The “B” Sample of former world champion Lucian Bute turned out positive, just like the “A” Sample. Bute tested positive for the banned substance Ostarine after his fight against Badou Jack on April 30 in Washington DC. He maintains he has never knowingly used illegal products throughout his career in professional boxing. To determine out what happened, his team had all the supplements he used analyzed and found that the problem was with a product identified as “Dynamite PM Night Fuel” prescribed to him by fitness trainer Angel Heredia that was supposed to be free from any illegal substances. The Bute Team says the supplement was contaminated in the lab that prepared it and they have the intention of suing that lab for damages. The details have been sent to the DC Commission. In the meantime, Bute is in training at the Grant Brothers Gym and ready to resume his career.
