrading MMPs while simultaneously upregulating their inhibitors (TIMPs). This balance is studied in the context of physiological tissue remodelling versus pathological degradation.

Antioxidant Gene Expression and Nrf2 Pathway

Gene expression studies have identified GHK-Cu-associated upregulation of antioxidant defence genes including superoxide dismutase and catalase. Research has linked this activity to Nrf2 pathway activation, a master transcriptional regulator of cellular antioxidant responses.

For wound healing and tissue remodelling research examining collagen synthesis signalling alongside repair pathway activation, BPC-157 is studied in adjacent contexts, its FAK-paxillin and VEGFR2-mediated mechanisms representing a distinct but convergent approach to extracellular matrix research.

Reconstitution Protocol

• Reconstitute using sterile bacteriostatic water or 0.9% sodium chloride solution
• Introduce diluent slowly along the interior vial wall. Do not inject directly onto the lyophilized cake
• Swirl gently until fully dissolved. Do not shake or vortex
• Allow the vial to equilibrate to room temperature before opening to prevent condensation

Storage and Stability

Store in a desiccated environment away from UV exposure. Avoid repeated freeze-thaw cycles, which degrade peptide chain integrity over time.

GHK-Cu Research FAQ

Q: Why does GHK-Cu appear blue in lyophilized form?

A: The characteristic blue colour results from the copper(II) coordination complex formed between the Gly-His-Lys peptide and a copper ion. The histidine imidazole and lysine amine groups coordinate the copper atom, producing the distinctive chromophore. This colour is an indicator of intact complex formation and is consistent across properly synthesised batches.

Q: Is GHK-Cu for human use?

A: No. GHK-Cu supplied by Biovantage Labs is strictly for laboratory research purposes. It is not approved for human consumption, veterinary use, or clinical application.

Q: What purity standard does Biovantage Labs apply?

A: Every batch is verified at 99+% purity using HPLC to confirm compound concentration and Mass Spectrometry to confirm molecular identity. Batch-specific COA documentation is available upon request.

Q: Where does Biovantage Labs ship from?

A: All Biovantage Labs products are fulfilled domestically from within Canada, eliminating customs clearance risk and reducing transit time compared to international suppliers.
