Athletes and coaches must understand anti-doping rules to avoid violations. Many peptides are prohibited in sport, and ignorance of the rules is not an acceptable defense.
The World Anti-Doping Code is the foundational document for anti-doping policies worldwide. National Anti-Doping Organizations (NADOs) like USADA, UKAD, and CCES implement the Code at the national level.
The WADA Prohibited List categorizes prohibited substances. Peptides primarily fall under:
1. **Strict liability**: Athletes are responsible for any substance found in their system, regardless of how it got there.
2. **Check every substance**: Use WADA's or your NADO's substance lookup tool before taking anything.
3. **Supplements carry risk**: Dietary supplements may contain undeclared prohibited substances.
4. **"Research peptides" are not exempt**: The labeling of a product does not affect whether the substance is prohibited.
5. **Document everything**: Keep records of all medications, supplements, and treatments.
If an athlete needs a prohibited peptide for a genuine medical condition (e.g., insulin for diabetes), they can apply for a TUE before using the substance. Requirements include:
Violations can result in suspension (typically 2–4 years for a first offense), disqualification of results, and financial penalties.
