An updated List of Prohibited Substances and Methods will enter into force on 1 January 2026

On 1 January 2026, the updated List of Prohibited Substances and Methods will enter into force. We would like to draw your attention to the most important changes:

1. Prohibition of anabolic steroid esters
   It has been clarified that not only anabolic steroids are prohibited, but also their esters (S1.1).
2. Inclusion of carbon monoxide (CO) in prohibited methods
   The non-diagnostic use of carbon monoxide is now banned as it can increase erythropoiesis under certain conditions. The use of CO for diagnostic purposes is allowed.
3. Adjustment for long-acting glucocorticoids
   It has been explained that the use of long-release glucocorticoid preparations can result in detectable levels beyond the official washout period due to long-term systemic absorption.
4. Adding fladrafinil and flmodafinil to the list of banned stimulants
   These substances are included in group S6 as potent analogues of modafinil and adrafinil, marketed as supplements.
5. Adding new substances to the Prohibited List
   Pegmolesatide (EPO mimetic), ɑ-naphthoflavone (aromatase inhibitor) and BAM15 (AMPK activator) have been added as new examples of banned substances.
