What is — TB-500
TB-500 is a synthetic acetate form of a fragment corresponding to Thymosin Beta-4 (Tβ4), supplied by Peptworks as a lyophilized 5 mg powder in a single-use vial for laboratory research only. Thymosin Beta-4 is a naturally occurring 43-amino-acid actin-binding peptide widely used as a reference compound in cell-biology and tissue-repair research models. Peptworks stocks it inside the EU for B2B wholesale and white-label resale, with >=98% HPLC purity and an independent per-batch Certificate of Analysis. It is a research reagent only, not for human or animal consumption.
In research models, Thymosin Beta-4 is studied primarily as a G-actin-sequestering peptide: it binds monomeric actin and modulates the polymerization dynamics of the actin cytoskeleton, a process central to cell migration. Preclinical and in-vitro literature also explores its association with endothelial cell migration, angiogenesis assays, and modulation of inflammatory and extracellular-matrix pathways. All mechanistic description here refers strictly to in-vitro and animal research contexts and does not imply any effect in humans.
Research
- Actin cytoskeleton dynamics and cell-motility assays
- In-vitro wound-closure and cell-migration models
- Angiogenesis and endothelial cell research
- Preclinical tissue-repair and regeneration models
- Inflammation and extracellular-matrix signalling studies
- Cardiac and dermal repair models in laboratory animals
Advantages
- Studied in preclinical models for its role in cell migration and tissue-repair pathways
- Used as a reference actin-binding peptide in cytoskeleton research
- Investigated in angiogenesis and endothelial migration assays
- Applied in in-vitro wound-closure models to study re-epithelialization dynamics
- Explored in animal models of dermal, muscular and cardiac repair
Safety
- As a research reagent, safety in humans has not been established and it is not for human use
- Preclinical literature is limited; toxicological profiles vary by model and are not standardized
- Reconstituted peptide is sensitive to temperature, repeated freeze-thaw and contamination, which can affect experimental reproducibility
- Handle with standard laboratory PPE; effects reported in animal or in-vitro studies do not translate to human outcomes
Ideal for
- Research laboratories studying cytoskeletal and cell-migration biology
- Resellers and distributors needing bulk research-peptide inventory from EU stock
- White-label brands building a research-peptide catalogue under their own label
- Academic and preclinical groups requiring documented per-batch CoA purity
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 TB-500 in bulk in the EU?
Peptworks supplies TB-500 (5 mg lyophilized vials) wholesale from stock already inside the EU, so orders ship intra-community in 3-5 business days with no customs. You buy either as bulk unbranded vials (white-label). Orders start from a 4-vial pack per reference. Research use only; not for human or animal consumption.
What is the wholesale price per vial for TB-500?
TB-500 5mg has two public per-vial prices: €39.90 in a 4-vial pack and €25.00 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. 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.
Do you offer TB-500 as white-label?
Yes, in the white-label sense: TB-500 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 TB-500?
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 TB-500 Certificate of Analysis verified?
Every batch ships with an independent Certificate of Analysis covering HPLC purity (>=98%) and heavy metals. Each box carries a unique QR code that links directly to that batch's CoA, verified through Peptworks, so you and your customers can confirm authenticity per batch.
Is TB-500 from Peptworks sold for human use?
No. Peptworks is a B2B wholesale and white-label supplier of research reagents. TB-500 is supplied strictly for laboratory research use only (RUO); it is not a medicine, supplement, cosmetic or medical device, and is not for human or animal consumption. Peptworks does not sell to end consumers.
