All banned substances and methods in Code-compliant sports are outlined in the Prohibited List. Substances and methods can be added to the Prohibited List at any time; however, it is updated as a minimum once a year, coming into effect on 1 January. As an organisation, we update our members with changes to the Prohibited List via our newsletter ahead of January 1st each year. As this list is updated frequently, athletes and athlete support personnel should make sure they check it regularly for any changes.
