ABOUT The OCB

Founded in 2003, the OCB is the world’s largest natural bodybuilding organization, sanctioning 130+ drug-tested natural bodybuilding events annually. OCB is known for professional, well-run competitions that prioritize strict drug testing, ethical judging, and exceptional event productions.

All competitors are screened before competing, and all amateur and pro winners are drug tested, with reports provided. Combined with year-round drug testing, OCB ensures a level playing field and maintains its reputation as the leading all natural bodybuilding federation.

I’ve competed in many contests. The promoters of the OCB shows have been more organized and athlete oriented. They seem to go the extra mile when planning to make competitors feel appreciated and make their experiences fun and memorable.
