What is TB-500?
Thymosin Beta-4 is a small protein that regulates actin, one of the key structural proteins of cells. TB-500 corresponds to the active region of that molecule, synthesized in the laboratory to make it easier to study. That is why it is usually described as a peptide related to cell motility and organization.
Research context
The preclinical literature on TB-500 and Thymosin Beta-4 has mainly explored angiogenesis, cell migration during repair and the recovery of tissues such as muscle and tendon, in animal and in vitro models.
These results belong to the field of research and do not imply demonstrated efficacy or safety in humans. TB-500 is not approved for human consumption and is sold only to researchers.
