TB500

TB-500 is a synthetic, acetylated heptapeptide corresponding to the active fragment (amino acids 17–23) of the naturally occurring protein Thymosin Beta-4. It is studied in laboratory and in-vitro research for its role in actin binding and cell migration. TB-500 is sold by mypeptideslab exclusively for in-vitro research and is not approved by the EMA, FDA, or any national medicines authority.

In preclinical and in-vitro studies, TB-500 is investigated in relation to cell migration, tissue repair, and the formation of new blood vessels. Research focuses on the actin-binding properties of the fragment in study models of muscle, tendon, and cardiac tissue. To date, no completed controlled clinical studies in humans have been published.

The batch-specific CoA for TB-500 shows HPLC purity of 99% or higher, identity confirmation via mass spectrometry, the batch number, and the net peptide content in milligrams per vial. The CoA is published on the product page so you can review it before placing your order.

Every batch is HPLC-tested by an independent third-party laboratory to a purity of 99% or higher, with identity confirmation via mass spectrometry. The batch-specific Certificate of Analysis is published on every product page.
