TB-500 UK — buying guide
What to check before you buy TB-500 in the UK: the thymosin beta-4 fragment studied alongside BPC-157 in tissue-repair research.
What is TB-500?
TB-500 is a synthetic peptide corresponding to the biologically active region of thymosin beta-4, a naturally occurring protein involved in actin regulation and cell migration. It carries CAS number 77591-33-4 and a molecular weight of 4963.44. Rather than reproducing the full parent protein, TB-500 represents the short fragment identified in research as central to thymosin beta-4's actin-binding activity — a common source of confusion when buying.
Across tissue-repair research TB-500 is studied for its reported role in cell-migration and wound-model systems, and it is frequently paired with BPC-157 in comparative designs. Sova supplies it strictly as a characterised reference material — not for human or veterinary use, and with no claim of any effect in people.
Before you buy
How to verify TB-500 before you buy
The main thing to check when buying TB-500 is that you are getting the characterised fragment, not mislabelled full-length thymosin beta-4 — a mass-spec result against 4963.44 Da tied to the batch is how you confirm it.
Every Sova TB-500 vial ships with a batch-linked Certificate of Analysis. Before you buy, confirm the CoA references the batch on the vial, that identity is confirmed by ESI mass spectrometry against the expected 4963.44 Da, and that purity is measured by reverse-phase HPLC. Enter the batch at /verify to pull the certificate.

TB-500 — frequently asked
Is TB-500 legal to buy in the UK?
TB-500 is supplied in the UK as a research chemical for laboratory research use only. It is not an authorised medicine and is not sold for human or veterinary use, and can be purchased by researchers aged 18 or over on that basis.
How is Sova's TB-500 verified?
Each batch is analysed by reverse-phase HPLC for purity and by ESI mass spectrometry to confirm the molecular weight against the expected 4963.44 Da. A batch-linked Certificate of Analysis accompanies every vial and can be checked at /verify.
Is TB-500 the same as thymosin beta-4?
No — TB-500 is a synthetic peptide corresponding to the short active fragment of thymosin beta-4, not the full parent protein. This distinction is why identity confirmation by mass spectrometry matters when sourcing it.
Is TB-500 studied alongside BPC-157?
Yes — TB-500 and BPC-157 are frequently examined together in tissue-repair research because they act through different reported mechanisms. Sova also supplies them as a pre-mixed BPC-157 + TB-500 research blend.
