Overview TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring peptide found in high concentrations in blood platelets and wound fluid. It is one of the most powerful healing peptides studied to date, known for its systemic reach — meaning it can travel through the body to promote repair far from the original site of administration.
Mechanism of Action TB-500 works primarily by upregulating actin, a protein essential for cell building and movement. By binding to actin and regulating its polymerization, TB-500 promotes cell migration to sites of injury, stimulates the formation of new blood vessels, and reduces inflammation. This multi-pathway approach makes it uniquely effective at accelerating both acute and chronic tissue repair.
Research Applications Research on TB-500 has focused on its role in healing muscle tears, tendon injuries, ligament damage, and cardiac tissue. It has also been studied for its anti-inflammatory properties, its ability to improve flexibility and reduce joint pain, and its potential in promoting hair regrowth. Its systemic action makes it particularly valuable in research involving widespread or hard-to-reach injuries.
Reconstitution & Storage TB-500 is supplied as a lyophilized powder. Reconstitute by adding bacteriostatic water slowly along the inner wall of the vial. Store unreconstituted vials in a cool, dry place or refrigerate for extended shelf life. Once reconstituted, refrigerate.
