No, steroids are not allowed in Mr. Olympia competitions. The sport has strict regulations against the use of performance-enhancing drugs.
Commitment to a Drug-Free Sport
The International Federation of Bodybuilding (IFBB), the governing body for the Mr. Olympia competition, has taken a firm stance against the use of banned substances, including steroids. This commitment was formalized with the adoption of the World Anti-Doping Code in 2003.
Since then, the IFBB has continually worked to ensure that the sport remains free from steroids and other prohibited substances. This ongoing effort highlights the organization's dedication to fair play, athlete health, and maintaining the integrity of bodybuilding as a competitive sport. Athletes competing in Mr. Olympia are subject to drug testing to enforce these anti-doping policies.
