The WNBF UK adheres to the rules and guidance set out by the World Anti-Doping Agency and the World Natural Bodybuilding Federation. In and out of competition guidelines are based on the WADA Code. Athletes who compete in WNBF UK events should be natural bodybuilders. Any athlete who has previously taken performance and image enhancing drugs (PIEDs) should have abstained from their use for a minimum of 10 years, prior to taking part in a WNBF UK event.

Members should be mindful that some supplements may contain prohibited substances. Not all supplements are made with natural bodybuilders in mind. Athletes are responsible for any supplements/substances consumed. If you are unsure about the classification of any substances/compounds present in a supplement please consult the WADA code, reference against GLOBAL DRO, or contact the UK Anti-Doping Agency. Do not take any supplements or substances from a coach or friend, without first ensuring it is safe to do so. Ignorance is not considered a viable excuse under the WADA code.

Athletes who take part in WNBF UK events are subject to drug testing by biological sampling (urinalysis/ blood/ hair sampling). Pro Card winners and athletes competing at the UK Open International Championships / Supernaturals will also be subject to polygraph testing. Polygraph testing must be paid directly to the polygraph team. Urinalysis testing is covered in your membership fee. Testing can either be random, or targeted e.g. class winners. Failure to submit to a drug test will be considered a drug test failure.

It costs the WNBFUK £100 per athlete to send urinalysis away for testing. Independent polygraph testing is paid by the athlete. 

All members are subject to both in season and out of season testing. Non-active members are subject to out-of -season testing for 2 years from the date of joining the WNBF UK. Athletes must make themselves available for out-of-seasoning testing when requested. Athletes will submit to testing at an agreed upon location within 20 miles of the athlete’s residence/gymnasium. Failure to submit to out-of-season testing by either polygraph, or biological sampling (urinalysis/blood/hair sampling), will be treated as a drug test failure.

The WNBF UK may request an athlete report for multiple tests over the course of a season to create a biological passport. Athletes nominated to participate in a biological passport programme, must make themselves available for all tests at times specified by the drug control officer.

Any athletes who fail to pass a polygraph test will be suspended from WNBF UK events until they can subsequently pass a polygraph examination at a time and place specified by the event promoter.
Any athlete who fails the biological drug test will be suspended from the WNBF UK.
Athletes who refuse to make themselves available for drug testing either in season or out of season by polygraph or biological sampling will be suspended from the WNBF UK.

If you are currently using any medication which means you are in violation of the WADA code (insulin for example), you must contact the WNBF UK and apply for a TUE. If applying for a TUE you must provide a doctor’s note as evidence of the medications therapeutic use. All TUEs are dealt with on a case-by-case basis and whenever possible aims to take a common-sense approach to TUEs. Failure to apply for a TUE may result in a violation of the WNBF UK rules.

Members found to be trafficking, and/or prescribing PIEDs will be suspended from the WNBF UK. Any member found to be using PIEDS who is suspended will be considered a banned associate hereafter, any coaches working with athletes who are subsequently suspended will also be considered banned associates. WNBF UK Members should not work with banned associates.
