TB-500 is a synthetic analog of the naturally occurring peptide Thymosin Beta-4 (Tβ4), a 43-amino acid protein found in virtually all nucleated cells. It plays a central role in actin sequestration, cell migration, and the regulation of inflammation. Research has focused on TB-500’s potential in wound healing models, cardiac tissue repair, and neurological regeneration.

Key research areas include its interaction with actin-binding protein pathways, angiogenesis promotion, and anti-inflammatory cytokine modulation. Core Power Peptides supplies TB-500 at 99%+ purity, independently HPLC and MS/MS verified, with full COA documentation.
