About This Product
TB-400 is full-length Thymosin Beta-4 — the complete 43-amino-acid protein, not the shortened fragment sold as TB-500. Thymosin Beta-4 occurs in nearly every cell and in the fluid of healing wounds, and binds actin, the protein cells use to change shape and move.
The distinction matters when reading the literature: TB-500 is the 17–23 region synthesised on its own, while most published work describes the whole protein. The two are different molecules with different masses.
Each vial contains 10mg lyophilised powder. Our independent certificate is on file — its identity test confirms Thymosin Beta-4. The certificate number, batch and purity are shown in the Batch Verification card below, derived from the certificate itself.
