Ranked UFC strawweight Jaqueline Amorim has accepted a six-month suspension after testing positive for ostarine. The UFC’s anti-doping program, Combat Sports Anti-Doping (CSAD), concluded the positive was most likely caused by a contaminated supplement and did not reflect intentional use. CSAD announced the failed test and the suspension Friday, and the UFC posted its own statement on Amorim on UFC.com the same day. MMA Junkie first broke down the details.
The flagged samples came from two out-of-competition tests, one on July 29 and one on Aug. 17. In its statement, CSAD wrote that “after reviewing the evidence, CSAD determined that the findings were consistent with exposure to low-level ostarine contamination rather than intentional use.” Amorim becomes eligible to compete again on Feb. 17.
Ostarine is one of the most frequently flagged substances at the UFC level, and it has a long track record of turning up in contaminated food and supplements. Amorim has no previous drug testing issues on her record. As of publication, she had not commented publicly on the test or the suspension.

Where this leaves her
Amorim, 31, is 11-2 overall and 5-2 inside the UFC. She came over as a former IBJJF champion, and her UFC run has gone about the way you’d expect from someone with that pedigree. She strung together four straight wins before Mizuki Inoue beat her by unanimous decision. Amorim answered that loss in May, submitting Loma Lookboonmee with a first-round armbar.
That Lookboonmee win was a good reset. Lookboonmee is a Muay Thai fighter who wants the fight standing and at range, and Amorim made sure it never stayed there long enough to matter. Inoue managed to keep things on her terms over three rounds. Lookboonmee couldn’t, and the fight ended in the opening round.
If Amorim returns on the first day she’s eligible, she’ll have been out roughly nine months since the Lookboonmee fight. Nothing in the sources mentions a booking or a target date beyond Feb. 17.
Quick take
This is about as clean as a positive test gets. You have two out-of-competition samples showing low-level ostarine, no history of problems and an anti-doping body that looked at the evidence and decided she wasn’t cheating. Six months is a fair outcome. It still costs her, since a ranked strawweight coming off a first-round submission wants to stay active, and she’s now sitting out the back half of the year. Fighters should read this as a warning about the supplement cabinet. One bad tub of powder just cost a grappler with a 5-2 UFC record and real momentum most of a year. I’d expect the UFC to have her matched up quickly once February comes around, ideally against someone ranked who will test whether her top game holds up against a better wrestler than Lookboonmee.
