Iasmin Lucindo Bezerra: UFC Fighter Suspended for Doping Violation

Brazilian mixed martial artist Iasmin Lucindo Bezerra, of Fortaleza, has accepted a nine-month suspension from competition following a violation of the UFC Anti-Doping Policy (UFC ADP). The announcement from Combat Sports Anti-Doping (CSAD) detailed the circumstances surrounding the case, which stemmed from an out-of-competition sample collected on September 24, 2025, in Feira de Santana, Brazil.

Positive Test and Immediate Removal

The sample revealed the presence of mesterolone, a prohibited substance classified as an Anabolic Agent. As a result of this adverse finding, Lucindo Bezerra was immediately removed from a scheduled bout on December 13, 2025, in Las Vegas, Nevada.

Investigation Findings

CSAD’s investigation did not indicate intentional use of mesterolone for performance enhancement. Lucindo Bezerra fully cooperated with the investigation, providing documentation from a Brazilian pharmacy detailing compounded dietary supplements she had obtained. This documentation showed the pharmacy regularly compounded products containing mesterolone, raising the possibility of inadvertent contamination.

Did You Know? CSAD utilizes Drug Free Sport International (DFSI) for biological sample collections, with over 5,000 trained personnel worldwide.

Further supporting this possibility, Lucindo Bezerra had previously tested negative in August 2025 and October 2025 (in Abu Dhabi, UAE). The concentration of mesterolone found in the September sample was described as minimal. However, CSAD could not definitively link the finding to a contaminated supplement due to the athlete’s prior use of the supplements from the Brazilian pharmacy.

Suspension Details and Next Steps

Given the level of cooperation and the evidence suggesting unintentional exposure, CSAD imposed a nine-month period of ineligibility, beginning September 24, 2025, and concluding on June 24, 2026. The UFC regularly educates athletes about the risks associated with dietary supplements, particularly those compounded by pharmacies, especially in Brazil.

Expert Insight: The reduced suspension, despite a positive test, highlights the importance of athlete cooperation and the complexities of supplement contamination in anti-doping cases. It demonstrates a nuanced approach to enforcement when intent is not clearly established.

Because Lucindo Bezerra was publicly scheduled to compete in Las Vegas at the time of the adverse finding, CSAD has also provided the relevant data and evidence to the Nevada Athletic Commission for separate adjudication under their own regulations.
