Media statement: Skate athlete receives sanction - Henry Stogdale

21 March 2018

The Australian Sports Anti-Doping Authority (ASADA) today acknowledged the decision of World Skate to impose a one year ban on Australian athlete Henry Stogdale for the presence of a prohibited substance, as the result of using a supplement.

Mr Stogdale provided a sample on 8 September 2017 at the World Roller Games in Nanjing, China. The sample tested positive for 1,3-Dimethylbutylamine (DMBA) which is a stimulant banned in-competition under class S6.b of the World Anti-Doping Agency’s (WADA) 2017 Prohibited List.

The Doping Review Panel, convened by World Skate, considered the submissions of Mr Stogdale and found that the athlete did not intend to dope or cheat (reducing the maximum sanction from four years to two years) and that the athlete be given a reduction of sanction based on no significant fault or negligence.

The decision means Mr Stogdale is ineligible to participate, as an athlete or support person, in any sports that have adopted a World Anti-Doping Code compliant anti-doping policy until 1 December 2018.  

ASADA’s longstanding advice is that athletes can never be 100% certain that any supplement is free from prohibited substances. Supplement companies are not required to prove that their products are safe, effective or even accurately labelled.

ASADA has issued a number of warnings about DMBA and supplements more broadly, including advice that up to one in five Australian supplements contain prohibited substances, often not listed on labels.

To reduce their risk of testing positive, ASADA recommends athletes consider not taking supplements at all, or if required, that they choose low-risk products which have been batch tested by an independent  auditing company. Further information is available on the ASADA website:
