The ITA reports that a sample collected from Lazizbek Mullojonov, a boxer from Uzbekistan, during an out-of-competition doping control on 11 June 2025 has returned an AAF¹ for methasterone metabolites.
Methasterone is prohibited under the WADA Prohibited List as S1.1 Anabolic Androgenic Steroids. Methasterone is prohibited at all times (in- and out-of-competition) and is a non-specified substance. Methasterone is a synthetic anabolic-androgenic steroid associated with the promotion of rapid muscle growth, increased strength and power.
The athlete has been informed of the case and has the right to request the analysis of the B-sample.
If the B-sample analysis is requested and confirms the result of the A-sample, the case will be considered as a confirmed anti-doping rule violation. If the B-sample analysis is not requested, the case will also go ahead as a confirmed anti-doping rule violation. The athlete will have the opportunity to present his explanations for the result.
Further, in accordance with the World Anti-Doping Code and article 7.4.1 of the World Boxing anti-doping rules, a mandatory provisional suspension has been imposed on the athlete. The athlete has the right to challenge the provisional suspension and ask for its lifting.
Pursuant to the World Boxing’s delegation of its anti-doping program to the ITA, the prosecution of the case is being handled entirely by the ITA. Given that the case is underway, there will be no further comments made.
