The US Anti-Doping Agency (USADA) has banned USA Cycling National Team Sprint Coach and 2021 amateur Masters National Champion Brian Abers for one year after he failed a drug test and returned a positive test for Ibutamoren, a experimental banned drug that reportedly produces lean body mass and bigger muscles quickly.

The 56-year-old amateur cyclist from Colorado Springs, Colorado won the one kilometre time trial 16 September 2021, at the USA Cycling National Track Championships in the 55-59 age group and submitted an anti-doping control sample after the race. The sample came back positive for Ibutamoren, also known as MK-622.

At Abers’ USADA hearing he produce evidence that he had taken a dietary supplement that did not list Ibutamoren on the label, but the supplement did contain the banned drug when USADA had a sample analyzed at an accredited laboratory.

“The presence of an undisclosed prohibited substance in a product is regarded as contamination and the determination that an athlete’s positive test was caused by a contaminated product may result in a reduced sanction, as was the case here,” USADA announced.

USADA did not reveal the brand name of the supplement or if the analyzed sample came from Abers or was randomly purchased by USADA.

Abers has been stripped of his national title and all results after 16 September 2021, must return his USA stars and stripes national championship jersey and is banned from competition until 5 October 2022.

USA Cycling has not commented on the future role of Abers as USA National Team Sprint Coach, nor as a licensed coach offering private services via Brian’s House of Pain.
