An over-the-counter spray sold in Italy has caused No. 1-ranked tennis player Jannik Sinner to fail two drug tests in March. The spray, Trofodermin, contains the banned anabolic steroid Clostebol and is available without a prescription in Italy. The medication led to a trace amount of Clostebol showing up in Sinner's test results.
Trofodermin, meant for treating cuts and scrapes, comes with a warning in Italian that states the use of the drug without therapeutic needs constitutes doping and can result in positive anti-doping tests. The product is available for purchase at pharmacies in Italy for 14.50 euros ($16).
