Storage
TB-500 — written TB-500, TB 500, TB500 or TB500 peptide — is a synthetic analogue of the naturally occurring peptide Thymosin Beta-4. Buy TB500 5mg lyophilised at ≥98% HPLC, third-party CoA on every batch.
The range
Every vial in the range is lyophilised, labelled and lot-numbered the same way, with the certificate for its lot linked from its own product page. Pictured: BPC-157, TB-500, GHK-Cu, Glow and Retatrutide.
Browse the rangeTB-500 is a synthetic analogue of the active fragment of Thymosin Beta-4 (TB4), one of the body's most abundant actin-binding regenerative peptides. UK Peptides supplies TB-500 5mg lyophilised powder at ≥98% HPLC-UV verified purity, with a signed third-party Certificate of Analysis on every batch, dispatched same-day from Manchester via Royal Mail Tracked 24.
Published research has investigated TB-500 in wound-healing models, cardiac ischaemia and post-infarction repair studies, corneal regeneration, tendon and ligament recovery, neuroprotection in stroke models, hair follicle migration studies, and inflammation modulation in autoimmune research models. It is widely used alongside BPC-157 in comparative recovery-peptide research because the two compounds act through different but complementary regenerative pathways.
Store the lyophilised TB-500 vial at -20°C, sealed and protected from light. Once reconstituted, refrigerate at 2–8°C and use within 28 days. Do not refreeze after reconstitution.
Every TB-500 5mg vial is independently tested by an accredited independent laboratory to ≥98% HPLC-UV purity with mass-spectrometry identity confirmation against the published molecular weight of approximately 4,963 Da. The signed PDF Certificate of Analysis is supplied with every order and matches the lot number printed on the vial.

TB-500 is a synthetic peptide corresponding to a fragment of Thymosin Beta-4 (TMSB4X), a 43-residue actin-sequestering peptide first isolated from calf thymus in 1981 by Low, Hu and Goldstein. TB-500 is the C-terminal fragment most commonly studied in wound-healing and cardiac repair research.
