What is Clostebol?
According to drugs.ncats.io, Clostebol, the drug that Padres’ star Fernando Tatis Jr. was popped for is a testosterone steroid: “Clostebol is a synthetic anabolic-androgenic steroid, a derivative of the natural hormone testosterone. Clostebol is a Schedule III controlled substance used medically in topical ophthalmologic and dermatologic treatments. Due to potential use as a performance-enhancing drug, clostebol is banned by the World Anti-Doping Agency.”
On Friday it was announced that Tatis Jr. had been popped for the steroid and will be suspended 80 games as a result.
The future Hall of Famer released a statement after the news broke.
