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.
“It turns out that I inadvertently tool a medication to treat ringworm that contained Clostebol. I should have used the resources available to me in order to ensure that no banned substances were in what I took. I failed to do so.”
