USADA announced on Wednesday that UFC athlete Augusto Montano , of Mexico City, Mexico, has tested positive for a prohibited substance, which was determined to have been ingested by him without fault or negligence. Montano, 31, tested positive for trace amounts of clenbuterol as the result of an out-of-competition urine sample he provided on May 19, 2016. Clenbuterol is an Anabolic Agent prohibited at all times under the UFC Anti-Doping Policy, which has adopted the World Anti-Doping Agency (WADA) Prohibited List. Consistent with numerous prior reported cases globally, the issue of illicit administration of clenbuterol to animals destined for food production can result in, under specific conditions, a positive sample from an athlete.
