Super middleweight contender Jaime Munguia will not face any disciplinary action stemming from a positive drug test related to his unanimous decision win against Bruno Surace in their rematch on May 3.
Munguia tested positive for exogenous origin of testosterone metabolites — meaning testosterone that was from a source outside of his body, which is banned — in a urine sample given to the Voluntary Anti-Doping Association following his win against Surace on the Canelo Alvarez-William Scull undercard in Riyadh, Saudi Arabia.
Munguia, who is a former WBO junior middleweight titleholder, denied knowingly taking a banned substance and claimed the positive test was the result of contamination.
Those who investigated the matter, UK Anti-Doping and the WBC under its Clean Boxing Program, agreed the positive test was due to contamination.
“Independent analysis — including testing of my supplements by SMRTL Lab, a WADA-accredited laboratory that also processed my A and B samples, along with additional hair and nail testing by world-renowned Dr. Pascal Kitz — proved that the positive result was a false positive caused by accidental contamination with pregnenolone, a legal, non-banned substance,” Munguia said in a statement. “The levels detected were extremely low, provided no performance advantage, and were fully consistent with accidental exposure.”
