The full Canada answerNRPT in sport and the military
Whether NRPT is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status. Before you compete or get tested, look up NRPT by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.

- Global DRO (check a named product)
- USADA (US athletes)
- Operation Supplement Safety (US service members)
