Cologne List

  • Nutritional supplements and products can contain banned substances.
  • Cologne List® is a list of nutritional supplements which have been tested for such substances.
  • By only using products which are on Cologne List® athletes reduce the risk of unintentionally becoming the victims of doping.
  • Cologne List® is not a recommendation to athletes that they should use a nutritional supplement. Our goal is solely
    to provide better information and to improve transparency!
