Considering pretty much every athlete who uses PEDs from Armstrong to Marion Jones to Palmiero adamantly denies it, the denial itself offers no comfort to me. Let's see where the evidence goes. In most of these cases, where there is smoke there is fire. To me, either there is a legitimate explanation that helps clears things up or there isn't. And the latter often leads to a slow drip of information that catches the athlete in a web of lies. Hopefully, that doesn't happen, but I would expect it would unravel pretty quickly if there is something to this.
Unfortunately, HGH is the tough thing to prove without all the tests and so forth. The lawyerly statement is to say you never took PEDs by defining PEDs as substances that were banned at the time you took them. So, without positive tests, an ongoing discovery of circumstantial evidence, even if inconclusive, will leave a dark cloud of suspicion that will be hard to shake.
