From the above link:
"SARMs including enobosarm may be and have been used by athletes to assist in training and increase physical stamina and fitness, potentially producing effects similar to anabolic steroids. For this reason, SARMs were banned by the World Anti-Doping Agency in January 2008 despite no drugs from this class yet being in clinical use, and blood tests for all known SARMs have been developed.[11][12] There are a variety of known cases of doping in sports with enobosarm by professional athletes.[citation needed]
In May 2017, Dynamic Technical Formulations voluntarily recalled all lots of Tri-Ton, a dietary supplement that the FDA tested and found to contain enobosarm and andarine.[13]"
