TB-500
Thymosin Beta-4 fragment for tissue repair
TB-500 is a synthetic fraction of Thymosin Beta-4, a naturally occurring peptide present in virtually all human cells. It plays a critical role in tissue repair, cell migration, and inflammation control.
⚙️ Mechanism of Action
TB-500 promotes cell migration by upregulating actin, a cell-building protein. It also drives angiogenesis, reduces inflammation via downregulating inflammatory cytokines, and promotes stem cell differentiation.
