TB-500 Ban

Meaning

The TB-500 Ban refers to the official prohibition of the synthetic peptide Thymosin Beta-4 (TB-500) by major international sports and anti-doping organizations, most notably the World Anti-Doping Agency (WADA). TB-500 is classified as a prohibited substance due to its potential for performance enhancement, specifically its purported regenerative effects on muscle, tendon, and other tissues, which could provide an unfair advantage in competitive sports. This ban strictly restricts its use in professional and Olympic-level competition, regardless of its legal status in non-athletic, research, or therapeutic contexts. Clinicians must be aware of this classification when managing competitive athletes.
