Back in December of 2016, Josh Barnett was flagged by USADA for a positive out-of-competition test. It’s been 13 months since that happened, and not much at all has been said publicly about the situation. The one thing that did come out was Barnett saying he tested positive for ostarine, which has been found to be in tainted supplements that led to suspensions of other UFC fighters before.
In an interview with MMA Junkie, Barnett vented his frustrations with USADA and believes that aren’t conducting their business in the correct manor. As a result, he refuses to come to a settlement with them, and this leads him to believe he will receive a full four-year suspension for second-time offenders.
