Testing is the backbone of our Federation
In the late 1980s, the World Natural Bodybuilding Federation (WNBF) was founded in the Empire State Building in New York City by Chen N Low with the goal of promoting drug-tested bodybuilding events worldwide. Mr. Low and his publication Natural Bodybuilding & Fitness Magazine launched Natural Bodybuilding as it is known today!
All WNBF competitors underwent both polygraph and WADA compliant urinalysis testing at every event which was the first of its kind in professional athletics. The WNBF continues to lead by this example Worldwide in over 60 countries.
The integrity of our testing and following the WADA banned substance list is known and respected worldwide as solely that of the World Natural Bodybuilding Federation.
The WNBF supports event promoters, judges, and other agents of the sport to achieve these same goals. Seminars, classes, and training camps shall be promoted nationally to educate and inspire the rewards of attaining fitness goals naturally through the attributes of exercise and sound nutrition.
It is with pride that we can report every single member of the WNBF team; leaders, board members, promoters, athletes, and spectators all concur with and will continue to uphold this platform of drug-free athletics.
This testing is the backbone of our federation, and it will never be compromised! The WNBF aims to provide information to the bodybuilding and fitness population at large regarding the dangers of performance enhancing drugs in sport, and to provide a positive and fair competitive arena for its athletes around the world.
The WNBF sanctions Truly Natural bodybuilding and physique competitions throughout the United States of America with independent international affiliates who share our same ideals.
