TB 500 is a peptide identical in structure and function to Thymosin Beta-4. It
promotes substantial strength, endurance, and performance benefits in addition to
overall health and wellness in animals.  Produced by the thymus gland, it is a natural wound healing protein comprised of 43 amino acids. Also referred to as Tbeta4 and Tβ4, it has numerous cellular and physiological functions that facilitate rapid recovery and healing of damaged muscles, tendons, ligaments, and other bodily tissues.  As the major G-actin (globular actin) sequestering molecule in cells, TB4 stimulates
angiogenesis (the formation of new blood vessels), cell migration, stem cell
differentiation, and up-regulation of gene expression, along with promoting cell survival.  It exhibits profound protective effects on tissue in addition to its powerful repair and regenerative characteristics and has been shown to help prevent injury as well as speed up healing. TB-500 promotes enhanced performance, recovery, and wellness by facilitating wound healing, increasing flexibility, aiding in muscle and strength gain, and reducing inflammation. Increased muscle growth, muscle tone, and muscular endurance have all been observed as it stimulates the regeneration of cells in muscles, tendons, vital organs, and other tissues.
