The full-length 43-amino-acid thymosin beta-4 peptide (vs the shorter TB-500 fragment) studied for tissue, cardiac and wound repair.
Mechanism of action
Actin-sequestering peptide that regulates the cytoskeleton, promoting cell migration, angiogenesis and tissue repair.
Research peptide — not approved. Human PK exists only for IV dosing (~0.5–2 h); subcutaneous half-life is an estimate.
