TB-500 is a synthetic version of the naturally occurring peptide Thymosin Beta-4, which is found in high concentrations in blood platelets and wound healing sites. It plays a central role in tissue building, repair, and protection.
One of its key mechanisms involves regulating actin — the protein that forms the structural basis of cells and is essential for cell migration and proliferation in healing tissue. Research has studied TB-500 for its roles in wound healing, muscle repair, and cardiac recovery.
TB-500 regulates the actin-sequestering protein thymosin beta-4, which promotes cell migration, proliferation, and differentiation at injury sites. It also promotes angiogenesis (new blood vessel formation) and reduces inflammation by downregulating inflammatory cytokines.
The research on TB-500 spans multiple decades and institutions. Studies have examined its effects in preclinical and clinical settings. Our Education Center contains curated summaries of the most relevant published literature. As with all research peptides, individual results vary and the evidence base continues to evolve.
The appropriate administration method, dosage, and protocol for TB-500 is determined through the BRAVO1 physician review process based on your individual health profile and wellness goals. Do not self-administer any peptide protocol without physician oversight.
