TB-500 (Thymosin Beta-4)
Also known as: Thymosin β4 (Tβ4). Some “TB-500” products are a short Tβ4 fragment instead
"TB-500" is a trade name for thymosin beta-4, which regulates actin polymerization and cell migration relevant to tissue repair. PubMed indexes this compound under its scientific name — the literal term "TB-500" alone returns far fewer results, so this count uses the scientific name.
Research use only. Nothing here is medical advice; this compound is not approved for human consumption outside prescription use.
