TB-500 is a synthetic 43-amino-acid fragment of Thymosin Beta-4 (Tβ4), a naturally occurring protein found in highest concentrations at injury sites. Its core mechanism is G-actin sequestration — TB-500 binds monomeric actin to modulate the ratio of G-actin to F-actin, which drives cell migration, angiogenesis and new blood vessel formation. Research highlights include: promotion of keratinocyte and endothelial cell migration, upregulation of anti-inflammatory cytokines (IL-10), cardiac tissue protection after ischemic injury, and nerve regeneration in spinal cord models.
Unlike BPC-157, TB-500 shows particular efficacy in cardiac and systemic tissue regeneration models. Often combined with BPC-157 in preclinical recovery research. Lyophilized powder, 5 mg per vial, Janoshik-verified 99.0% purity.
