Drug Testing Policies

Drug Testing has been a top priority with the INBF/WNBF for over 30 Years!

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 7,000 urine test results
on file in 2020!!

The use of drugs is strictly prohibited.

All INBF/WNBF athletes must be 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.

NEW AMATEUR COMPETITORS ONLY must have not used any pro-hormones for at least two (2) years before joining the INBF/WNBF for the first time.

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 the off season.  Athletes not abiding by this policy will be suspended indefinitely.


At no point may any athlete use a prescription more frequently or at higher doses than it was prescribed by their physician.  Medications may never be used for bodybuilding or weight loss purposes.  All prescriptions have to be up to date and a copy must be presented to promoters at all INBF/WNBF events.
