'Now we understand why Team Sky never joined,' says MPCC doctor

The Mouvement Pour un Cyclisme Crédible (MPCC) was created in 2007 by a group of teams who were adamant that the UCI wasn’t doing enough to fight doping. They implemented a test for cortisol levels in 2009 and repeatedly asked the UCI and WADA to ban the use of corticosteroids. MPCC members agreed that riders with a low cortisol level would refrain from racing.
