World Athletics 2022 WA vs Esther Macharia

In February 2023 the Athletics Integrity Unit (AIU) on behalf of World Athletics has reported an anti-doping rule violation against the Kenyan Athlete Esther Macharia after her sample tested positive for the prohibited substance Testosterone and its Adiols.

Following notification a provisional suspension was ordered. In her submissions the Athlete denied the intentional use of the substance. She admitted, without corroborating evidence, that a friend had administered Sustanon (containing Testosterone) as treatment for her joint pain.

Hereafter the Athlete failed to respond to the AIU communications. Ultimately in April 2023 she also failed to sign and submit the Admission of Anti-Doping Rule Violations and Acceptance of Consequences Form within the given deadline.

The AIU finds that the presence of a prohibited substance has been established in the Athlete's sample and accordingly that she committed an anti-doping rule violation. Further the AIU deems that she failed to demonstrate that the violation was not intentional.

Therefore the AIU decides on 3 May 2023 to impose a 4 year period of ineligibility on the Athlete, starting on the date of the provisional suspension, i.e. on 21 February 2023.
