TB-500 and thymosin beta-4: know the distinction

Educational information only — not medical advice. This material cannot diagnose a condition, recommend treatment, or replace care from a qualified clinician who knows your history. The Peptide Center uses an evidence-first editorial process that prioritizes primary regulatory sources, trial registries, and peer-reviewed research; uncertainty and evidence limits should be part of every health claim.

TB-500 is a name used for products associated with fragments or analogues of thymosin beta-4. These marketed products are not FDA-approved therapies. Research involving thymosin beta-4 does not automatically establish the identity, quality, safety, or clinical benefit of a product sold under another name.
