Are you people kidding???
Athlete takes steroids, athlete takes diuretic to mask steroids but she had a prescription. Would you also have a prescription from a doctor to produce in case you tested positive, derrrrrr!
And just how do you expect that Vessey would have gained access to a prescription medication without a prescription? Maybe she has her own pharmaceutical lab?
Also, the level of canrenone she had on board was evidently not sufficient to produce the sort of diuresis necessary to effectively clear steroids from her system.
So, it appears that an honest mistake was most likely made. It happens.
