Good Credibility
Not FDA ApprovedWADA Banned
TB-500 is a synthetic version of the naturally occurring peptide Thymosin Beta-4. It plays a role in cell migration, blood vessel formation, and tissue repair.
Mechanism of Action
Sequesters G-actin monomers to promote cell migration and wound healing. Upregulates actin polymerization and activates cardiac progenitor cells.
