Michael Buckley, of Reno, Nevada, has been issued a four-year ban for failing an out-of-competition anti-doping test, USADA announced Friday.
The 41-year-old tested positive for an exogenous anabolic steroid, which was confirmed by carbon isotope ratio (CIR) analysis, anastrozole, LGD-4033, and ostarine. The sample collected was collected December 5, 2015.
Buckley finished fifth in the 2015 U.S. time trial national championships in the 40-44 age group. He also finished seventh in the criterium at nationals in Ogden, Utah.
His period of ineligibility began on January 20, 2016.
