Drug Testing Policies
Drug testing is our top priority
IT IS THE ATHLETES RESPONSIBILITY TO CHECK AND ABIDE BY THESE LISTS AT ALL TIMES!
The backbone of our reputation is the strict adherence to stringent drug testing. We place the highest importance on ensuring that athletes are drug-free so as to ensure fair competition at each and every event Worldwide. We are proud to announce that we have over 40,000 urine test results on file since 1989!
The use of drugs is strictly prohibited
All WNBF athletes must be a minimum of 10 years drug-free from all Anabolic Androgenic Agents, Peptides, HGH, Growth Hormones, and prescription/pharmaceutical hormones on the banned substance list. Minimum of two years free of over-the-counter hormones, pro-hormones, or banned substances listed or their chemical counterparts, unless otherwise noted, prior to their first WNBF competition. There may be different ban timeframes with select agents in a paticular class. Please read the entire banned substance list!NOTICE: As of January 2022, urine or polygraph drug test failures for anabolic-androgenic steroids, growth hormones, peptides, SARM's products, and use of other oral or injectable PEDs will incur a lifetime ban from WNBF membership privileges.

WNBF World Affiliate Drug Testing Rules
The following list of substances and related compounds are banned by the World Natural Bodybuilding Federation. Their use constitutes grounds for dismissal from WNBF competitions and suspension from membership privileges in the organization for a period of ten (10) Years To Life from the failure date
Please read all supplement ingredients carefully; athletes are responsible for being vigilant regarding their supplement usage.
NEW AMATEUR COMPETITORS ONLY must not have used any pro-hormones or SARM’s products for a minimum of five (5) years and DHEA & 7 keto DHEA two (2) before joining the WNBF for the first time. Over the counter banned supplement history will be evaluated on a one on one basis to determine eligibility and will be confirmed via polygraph examination.
Consent To Drug Testing
When an athlete purchases a WNBF membership, you are providing consent to the WNBF to urine or polygraph drug test you at events and/or randomly in and out of season. Athletes who refuse a test will have membership privileges terminated indefinitely.
Polygraph Testing Notice
We require all competitors to take and pass an intense polygraph test and in their own language. If an athlete does not speak the native language in a country they are competing in it is the athletes responsibility to inform the WNBF Affiliate Promoter of this language barrier, and they must hire professional translation services at their own expense.
This test is good for 6 weeks for amateurs and Pro’s. If you are entering another WNBF event within the 6 week timeframe please let the Affiliate/Promoter know you have been tested and they will confirm this with a WNBF official.
*WNBF athletes from all countries consent to be surprise polygraph tested in and out of season.
Prescription Medication Notice
At no point may any athlete use a prescription more frequently or at higher dosages than prescribed by their physician. Medications may never be used for bodybuilding or weight loss purposes. For prescription medications to be approved by the WNBF consulting physician please submit the following documentation;
(1) A copy of the physicians signed clinical note from the visit that documents a genetic disorder, hormone deficiency, or a significant injury and a diagnosis code that clearly demonstrates
(2) Within that same clinical note the physicians plan to prescribe the specific drug; then
(3) A copy of the physicians prescription – electronic or hardcopy – from that same visit for the abnormality/injury; and finally
(4) Copies of the documentation from the pharmacy that they indeed filled the prescription as written.
A simple physicians note will not be accepted or even reviewed. Only the legal documentation in a patient’s clinical chart is eligible for review.
Until all four (4) elements are provided there will be absolutely no review. Once we receive all four elements the documentation will be reviewed for consistency with respect to dates and diagnosis. All determinations are made on a case-by-case basis and there will be no comparisons between the documentation of one athlete to another.

Urine specimens in excess of a 4/1 ratio are red flagged and ruled as positive tests, no matter what the cause. In the event of elevated T/E results (which can occur naturally in a very small percentage of the population) further, testing will be done via IRMS/CIR to determine if exogenous testosterone is present in the urine. This will be done at the athlete’s expense via a WADA-accredited lab in Utah.
Athletes with an elevated T/E may be banned for 10 years to life even if additional IRMS/CIR testing is not conducted.
