Brazil’s Douglas Silva de Andrade, who joined the UFC in 2017 and has remained a steady presence in the promotion’s bantamweight division, has been suspended following the use of a tainted supplement.
de Andrade (29-5), 39, has been hit with a six-month ban for violating the UFC’s Anti-Doping Policy, albeit not intentionally.
In a statement issued by the promotion and CSAD (Combat Sports Anti-Doping, the UFC’s drug testing body), it was revealed that de Andrade had tested positive for furosemide in an out of competition drug test collected on February 14, 2025. Furosemide is prohibited from use at all times under the UFC’s Anti-Doping Policy; Douglas Silva de Andrade was subsequently pulled from his fight with John Castaneda as a result, scheduled for just two weeks later.
During the investigation of his case, the bantamweight provided a dietary supplement that did not list furosemide on its label of listed ingredients, which later tested positive for furosemide in a test conducted by the Sport Medicine and Research Testing Laboratory (SMRTL) in Salt Lake City, Utah. An independently sourced sealed container of that same supplement also tested positive for the substance.
Although that would on the surface clear Douglas Silva de Andrade of having intentionally cheated, the supplement was not on the UFC’s approved supplement list. As a result, he’s still subject to a six-month suspension, backdated to February 28, 2025, when he was provisionally suspended.
CSAD has also forwarded their findings to the Nevada State Athletic Commission, who may issue their own sanction due to the fighter having had a bout scheduled in their jurisdiction at the time of the infraction.
