Olympic 800m medalist Nijel Amos suspended for doping

The third fastest 800m runner of all time, Botswana’s Nijel Amos has been provisionally suspended ahead of this week’s World Championships, after the 2012 Olympic silver medallist tested positive for a banned metabolite, the Athletics Integrity Unit (AIU) said on Tuesday.

The drug found in the 28-year-old’s system was GW1516, which modifies how the body metabolizes fat, and which can boost endurance. An AIU press release said that the World Anti-Doping Agency (WADA) has also warned that it poses a health risk to athletes.

GW1516 was originally developed to treat obesity and diabetes, but is not approved for human use, since it was discovered to be carcinogenic. It is banned in and out of competition, and not eligible for Therapeutic Use Exemption (TUE). A USADA bulletin from 2019 says GW1516 is also sometimes known as cardarine or endurobol and has been found in some supplements, even though it is illegal. In 2017, there were 31 sanctions worldwide related to its use. 

The AIU collected the sample from Amos during an out-of-competition test on June 4. Amos was notified of the result while he was preparing for the World Championships in Eugene, Ore., where he was scheduled to compete in the heats of the 800m on July 20. He finished eighth in the 800m final at Tokyo 2020. At Rio in 2016, he failed to make it out of the heats.

Amos’s silver in the 800m from the London Olympics was Botswana’s first Olympic medal and ranks as the third-fastest 800m time ever (1:41.73) behind Kenya’s David Rudisha (1:40.91) and Wilson Kipketer (1:41.11).

Amos has spent his last six seasons training with Mark Rowland and the Nike Oregon Track Club. Rowland recently left the club to start a new role as a coach with the Athletics Canada West Hub.

The AIU says the length of his suspension will be determined at a later date.
