Overview

TB-500 is a synthetic version of a naturally occurring peptide called Thymosin Beta-4, which is present in virtually all human and animal cells. It plays a critical role in building new blood vessels, muscle tissue, and skin.

Mechanism of Action

TB-500 promotes actin upregulation — actin is a protein that forms the cytoskeleton of cells and is essential for cell migration and wound healing. It also promotes angiogenesis and has systemic anti-inflammatory effects.
