The ITA, on behalf of the International Bobsleigh and Skeleton Federation (IBSF), confirms that the athlete Arran Gulliver has agreed¹ to the consequences imposed for his anti-doping rule violation (ADRV).
The athlete tested positive for the prohibited steroid SARMS enobosarm (ostarine) after providing a sample during an out-of-competition testing mission on 2 March 2025.
SARMS enobosarm (ostarine) is prohibited under the WADA Prohibited List as S1.2 Other Anabolic Agents. It is prohibited at all times (in- and out-of-competition) and is classified as a non-specified substance. Ostarine, a selective androgen receptor modulator (SARM), may enhance performance by promoting lean muscle growth and improving strength.
The athlete did not challenge his ADRV and established that the anti-doping rule violation was not intentional. The athlete agreed with the consequences that apply, namely a period of ineligibility of two years from 24 March 2025 (date of provisional suspension) until 23 March 2027 and the disqualification of competitive results from 2 March 2025 onwards.
The relevant stakeholders, namely the World Anti-Doping Agency and UK Anti-Doping, have a right to appeal the consequences imposed before the appeals division of the Court of Arbitration for Sport.
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 IBSF 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 IBSF/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.
