WADA prohibited list
/WAH-duh/
Also known as: WADA list, prohibited substances list, anti-doping list
Definition
The World Anti-Doping Agency (WADA) prohibited list identifies substances and methods prohibited in competitive sport. The list is published annually and divided into categories including anabolic agents, peptide hormones, beta-2 agonists, diuretics, and other substances deemed to provide unfair sporting advantage or pose health risks. Many peptide compounds are listed as prohibited substances because they can enhance athletic performance or recovery. For example, growth hormone, IGF-1, GHRH analogues, and some ghrelin receptor agonists appear on the WADA prohibited list. Athletes subject to WADA testing must not use these substances even in research contexts. The list reflects the consensus of anti-doping authorities about which compounds merit prohibition; inclusion on the WADA list does not necessarily mean a compound is unsafe for general use, but rather that it is controlled in sport due to performance enhancement concerns.
The WADA prohibited list applies to athletes competing in organizations that have adopted WADA codes, including Olympic sports, professional sports federations, and some amateur competitions. Athletes can request a therapeutic use exemption (TUE) if they have a medical need to use a prohibited substance, but approval is limited to medical conditions where no suitable alternative exists. The list is updated annually, with the TUE section specifying which prohibited substances can be used with appropriate medical justification and documentation.
Peptides appear prominently on the WADA list because of their potency and potential to enhance athletic performance. Even peptides under investigation in research contexts may be subject to WADA restrictions if they interact with performance-relevant biological systems (such as growth hormone regulation, muscle protein synthesis, or recovery). The distinction between research use and prohibited use can be important for athletes and researchers; a peptide compound may be under legitimate research investigation while simultaneously being prohibited in sport.
