Important Athlete Advisory: prohibited stimulants found in supplements

26 June 2014

The Australian Sports Anti-Doping Authority (ASADA) is advising all Australian athletes subject to in-competition doping control to be cautious of the supplements DS Craze, Mesomorph 2.0 and Viking Before Battle.

Laboratory analysis identified a batch of:

  • DS Craze contained a prohibited stimulant N,alpha-diethyl-benzeneethanamine (analysed late 2012).
  • Mesomorph 2.0 contained the prohibited stimulants Oxilofrine (also known as Methylsynephrine, Hydroxyephrine, and Oxyephrine), Phenpromethamine, and Beta-methylphenethylamine (chemical structure similar to amphetamine) (analysis results received in April 2014).

These prohibited substances ARE NOT ALWAYS listed on the supplement’s ingredient label.

The supplement Viking Before Battle, which is available in Australia, lists the substance Methyl Synepherine on the ingredients label. Despite the difference in spelling this substance is the same as the prohibited stimulant Methylsynephrine.

What are these substances?

These substances are classed as S6 stimulants on the Prohibited List and are prohibited in-competition.

Sporting bans involving these substances can range up to two-years.

N,alpha-diethyl-benzeneethanamine links to methamphetamine

In addition to being a prohibited substance in sport, the Australian Federal Police (AFP) considers N,alpha-diethyl-benzeneethanamine to be an analogue of the border controlled substance methamphetamine under the Criminal Code (C’wth). The product DS Craze is subject to seizure by the Australian Customs and Border Protection Service and, under existing arrangements between the agencies, will be referred to the AFP for investigation and prosecution action.

Oxilofrine could be in other supplements

Oxilofrine has been the subject of a number of reported positive tests worldwide and the substance’s synonym, Methylsynephrine is listed on the label (as Methyl Synepherine) of a supplement available in Australia called Viking Before Battle.

It has also been found in other supplements in Germany and Canada despite not being declared on the ingredient label. In these countries the supplements found to contain Oxilofrine make claims of extreme fat loss or increases in mental performance in their marketing.

What you need to do

ASADA cautions athletes who compete under an anti-doping policy to take extreme care with DS Craze,Mesomorph 2.0, Viking Before Battle and other supplements, particularly those claiming benefits such as fat loss or an increase in mental performance.

Read the ingredients label, does it say ‘proprietary blend’? If it does, there is no telling what has been added in the manufacturing process and this is the risk you take.

Athletes using supplements do so at their own risk because they can be contaminated with prohibited substances. Under the World Anti-Doping Code’s principle of strict liability, athletes are responsible for any substance found in their body.

Supplements continue to be the source of preventable anti-doping rule violations both in Australia and overseas, so understand the risks to your health, career and reputation these products present.

Because of supplement manufacturing processes can lead to their contents varying from batch to batch, ASADA cannot give any specific supplement the all clear.

Further information about supplements and the steps you can take to help minimise your risk is available on the ASADA website.
