TB-500 (Thymosin Beta-4)

Thymosin Beta-4 is a 43-amino acid peptide that is present in virtually all human and animal cells. TB-500 is its synthetic counterpart, making this powerful repair molecule available for research applications.

The peptide's primary mechanism involves upregulation of actin, a cell-building protein essential for cell migration and proliferation. When tissue damage occurs, TB-500 promotes the migration of endothelial cells and keratinocytes to the injury site, accelerating the repair process.

TB-500 also reduces inflammation by decreasing pro-inflammatory cytokines and has been shown to promote hair regrowth by activating hair follicle stem cells. Its versatility across tissue types makes it one of the most broadly applicable regenerative peptides available.
