What is TB-500?
TB-500 is a synthetic version of the naturally occurring peptide Thymosin Beta-4 (TB4), which is present in virtually all human and animal cells. This peptide plays a crucial role in building new blood vessels, muscle tissue fibers, blood cell reproduction, and cell migration. TB-500 is known for its ability to promote endothelial and keratinocyte migration, which is particularly important in wound healing. Athletes and fitness enthusiasts often use TB-500 to promote recovery from injuries and to improve flexibility.
