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 or as white-label vials boxed under the reseller's own brand, 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 or white-label vials boxed under your own brand. Minimum order is 10 units (1 box) per reference. Research Use Only; not sold to end users.
What is the wholesale GHK-Cu price per vial?
Pricing is public and per vial, with combined-volume discounts applied to the whole order: 100 units at EUR 18.00/vial (base), 300 units at EUR 14.76/vial (-18%), 500 units at EUR 13.50/vial (-25%), and 1000 units at EUR 12.24/vial (-32%). It is a single tier based on your combined total units, not stacked discounts.
Can I get white-label GHK-Cu with my own brand?
Yes. Peptworks offers two formats: bulk unbranded vials, or white-label vials labelled with your own brand and boxed. A one-time label setup fee of EUR 180 applies to orders under 100 units, and is free from 100 units. Each box carries a Peptworks label plus a unique QR that links to the batch CoA.
What is the minimum order for GHK-Cu?
The minimum order is 10 units (1 box) per reference. Vials always ship in boxes of 10, and the box is the unit that carries the Peptworks label and the batch QR code.
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 by USDC bank transfer / invoice; 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).
