I will fight to defend my reputation

As you know, I have always taken a strong stand against drugs in sport. That's why it's obvious my test results are wrong. Yes, yes, I know I'm suddenly breaking records even after three lousy seasons and it did come out of nowhere, but I've simply been trying much harder lately. I decided to get more focused and I did. Anyway they tested me for testosterone, for God's sake. That's a natural substance! Okay, the levels, as measured, were abnormally high, but in my case they often are high, especially when I'm thinking about sex or showing off in front of women, both of which I do quite a lot.
So if sports drugs are supposed to be more prevalent than recreational drugs, who's taking them? Everyone denies it, including the ones who get caught. Well, I don't know who, just obviously not me.
