    About GHK-Cu as a research compound

    GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) first isolated from human plasma in the 1970s. Endogenous GHK-Cu concentrations decline sharply with age, which is why the synthetic form has become one of the most extensively studied peptides in the dermatology and regenerative-research literature.

    Published research covers wound healing models, collagen and elastin synthesis assays, anti-oxidant and anti-inflammatory cell studies, hair follicle research, and gene-expression work. GHK-Cu has been shown in transcriptomic studies to modulate the expression of more than 4,000 human genes, making it a uniquely well-characterised reference compound for tissue-remodelling research.

    All GHK-Cu vials ship as lyophilised powder with the characteristic blue tint from the copper-binding complex. Reconstitution with bacteriostatic water yields a stable solution that should be refrigerated at 2 to 8 Celsius.

    Why research labs buy GHK-CU from Peptx

    Factory-direct sourcing

    Peptx sources directly from manufacturers cross-referenced against independent ISO 17025 lab testing. No middlemen and no compounding-pharmacy markups; just the factory price plus a small fixed margin.

    Manufacturer HPLC data

    Manufacturer HPLC and Mass Spectrometry data sits behind Peptx material at typically 99%+ purity (HPLC). Documentation is not shipped with orders. Independent ISO 17025 lab retesting is encouraged; a 14-day refund window applies to any independently verified result below the product's stated guaranteed minimum purity.

    GHK-CU buying FAQ

    Why is GHK-Cu blue in colour?▼
    The blue tint is the visible signature of the copper-tripeptide chelation complex. A faint blue colouration in the lyophilised vial or reconstituted solution is normal and confirms that the copper ion is properly bound.
    How should GHK-Cu be stored?▼
    Lyophilised GHK-Cu is stable at room temperature for short periods, but transfer to a freezer for long-term storage. Once reconstituted with bacteriostatic water, refrigerate at 2 to 8 Celsius, protect from light, and use within 6 to 8 weeks.
    What is the difference between GHK and GHK-Cu?▼
    GHK is the bare tripeptide; GHK-Cu is the same tripeptide pre-chelated with a copper ion. Almost all published research uses the copper-bound form, which is biologically active and stable. Peptx stocks the copper-bound GHK-Cu form by default.
    Do you ship GHK-Cu worldwide?▼
    Yes, Peptx ships GHK-Cu worldwide with full tracking. Standard transit is 3 to 5 working days within the UK and 5 to 10 working days to most international addresses.
    Is GHK-Cu legal to purchase for research?▼
    GHK-Cu is not a controlled substance in any major Western jurisdiction and can legally be purchased for in-vitro research. It is sold for cosmetic-research and tissue-remodelling laboratory work only. All Peptx products are sold strictly for in-vitro laboratory research and are NOT for human or animal consumption.
