Every year at the end of season, WADA updates the list of the prohibited substances with those who resulted to be doping after a long cycle of studies.
Some days ago the definitive list was published on the website of the World Anti-Doping Agency and it will be in effect for the whole 2017.
Among the most important modifies it is to note the explicit addition of the Higenamina among the Beta-2-Agonists, the substance which led to the positiveness of the racewalker Liu Hong and of the young thrower Konrad Bukowiecki.
Furthermore, Metilexaneamina was reported with its chemical composition: 4-methylhexan-2-amine.
Last but no least, it was underlined that it is possible to take extra oxygen via inhalation but not via injection.
