Some useful background for those cycling fans in the audience trying to understand the context of Floyd’s test results. Turns out Malcolm Gladwell spent the necessary time getting on terms with the subject some years ago:
Athletes have now switched from injection to transdermal testosterone patches, which administer a continuous low-level dose of the hormone, smoothing over the old, incriminating spikes. The patch has another advantage: once you take it off, your testosterone level will drop rapidly, returning to normal, depending on the dose and the person, in as little as an hour. “It’s the peaks that get you caught,” says Don Catlin, who runs the U.C.L.A. Olympic Analytical Laboratory. “If you took a pill this morning and an unannounced test comes this afternoon, you’d better have a bottle of epitestosterone handy. But, if you are on the patch and you know your own pharmacokinetics, all you have to do is pull it off.” In other words, if you know how long it takes for you to get back under the legal limit and successfully stall the test for that period, you can probably pass the test. And if you don’t want to take that chance, you can just keep your testosterone below 6:1, which, by the way, still provides a whopping performance benefit.
