Prazeres, 38, tested positive for exogenous boldenone and its metabolite 5β-androst-1-en-17β-ol-3-one as the result of two out-of-competition urine samples he provided on March 9, 2019. Confirmation of the positive test was achieved through additional analysis using the sensitive isotope ratio mass spectrometry (GC/C/IRMS) method, which reported laboratory results consistent with the exogenous origin of boldenone. Boldenone is a non-Specified Substance in the class of Anabolic Agents and is prohibited at all times under the UFC Anti-Doping Policy and UFC Prohibited List.

Prazeres’ two-year period of ineligibility began on March 9, 2019, the date his positive samples were collected.

USADA conducts the year-round, independent anti-doping program for all UFC athletes. USADA is an independent, non-profit, non-governmental agency whose sole mission is to preserve the integrity of competition, inspire true sport, and protect the rights of clean athletes. In an effort to aid UFC athletes, as well as their support team members, in understanding the rules applicable to them, USADA provides comprehensive instruction on the UFC Anti-Doping Program website (https://UFC.USADA.org) regarding the testing process and prohibited substances, how to obtain permission to use a necessary medication, and the risks and dangers of taking supplements, as well as performance-enhancing and recreational drugs.

In addition, the agency manages a drug reference hotline, Drug Reference Online (https://UFC.GlobalDRO.com), conducts educational sessions, and proactively distributes a multitude of educational materials, such as the Prohibited List, easy-reference wallet cards, and periodic athlete alerts. Many of the resources available to athletes are provided in multiple languages, including Russian, Spanish, French, Portuguese, Korean, and Japanese.

Along with education and testing, robust anti-doping programs enable investigations stemming from tips and whistleblowers. USADA makes available a number of ways to report the abuse of performance-enhancing drugs in sport in an effort to protect clean athletes and promote clean competition. Any tip can be reported using the USADA Play Clean Tip Center, by email at playclean@usada.org, by phone at 1 877-Play Clean (1-877-752-9253), or by mail.
