TB-500 (Thymosin Beta-4 fragment) is a synthetic peptide derived from the naturally occurring Thymosin Beta-4 protein. It is studied for its potential role in tissue repair, cellular migration, and actin regulation, which are critical for wound healing and regenerative processes.

TB-500 is believed to promote angiogenesis, reduce inflammation, and enhance cellular motility, supporting the repair of muscles, tendons, ligaments, and skin. It is commonly researched for its possible effects on accelerated recovery, tissue regeneration, and overall structural integrity in experimental and preclinical models.
