The List of Prohibited Substances and Methods, updated annually by the World Anti-Doping Agency (WADA), is the International Standard defining what is prohibited In-Competition and Out-of-Competition. The List also indicates whether particular substances are banned in specific sports. WADA reviews and updates the List annually and the most current edition of the List is posted on WADA’s website and IADO official website using the link below. The updated Prohibited List comes into effect on 1 January every year and everyone can access it.

Indonesia Anti-Doping Organization (IADO) does not recommend or advocate that athletes take supplements, as supplements are not subject to the same rigorous standards as pharmaceutical drugs. Supplements may contain impurities that are not specified on the label, and the impurities may contain prohibited substances.

Supplements are not strictly regulated in many countries, including Indonesia. The World Anti-Doping Agency (WADA) is also not involved in testing supplements. For this reason, IADO and other organizations, including WADA and IOC cannot “approve”, “endorse” or confirm the status of any supplement product. Athletes who test positive for a prohibited substance in a supplement may face the same penalties as someone who is deliberately using the essence to cheat.
