TB-500

TB-500 (10 mg) is a higher-dose research variant of the synthetic Thymosin Beta-4 fragment, designed for extended studies or multi-dose experimental protocols requiring larger quantities. This peptide is fundamentally involved in tissue regeneration pathways through its unique ability to sequester G-actin monomers, facilitating rapid actin polymerization necessary for cell migration and wound closure. The 10 mg format supports chronic administration studies, dose-escalation protocols, and multi-organ research where simultaneous investigation of cardiac, musculoskeletal, and dermal regeneration is desired. TB-500's mechanism includes upregulation of laminin-5, a key component of the basement membrane involved in cell adhesion and migration. Research has also identified its role in reducing oxidative stress markers and supporting mitochondrial function in damaged cells. The larger quantity per vial minimizes reconstitution events, maintaining compound integrity throughout extended experimental timelines.
