Synthetic fragment of Thymosin Beta-4 that promotes tissue repair, reduces inflammation, and accelerates healing of muscle, tendon, and ligament injuries.
Overview
TB-500 is a synthetic version of the naturally occurring peptide Thymosin Beta-4, found in high concentrations at injury sites. It promotes actin regulation, cellular migration, and angiogenesis to accelerate tissue repair. TB-500 has been studied in equine and rodent models for its ability to heal tendons, heart tissue, skin wounds, and corneal injuries.
