Thymosin Beta-4

Thymosin Beta-4 (TB-4) is a naturally occurring 43-amino acid peptide found in virtually all human and animal cells, with particularly high concentrations in platelets and white blood cells. It plays a crucial role in tissue repair, wound healing, and reducing inflammation. TB-4 works by promoting cell migration (including stem cells and endothelial cells), angiogenesis (formation of new blood vessels), and downregulating inflammatory cytokines. It also has cardioprotective and neuroprotective effects. Unlike TB-500, which is a synthetic fragment, Thymosin Beta-4 is the full-length peptide. It is being researched for its therapeutic potential in healing various injuries (muscle, tendon, ligament, skin, eye), treating cardiovascular conditions, and managing inflammatory diseases.
