What Is TB-500?
TB-500 is a synthetic peptide corresponding to an active region of Thymosin Beta-4, a naturally occurring peptide present in many cell types. The synthetic fragment is produced for research and supplied as a lyophilised (freeze-dried) powder. It is highly water soluble, which makes it straightforward to prepare in the laboratory.
Everything on this page describes the handling and properties of a research compound in a laboratory context only. It is not guidance for human or animal use. Products supplied by North Peptides UK are for research use only and are not for human or animal consumption.
Why Is TB-500 Studied?
TB-500 is a frequent subject of preclinical research. Scientific interest centres on tissue-repair research models and on cell-migration and actin-regulation research, where Thymosin Beta-4 and its fragments are investigated. The available work is laboratory and animal-model research.
Because this is an active research area rather than settled science, TB-500 is supplied purely as a reference research compound. North Peptides UK makes no claims about effects in humans, and nothing here is guidance for human or animal use.
How TB-500 Is Supplied
TB-500 is stocked as a 10mg lyophilised vial, listed with supplier-stated 99%+ purity and stored frozen until dispatch, with supplier documentation available on request where held. It is UK stocked and dispatched within 24–48 hours of confirmed payment on business days. It is also one of the four compounds in the KLOW Stack research blend.
Handling and Reconstitution
TB-500 is reconstituted with bacteriostatic water. It is highly soluble; the solution may look slightly cloudy at first but clears with gentle swirling. Add the solvent down the inside wall of the vial, swirl rather than shake, and label the vial with the preparation date. See our reconstitution guide for the full procedure.
Storage and Stability
In lyophilised form, TB-500 is stable and kept frozen for longer-term storage, away from light. Once reconstituted, refrigerate the solution at 2–8°C, keep it out of direct light, and avoid repeated freeze–thaw cycles. With bacteriostatic water, a reconstituted solution typically stays stable for up to 28 days when refrigerated.
Sourcing TB-500 in the UK
North Peptides UK stocks TB-500 domestically, so there are no import delays for UK-based researchers. Every batch is listed with supplier-stated 99%+ purity with supplier documentation available on request where held.
