OCB Pro Guidelines

OCB Pro Eligibility

Competitors are required to hold current OCB Pro memberships at all times. Competitors cannot have used any substance on the OCB banned list during the duration periods specified on the list.

Effective January 1, 2019, to be eligible for OCB pro contests, including the Yorton Cup, competitors must meet one of the following conditions:

  • Have won a pro-qualifying placement at an OCB amateur show (see full details).
  • Have placed first at another natural organization’s pro show that had 5 or more contestants in the class participated in and:
    • Can provide a lab report showing a urine test was passed at the event, and
    • Supplies contact information for the examiner who performed polygraph testing at the event so OCB can verify results.

Competitors who won a pro-qualifying placement with a natural organization other than OCB prior to 2019 are still considered eligible for OCB pro contests in cases where eligibility requirements in effect through 2018 were met (for Pro Open: there were at least 9 competitors (or 5 for Women’s Physique) in the division, and for Pro Masters Age 40+: there were at least 5 competitors in the division). 

Competitors who won a pro-qualifying placement in a Masters Age 40+ division are eligible only for OCB Pro Masters Age 40+ divisions. Competitors over the age of 40 who won a pro-qualifying placement in an Open division are considered eligible for both OCB Open and OCB Masters Age 40+ pro divisions.

Competitors who qualify as OCB pros for any category are considered eligible for all OCB pro categories of their gender. Competitors may not compete in more than one category at any given OCB show though.

After competitors compete in an OCB Pro Open division in a particular category, they are no longer considered eligible for that category in OCB amateur contests.

After competitors compete in an OCB Pro Masters Age 40+ division in a particular category, they are no longer considered eligible for that category in OCB amateur Masters Age divisions. If they haven't yet qualified for OCB Pro Open divisions, they may still compete in OCB amateur Open divisions. If they are competing at an event that offers a Pro Masters Age 40+ division, they may still compete in an amateur Open division in the same category at the same event. 

Competitors are not required to compete within a certain time frame in order to retain eligibility.

OCB Pro Cash Prizes

The 2019 minimum cash payouts at OCB Pro contests are $1,000 for 1st, $600 for 2nd, $400 for 3rd. Some shows may award higher amounts. Check a specific show's details for amounts pertaining to it.

Advertised cash prizes are guaranteed. The advertised amounts are not altered based on number of registrations or any other factors.

OCB Pro Yorton Cup Championships

The OCB Pro Yorton Cup is OCB's preeminent annual pro event. It's considered the top title within the organization (read the story behind the event). The OCB Pro Yorton Cup championships is awarding $3,000 for first place, $2,000 for second, and $1,000 for third for each division for 2019. To be eligible for the OCB Pro Yorton Cup, competitors must meet the OCB Pro Eligibility Guidelines listed above. Qualifying by winning a certain placement at another OCB Pro show held prior to this year's Yorton Cup is not required for 2019.

Drug Testing

The top three placement winners in every division must pass a urine test. All participants are required to pass polygraph screenings prior to competitions. OCB Pro shows require polygraph testing for all participants, for every show, regardless of how recently they may have been tested elsewhere.

Polygraph screenings are used since OCB events are 7 years drug-free for most substances. Many anabolic steroids are no longer detectable in urine within about 6 weeks of last use (some even less than that), and human growth hormone isn't screened for on standard sports panel anabolics tests.. Note: Approximately half who don’t pass the polygraph are bikini competitors. Banned substance use is not always about achieving greater muscle size... certain banned substances can yield an unfair advantage in getting leaner and shapelier.

Pro Categories & Divisions

OCB Pro categories offered are: Bikini, Figure, Men’s Bodybuilding, Men's Classic Physique, and Men’s & Women’s Physique. Divisions offered are Open and Masters Age 40+. Check a specific event's details to see which of the categories and divisions are offered at the particular event.


When divisions have more than one class, the majority of OCB events divide groups into as equal as possible parts by height based on total number of entries in a division. Formation of classes within divisions at a show is at a promoter's discretion though, and could sometimes be done by using specified height or weight ranges. Check a specific event's details to see which method will be used for a particular event.


Each judge takes all criteria for a category into account and assigns one overall score for each contestant in the form of rank during the group comparison rounds. A highest and lowest rank for each competitor is dropped as a safeguard against human error and/or bias, whether intentional or on a subconscious level. The remaining judges' placements are summed, and the competitor with the lowest sum total receives 1st place in the class. Second lowest sum receives 2nd place, and so on. In cases of ties, competitors ranked higher by the majority of all judges are awarded the higher placements (see video example). In cases of three-way ties, the head judge's scores are referenced to determine tie-breaking placements. Individual presentations are not factored into scoring but do count toward consideration for Best Poser awards when offered.
