Results of 2021 Pro Motocross USADA Testing

The U.S. Anti-Doping Agency (USADA) conducted in-competition anti-doping testing on 10 different athletes at the Spring Creek National this summer.  Three testing screens were conducted on each athlete:  Prohibited Substances, Erythropoietin (EPO or blood doping) and Carbon Isotope Ratio (CIR or testosterone).

MX Sports Pro Racing has been notified by USADA that all results were negative and that no further follow-up is required.

We appreciate the participation of our riders in this program.
