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 17,000 urine test results on file since 1989!
All INBF|WNBF athletes must be a minimum of 10 years drug-free of prescription/pharmaceutical hormones on the banned substance list, and 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 INBF or WNBF competition.
INBF and WNBF drug testing policies and procedures are compliant with the World Anti-Doping Agency (WADA) Prohibited List. This prohibited list and banned items and timeframes listed on this website are guides to determining athlete eligibility. IT IS THE ATHLETES RESPONSIBILITY TO CHECK AND ABIDE BY THESE LISTS AT ALL TIMES!
**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 two (2) years before joining the INBF/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 an INBF or WNBF membership, you are providing consent to the INBF/WNBF to urine drug test you at events and/or randomly in and out of season. Athletes who refuse a test will have membership privileges suspended indefinitely.
**In any form, including creams, gels, patches, pellets, and injections, for any reason, even if a physician prescribed, is strictly prohibited. No Exceptions!
Gas chromatography/mass spectrometry (GC/MS) equipment is used to determine Testosterone/Epitestosterone (T/E) Ratios. 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 percent 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.
Note: Athletes with an elevated T/E may be banned for 10 years to life even if additional IRMS/CIR testing is not conducted.
The presence of any banned substance in urine (i.e., nandrolone), no matter how it arrived there, is ruled as positive (Urine Test Failure)
Any and all prescription diuretics, even when physician prescribed, used for bodybuilding purposes are banned for (3) months prior to WNBF competitions.
** If an athlete possesses heart-related complications, a TUE may be issued for competition.
** Spironolactone that is prescribed for acne MAY NOT be used for 14 days prior to competing in any INBF | WNBF Event, No Exceptions!
Prescribed and non-prescribed clenbuterol usage will carry a two (2) Year ban time Frame for NEW athletes wanting to join the INBF/WNBF.

** Due to the abundance of supplements and pre-workout products containing DMAA and/or related compounds, there shall be a 30-day amnesty period before an athlete is eligible to compete in any INBF/WNBF event for the first time.
Stimulants/medications prescribed or non-prescribed used for bodybuilding and/or weight loss purposes are prohibited. Athletes who are physician-prescribed medications with a “stimulating” effect must have an active prescription and must notify promoters and the INBF|WNBF for a therapeutic use exemption (TUE). Additionally, these medications may never be abused. Stimulants or medications that produce similar physiological effects, even if not expressly listed here, are prohibited for use. Aggressive weight loss drugs are ineligible for a TUE.
