“The major disease at this time is the fact that [hormone] treatment alone doesn’t really remove the advantage to a level you to you might point out that fairness might have been achieved,” Lundberg told Italian language broadcaster Deutsche Welle in an excellent July interviews. “And in actual fact, the latest IOC [Internationally Olympic Committee] claims your overriding purpose try, and you may stays, the brand new ensure out-of fair race. That’s what it is said within assistance. Therefore that’s the condition right now: They will not wade hands-in-give.”
