The ITA, on behalf of the IWF, confirms that the athlete Louis Wayne Loic Gael Martinson has agreed¹ to the consequences for his anti-doping rule violation (ADRV).
The athlete tested positive for a metabolite of the prohibited substance GW1516 after providing a sample on 24 April 2025 during the 2025 IWF African Championships.
GW1516 is prohibited under the 2025 WADA Prohibited List as S4.4 Metabolic Modulators. It is a drug that activates pathways involved in fat metabolism in the body and that improves endurance performance. GW1516 is a non-specified substance prohibited at all times (in- and out-of-competition).
The athlete did not challenge his ADRV and agreed with the consequences proposed by the ITA. Accordingly, the case was resolved via an acceptance of consequences.
When notified of the case, the athlete was provisionally suspended with immediate effect.²
Due to his early admission of the anti-doping rule violation, the athlete was entitled to a one-year reduction of the otherwise four-year period of ineligibility usually imposed for an ADRV for the presence of a prohibited substance as set forth in article 10.8.1 of the IWF anti-doping rules.³
The athlete’s period of ineligibility is from 6 June 2025 until 5 June 2028. In addition, all the athlete’s individual competitive results from 24 April 2025 to the start of the period of ineligibility, including the results obtained at the 2025 IWF African Championships, are disqualified, including forfeiture of medals, points and prizes.
The decision may be challenged before the appeals division of the Court of Arbitration for Sport by the parties with a right of appeal in accordance with Article 13.2.3 of the IWF anti-doping rules.
The ITA will not comment further on this case.
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.
³ Article 10.8.1 of the IWF ADR (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, no further reduction in the period of Ineligibility is allowed.
