TB-500 | 10mg | 3ml
TB‑500 is a synthetic peptide based on the active region of thymosin beta‑4, designed for controlled experimental use in studies focused on actin‑binding behaviour, cellular migration, and cytoskeletal organisation. It serves as a research analogue for examining how thymosin beta‑4–related sequences influence structural and motility‑associated cellular processes. In biochemical and cell‑based research systems, peptides derived from thymosin beta‑4 are evaluated for their ability to interact with G‑actin, affecting actin polymerisation and broader cytoskeletal remodelling. The responses observed in experimental models vary according to peptide concentration, exposure time, cell type, and overall study design.

How we ship it
Every pre-mixed vial leaves the UK cold and arrives in a plain box. Refrigerate on arrival at 2–8 °C.
Chilled
Vials travel with frozen gel packs inside a sealed foil pouch, which holds temperature for roughly seven days in transit.
Insulated
The pouch sits inside a wool-lined envelope, so the cold chain survives a normal courier journey.
Discreet
Plain outer box with no branding and nothing on the label that names the contents.
Same-day dispatch
Order before 3pm GMT, Monday to Friday.
Free over £100
Tracked UK delivery, next working day.
2–8 °C on arrival
Refrigerate as soon as the parcel lands.

TB-500: research FAQs
- What is TB-500?
- TB-500 is a synthetic peptide based on the active region of thymosin beta-4, a naturally occurring actin-binding protein. It belongs to the family of thymosin beta-4-related sequences and serves as a research analogue for studying that class of peptides. It is supplied strictly for in-vitro laboratory research use only, not for human or veterinary use.
- What is TB-500 studied for in research?
- In biochemical and cell-based research systems, thymosin beta-4-derived peptides have been investigated in preclinical work for their ability to interact with G-actin, influencing actin polymerisation and broader cytoskeletal reorganisation. In-vitro and preclinical models have also examined their relationship to cell migration and the structural organisation of the cytoskeleton. These are laboratory observations only; the responses recorded vary with peptide concentration, exposure time, cell type and study design.
- Is TB-500 legal to buy in the UK?
- TB-500 is legal to buy and possess in the UK for laboratory research purposes. It is not a licensed medicine and cannot be sold for human consumption. Every unit ships labelled for in-vitro research use only.
- What purity is your TB-500, and is it lab-tested?
- Our TB-500 is verified at 99%+ purity by HPLC analysis. The figure printed on each batch's Certificate of Analysis is the actual lab-recorded value for that batch, not a marketing claim. It is synthesised and dispatched from our own UK facility.
- Does TB-500 come with a Certificate of Analysis?
- Yes, a batch-specific Certificate of Analysis (COA) ships with every order. You can also view sample COAs in our COA library before purchasing, so the documentation can be reviewed in advance.
- How is TB-500 supplied, stored and handled for research?
- TB-500 is supplied as a pre-mixed solution in a sealed vial — no reconstitution step is required. Its batch Certificate of Analysis records the appearance as a clear liquid. Refrigerate at 2°C–8°C, keep the vial sealed and away from light, and do not freeze it: freeze-thaw cycling can damage peptides already in solution. Handling should follow standard aseptic laboratory practice within an appropriate research setting.
