The Tennessee Titans had to play the first four games of their season without one of their most important offensive players. Taylor Lewan was suspended four games due to having failed a drug test this offseason. Lewan stated he tested positive for Ostarine, but that he has never knowingly taken the substance. Oakland Athletics pitcher Frankie Montas was suspended for taking the same substance that showed up in Lewan's test. Both probably received this substance through supplements. Supplement manufacturers have placed this ingredient in their products and not list it on the label.
Ostarine is the trademarked name for a Selective Androgen Receptor Modulator (SARM) that is not approved for human consumption in the U.S., or in any other country. Research has shown that SARMs like Ostarine have fewer androgenic properties, meaning they have less influence on the development and balance of male hormones, including testosterone. While they are not yet approved for human use, SARMs are of interest to the medical community because they might be effective at treating different health conditions without resulting in the negative side effects of steroids. Ostarine is prohibited at all times under the World Anti-Doping Agency (WADA) Prohibited List.
