Ranked strawweight Jaqueline Amorim receives a six-month suspension following a positive test for Ostarine contamination.
Ranked UFC strawweight contender Jaqueline Amorim has received a suspension from the Combat Sports Anti-Doping agency following two failed drug tests.
The out-of-competition tests took place on July 29 and August 17, 2026, revealing the presence of the banned substance Ostarine in her biological system.
Both test failures count as a single violation, and officials determined the result stemmed from a tainted supplement, according to information published by mmamania.
Investigation findings and supplement contamination
During the official investigation, the 31-year-old athlete provided full and complete cooperation as defined under the UFC Anti-Doping Policy.
Anti-doping officials reviewed the available evidence and determined the findings were consistent with exposure to low-level Ostarine contamination rather than intentional use.
Key factors in this decision included her testing history, low detection levels, the use of uncertified dietary supplements, and the global prevalence of tainted products.
Suspension timeline and return to competition
Because the investigation proved a lack of performance advantage, Amorim avoided a standard one to two-year ban for traditional doping violations.
Her suspension officially began on a retroactive basis from the date of the second test on August 17, 2026, minimizing her time away from the Octagon.
With the six-month penalty applied, she will be officially eligible to return and compete in mixed martial arts events starting on February 17, 2027.
History of Ostarine cases in the UFC
The issue of tainted supplements involving Ostarine is a recurring challenge for mixed martial arts athletes competing under the promotion banner.
Notable figures previously affected by similar contamination cases include former champions Sean O'Malley, Nicco Montano, and Josh Barnett.
Other fighters such as Marvin Vettori and Daniel Rodriguez also faced brief suspensions, though such incidents can still damage fighter reputations and cause lost bouts.
