Overview
- Arcuschin provided a sample at the ITF M15 event in Lima on December 15, 2025, with the A sample indicating a stanozolol metabolite and the B sample on February 23 confirming the finding.
- Because stanozolol is classified as a non-specified prohibited substance, the Tennis Anti-Doping Programme mandates a provisional suspension.
- The International Tennis Integrity Agency notified Arcuschin on February 16, when the provisional suspension entered into force.
- The player may appeal to the president of an independent tribunal, but no appeal has been filed to date as his team reviews options.
- The 18-year-old, ranked around ATP No. 1940, did not compete in the second Tigre Challenger after receiving the notice.
