ABOUT The OCB

Founded in 2003, the OCB is the world’s largest all natural bodybuilding organization, hosting over 130 events yearly. OCB’s success comes from well-organized, fun competitions that prioritize drug testing, ethical judging practices, and professionalism.

OCB consistently screens all competitors before they step on stage, and conducts drug testing (lab reports provided) of all pro and amateur winners. Coupled with year-around drug testing, OCB is able to maintain a level playing field.

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.
