What is — GHK-Cu
GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine complexed with copper(II) ions). Peptworks supplies it as a lyophilized powder in 50 mg vials for laboratory research, at >=98% HPLC purity with an independent per-batch Certificate of Analysis. It is a research reagent for Research Use Only (RUO): it is not a medicine, supplement, cosmetic or medical device, and it is not for human or animal consumption. Available for B2B purchase as bulk unbranded vials (white-label), from EU-based stock.
In research models, GHK-Cu is studied as a copper(II) chelate: the tripeptide backbone binds a copper ion, and this complex is investigated in vitro and in preclinical systems for how it may shuttle copper to cells and interact with copper-dependent enzymatic and signalling pathways. Reported research directions include modulation of gene-expression patterns in cultured cells and interaction with extracellular-matrix remodelling pathways. All mechanistic descriptions here refer strictly to in-vitro and animal research models, not to any effect in humans.
Research
- Dermal fibroblast and skin-cell culture research
- Extracellular matrix and collagen/glycosaminoglycan synthesis models
- In-vitro wound-healing and tissue-remodelling assays
- Copper homeostasis and copper-transport studies
- Antioxidant and oxidative-stress model research
- Hair-follicle and dermal-papilla cell research
- Cosmetic-science formulation and stability research (non-clinical)
Advantages
- Studied in fibroblast cultures for effects on collagen and glycosaminoglycan synthesis in cell-model research
- Investigated in vitro for its role as a copper-delivery complex in cell-culture systems
- Examined in preclinical models for extracellular-matrix remodelling endpoints
- Used as a reference copper-peptide reagent in antioxidant and oxidative-stress assays
- Explored in animal and in-vitro models for tissue-remodelling and repair research endpoints
Safety
- Handling note: as a laboratory reagent, standard lab PPE (gloves, eye protection) is recommended; may cause irritation on contact
- Copper complexes can show concentration-dependent cytotoxicity in cell-culture models at elevated exposures, as reported in in-vitro literature
- Lyophilized peptide is hygroscopic; degradation or aggregation can occur if reconstitution and storage conditions are not controlled
- No human safety profile is claimed or implied; the material is Research Use Only and not for human or animal consumption
Ideal for
- Cosmetic-science R&D labs running non-clinical formulation and stability research
- Dermal fibroblast, ECM and collagen-synthesis research programmes
- Academic and contract research on copper homeostasis and oxidative stress
- B2B resellers and distributors supplying the research-reagent market in the EU
- White-label brands building a copper-peptide research catalogue under their own label
This product is a laboratory reagent supplied strictly for research. It is not a medicine, food or supplement and is not for human or veterinary use. It must be handled by qualified professionals under laboratory conditions.
Frequently asked questions
Where can I buy GHK-Cu in bulk in the EU?
Peptworks is a B2B wholesale supplier of GHK-Cu (50 mg lyophilized vial) with stock already inside the EU, so orders ship intra-community in 3-5 business days with no customs. You can order bulk unbranded vials (white-label). Orders start from a 4-vial pack per reference. Research Use Only; not sold to end users.
What is the wholesale GHK-Cu price per vial?
GHK-Cu 50mg has two public per-vial prices: €22.90 in a 4-vial pack and €14.00 from 10 vials of this reference (box price). There are no volume tiers. Shipping is free on orders from €500 (€24.90 below), inside the EU with no customs.
Do you offer GHK-Cu as white-label?
Yes, in the white-label sense: GHK-Cu comes in unbranded vials, with no brand on the vial, so you can resell it under your own label. Peptworks does not print or apply labels. Every batch is tested by an independent lab and ships from EU stock with no customs.
What is the minimum order for GHK-Cu?
The minimum is a 4-vial pack per reference; from 10 vials of a reference the lower box price applies. Vials ship in boxes of 10. There are no volume tiers, and orders from €500 ship free.
How is the GHK-Cu CoA verified?
Every box carries the Peptworks label with a unique QR code that links directly to that batch's Certificate of Analysis (HPLC identity/purity plus heavy metals), independently tested per batch. The CoA is verified through Peptworks, so your customers can confirm authenticity and >=98% HPLC purity for the exact batch they received.
How do I pay and how fast does GHK-Cu ship?
Payment is in crypto: USDC or USDT (Polygon or Base) or Bitcoin — paying in crypto is what keeps our prices this tight, with no card or bank fees. there is no card checkout on the site. Because stock is held inside the EU, orders ship intra-community in 3-5 business days with no customs clearance. The site is available in 10 languages (ES, EN, DE, FR, PT, IT, NL, PL, CS, EL).
