Jaqueline Amorim Hit with Suspension for Ostarine

Jaqueline Amorim has been suspended six months after failing two out-of-competition drug tests for Ostarine, with the UFC-funded Combat Sports Anti-Doping agency ruling the positive results came from a tainted supplement rather than intentional doping.

CSAD confirmed Amorim tested positive on July 29 and August 17, 2026, and treated the two failed tests as a single violation. The agency's statement said CSAD determined that the findings were consistent with exposure to low-level ostarine contamination rather than intentional use. Investigators pointed to several factors behind that call, noting the finding relied on her testing history, the low levels of ostarine detected in both samples, her use of multiple dietary supplements that had not been third-party tested and certified, and the documented prevalence of ostarine contamination in dietary supplements worldwide. CSAD also said there was no indication Amorim gained any competitive edge from the exposure.

The suspension is backdated to the second positive test, meaning Amorim becomes eligible to compete again on February 17, 2027.

Why Amorim Only Got Six Months

Ostarine contamination cases have become a familiar pattern in the UFC's anti-doping program, and Amorim now joins a growing list of fighters cleared of intentional use but still sidelined. Several fighters have already failed drug tests due to Ostarine being found in tainted supplements through the years, including former UFC champions Sean O'Malley, Nicco Montano and Josh Barnett, along with other fighters like Marvin Vettori and Daniel Rodriguez. In each of those cases, the fighters were only suspended for a few months, instead of the typical year or two for true doping violations. The shorter bans reflect CSAD's growing comfort distinguishing accidental contamination from deliberate cheating, but the label still carries real cost. Failed tests can strip fighters of momentum, scrap scheduled bouts and cost them paydays, the kind of fallout serious enough that Barnett once pursued legal action and ultimately asked out of his UFC contract over the issue.

Amorim, 31, enters the suspension off one of the better stretches of her career. She is 5-2 inside the Octagon and is coming off a first-round armbar finish of Loma Lookboonmee last May, a result that had her building real momentum in a deep strawweight division.

What It Means for Her Next Fight and the Betting Markets

A six-month layoff is a bettable variable the moment Amorim's return is booked. Layoffs of that length rarely sink a fighter's form on their own, but oddsmakers and sportsbooks typically price in some rust for anyone returning from a suspension, especially against an opponent who has stayed active. Expect her first fight back to open with a slightly wider line than her finish over Lookboonmee would otherwise justify, with the number likely tightening as fight week approaches and bettors get a clearer read on her camp and condition. Until a return bout is announced, there is no line to react to, but her strawweight stock shouldn't take a lasting hit given CSAD's contamination finding and her recent form heading into the suspension.
