In recent months there have been a number of high-profile doping cases in different sports involving the prohibited substance methylhexaneamine.

Methylhexaneamine is increasingly being found in nutritional supplements, typically those that are designed to increase energy or aid weight loss. There is a risk that supplements could contain this or other prohibited substances even if the ingredients listed on the label do not appear on the World Anti-Doping Agency (WADA) prohibited list. This is because some prohibited substances are referred to on supplement labelling by different names.

Methylhexaneamine is known by many names, including: 1,3-dimethylamylamine, dimethylamylamine, dimethylpentylamine, DMAA, forthan, forthane, floradrene, geranamine and geranium oil.

Supplements are not prohibited in football, but many have been found to be contaminated with various prohibited substances. Players are therefore strongly advised to consult their club or national association medical staff before they take any supplement.

Players should always remember that they are responsible for anything that is in their body. This includes prohibited substances contained in supplements.
