TB-500

TB-500 is a synthetic peptide, an active fragment (Ac-LKKTETQ) of the natural protein Thymosin Beta-4 (Tβ4), known for promoting cell migration, tissue repair (skin, heart, brain), angiogenesis (new blood vessels), and reducing inflammation, acting by binding to actin to support cell movement and tissue regeneration, often used in fitness and regenerative medicine for faster healing, though clinical evidence in humans for some claims remains limited.
