UFC welterweight Elizeu Zaleski dos Santos has been suspended for one year by USADA after failing an out-of-competition drug test.
The 35-year-old Brazilian tested positive for ostarine, a selective androgen receptor modulator, on April 8. MMAFighting.com was first to report the positive test, which has not been yet been formally announced by USADA. Zaleski denies knowingly taking the banned substance, blaming the result on a contaminated supplement.
While Zaleski’s manager, Tiago Okamura, told MMAFighting that even though the supplement in question was identified, the compounding pharmacy that produced it denied responsiblility. As a result, dos Santos was unable to secure a reduced suspension from USADA.
