Ruti Aga's Six-Year Ban: The Real Story Is a Knee Injury, a Forged Prescription, and a Verdict Bigger Than a Career

\[The statement went out around 2 p.m., naming an athlete who had won the 2026 Tokyo Marathon — but in Ruti Aga's case the question was never about a victory. It was about a slip of paper. According to the Athletics Integrity Unit (AIU), Aga has been banned for six years. The story collapses into two paragraphs: a sample taken after she won a half marathon in China in March came back positive for a prohibited substance; a knee injury was cited; a prescription was produced; and the investigation found that the "doctor" who wrote it was a family member with no medical registration, claiming to have used an "old prescription pad from a former workplace" — a clinic that explicitly disowned the document. This is where I stop, because the first lesson in this case is journalistic. Media reports described the substance as a "steroid." It is not. Methylprednisolone is a glucocorticoid, WADA Prohibited List class S9 — not an anabolic steroid under S1. The distinction is not semantic. S9 substances are prohibited in-competition only, and only by injection, oral or rectal routes. A therapeutic knee injection administered out-of-competition is legal, provided no residue is present at the time of the competition. "Took a steroid" and "did not clear the washout window" are entirely different charges with entirely different consequences.
