The ITA reports that a sample collected during an in-competition testing mission on 13 December 2024 at the 2024 IWF World Championships, Manama, Bahrein from Jhohan David Sanguino Matamoros, a weightlifter from Venezuela, has returned an AAF ¹ for the prohibited steroid stanozolol metabolite stanozolol-N-glucuronide.
Stanozolol is prohibited under the 2024 and 2025 WADA Prohibited Lists as S1.1 Anabolic Androgenic Steroids (AAS). Stanozolol is a synthetic steroid analogous to testosterone with potent anabolic properties. Stanozolol is prohibited at all times (in- and out-of-competition) and is a non-specified substance.
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 IWF 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 IWF’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.
