Endurance360® Passes U.S. Anti-Doping (USADA) Testing

Bret Crosby riding for Bicycles Plus Racing from Dallas, TX, was tested in-competition by USADA!

While using Endurance360, Bret was in a three-man break during the Masters 40+ 1/2/3 race at the Tulsa Tough Criterium.

In the end, it came down to a sprint finish. Crosby emerged the winner of the day, taking it on the line. The U.S. Anti-Doping Agency (USADA) was in attendance and Bret was required to report straight to doping control.

“They asked if I wanted to disclose anything I was taking at the time” Crosby told us. “I mentioned Endurance360”. Crosby had been having a real problem with severe muscle cramps and began taking Endurance360 to eliminate the issue.

After leaving doping control, Bret a bit nervous but still in good spirits approached Team Endurance360 captain Cameron Hoffman “This stuff better be clean or I'm gonna come find you!” Cameron assured him the product was safe.

Crosby then received a letter from USADA, dated August 1, 2016, stating they were pleased to inform him the results did not indicate the presence of any prohibited substance.

This validates the safety of Endurance360 through random in-competition testing.
