The UFC anti-doping program became official on July 1, 2015, with the United States Anti-Doping Agency (USADA) conducting year-round, in- and out-of-competition drug testing in its entire roster. Four months after its start, the program still raises questions.
The UFC made its last trip of the year to Brazil on Nov. 7, the second visit to the country under the USADA program, and Anthony Birchak revealed on his Twitter page that he wasn’t tested by the Brazilian MMA Athletic Commission (CABMMA) or USADA before or after his loss to Thomas Almeida in Sao Paulo.
