Contaminated supplement led to failed test, boxer Bute says

Former Montreal boxing champion Lucian Bute said a supplement he took to help him sleep contained the banned substance Ostarine and led to his positive doping test.
Bute intends to take legal action against the producers of the supplement.
He said Ostarine was not listed among the ingredients and that it might have accidentally got into the bottles. He said his physiotherapist, Angel Heredia, specifically ordered a product that did not contain banned substances.
The Romanian-Canadian intends to plead that he never knowing took a banned substance to the Washington Athletic Commission, which is to rule on whether he will be suspended.
Bute tested positive after fighting World Boxing Council super-middleweight champion Badou Jack to a majority draw on April 30 in Washington, D.C. Days later it was announced that his urine A sample tested positive. Results of the B sample received this week confirmed the positive test.
Bute held the International Boxing Federation super-middleweight title from 2007 to 2012. He said he intends to continue boxing, regardless of what the commission rules, in hope of regaining a world title one day.
