A Closer Look at the Prohibited List
The Prohibited List details all substances and methods banned in-competition only and those banned at all times. However, athletes should note substances do not have to be specifically named to be included on the List.
At the end of some categories on the Prohibited List you will find the wording ‘and other substances with a similar chemical structure or similar biological effect(s)’. This means something similar to a stated banned substance can be deemed prohibited even if it is not named.
Always be wary of substances that may contain similar endings to a named banned substance. For example, you will have heard of the banned substance Testosterone, so substances ending in ‘one’ are likely to have a similar chemical structure. Make sure you ask if you are unsure about a product, substance or ingredient.
What are the Differences Between a Specified and Non-Specified Substance?
Specified substances are those that, if found to be present in an athlete’s bodily sample, may be more likely to have a credible, non-doping explanation.
Non-specified substances are those where there is no non-doping explanation for having these substances in an athlete’s system.
