On Wednesday the United States Anti-Doping Agency (USADA) suspended former three-time UFC tittle challenger Chad Mendes for two years. The suspension stems from an out-of-competition drug test that Mendes failed back on May 17th.

According to the USADA Mendes tested positive for  “GHRP-6” which is a type of human growth hormone. The substance is considered “Non-Specified” on the World Anti-Doping Agency (WADA). As per policy any violation involving a non-specified substance warrens a minimum two-year suspension for first time violators. This is the first time that Mendes has failed a drug test while in the UFC.

Mendes (17-4) last fought in December of 2015. He was knocked out by Frankie Edgar in the first round of their main event bout. Prior to that he was knocked out by Conor McGregor when he took the fight on short notice. Mendes has had a bit of a rough patch as he only recorded two wins in his last five bouts. His suspension is retroactive to June 10, 2016. Mendes will be eligible to fight again in 2018. He will be 33-years old by the time he returns.
