TB-500

Thymosin Beta-4

Also: Tβ4

animal studyin vitrohuman trial

A synthetic version of Thymosin Beta-4, a naturally occurring peptide found in virtually all human and animal cells. TB-500 promotes cell migration, blood vessel growth, and wound healing. Widely used in veterinary medicine and popular among athletes for injury recovery.

Upregulates actin, a cell-building protein critical for cell migration and proliferation. Promotes angiogenesis, reduces inflammation via downregulation of inflammatory cytokines, and supports stem cell maturation.
