A synthetic seven-amino-acid acetylated peptide fragment derived from the parent protein Thymosin β-4. This review covers the published preclinical literature on cellular migration and tissue research, the analytical distinction between the synthetic fragment and the full-length parent protein, and the regulatory status across major jurisdictions including the WADA Prohibited List.
PRECLINICAL RESEARCH VECTORS & MECHANISMS
TB-500 research is heavily concentrated in the fields of sports science, cardiology, and soft-tissue recovery, leading to its high-profile inclusion on the WADA Prohibited List. The full dossier covers:
Actin Upregulation: The mechanism by which TB-500 binds to actin, regulating cell polymerization and driving cellular motility.
Endothelial Migration: In vitro studies tracking the rapid migration of keratinocytes and endothelial cells to sites of tissue damage.
Analytical Distinctions: The critical structural and analytical differences between the synthetic fragment and the full-length parent protein.
PROCUREMENT & COMPLIANCE PROTOCOL Strictly synthesized and supplied for in vitro research, analytical characterization, and laboratory mass spectrometry. Not for human use.
