Do I Apply to WFDF or to My National Anti-Doping Organization?
It depends on your level. You're an International-Level Athlete for WFDF purposes if you compete at a WFDF World Championships or a WFDF Sanctioned Continental Championships, in senior or junior (U20 and U24) divisions. International-Level Athletes apply to WFDF. Everyone else, including Masters athletes, applies to their National Anti-Doping Organization (NADO).
Never apply to two organizations at once for the same substance and condition. If you already hold a TUE from your NADO, see "I Already Have a TUE From My NADO" below.
