The ITA confirms that the athlete Jhohan David Sanguino Matamoros has agreed¹ to the consequences imposed for his anti-doping rule violation (ADRV).
The athlete tested positive for stanozolol metabolites in two in-competition samples collected on 28 November 2024 during the Bolivarian Games in Lima, Peru, under the testing and results management authority of the Organización Deportiva Bolivariana (ODEBO), and on 13 December 2024 during the IWF World Championships in Manama, Bahrain, by the ITA under the testing and results management authority of the IWF.
Stanozolol is listed under the WADA Prohibited List as S1.1 Anabolic Androgenic Steroids (AAS). It is classified as a non-specified substance and prohibited at all times (in- and out-of-competition). Stanozolol is a synthetic anabolic steroid that promotes lean muscle growth and enhances strength.
On 7 March 2025, when notified of the results of the 13 December 2024 sample, the athlete was provisionally suspended with immediate effect.²
On 26 March 2026, ODEBO issued a decision concerning the 28 November 2024 sample, confirming that the athlete had committed an ADRV and referring the matter to the ITA for determination of the applicable consequences under the IWF ADR.
Pursuant to Article 10.9.3.1 of the IWF ADR, the two adverse analytical findings were considered together as one single first violation.
The athlete did not challenge the ADRV and agreed with the consequences that apply under the IWF anti-doping rules as proposed by the ITA. Accordingly, the case was resolved via an acceptance of consequences.
Due to his early admission of the ADRV, the athlete was entitled to a one-year reduction of the applicable period of ineligibility as set forth in article 10.8.1 of the IWF anti-doping rules.³
¹ Athletes have the right to choose not to have their case referred to a hearing panel. In these instances, the anti-doping organisation will assess the athlete’s case file and establish the applicable consequences pursuant to the anti-doping rules and the athlete will have the right to accept the proposed consequences. If the athlete refuses the proposed consequences, the case is transferred to a hearing panel. This resolution mechanism is provided for in articles 8.3.1 and 8.3.3 of the IWF Anti-Doping Rules and 8.3 of the World Anti-Doping Code and is commonly referred to as an agreement on consequences and is deemed an IWF/ITA decision. The athlete’s National Anti-Doping Organisation and the World Anti-Doping Agency have the right to appeal the agreement on consequences before the competent appeal body.
² The information about the provisional suspension was publicly disclosed by the ITA shortly after its imposition: The ITA notifies weightlifter Jhohan David Sanguino Matamoros of an apparent anti-doping rule violation – International Testing Agency
³ Article 10.8.1 of the IWF anti-doping rules (and World Anti-Doping Code) provides for a one-year reduction for certain ADRVs based on early admission and acceptance of sanction. This applies where an athlete after being notified by IWF/ITA of a potential ADRV that carries an asserted period of Ineligibility of four (4) or more years, admits the violation and accepts the asserted period of Ineligibility no later than twenty (20) days after receiving notice of an ADRV charge. Where the athlete receives the one-year reduction under Article 10.8.1 of the IWF anti-doping rules, no further reduction in the period of Ineligibility is allowed.
