About TB-500

TB-500 is a name commonly used for a synthetic fragment associated with thymosin beta-4, a naturally occurring 43-amino-acid protein involved in actin regulation. Research on full-length thymosin beta-4 and related fragments has examined cell migration and repair biology, but those findings cannot automatically be attributed to every product called TB-500. The fragment's exact identity and its human effects remain uncertain, and robust clinical evidence for marketed TB-500 is lacking.

At a glance

Class

A synthetic peptide commonly described as the LKKTETQ segment (residues 17–23) of thymosin beta-4; the commercial name may not guarantee a uniform composition.

Studied mechanism

Thymosin beta-4 binds G-actin and is studied in cell-migration and repair biology; evidence for the full-length protein does not establish the same activity for every TB-500 preparation.

Evidence context

Much of the cited repair research concerns thymosin beta-4 or laboratory models; evidence directly establishing effects of marketed TB-500 in humans is sparse.

Blank arithmetic calculator

For independently verified inputs, concentration equals entered vial amount in mg divided by added liquid in mL. Entered requested mg divided by concentration gives mL; multiplying mL by the actual syringe markings per mL gives units. Enable JavaScript to use the calculator.
