Pierre, I think you're on to something there. I'm so glad I gave up the quest to be hyoooge years ago.
Robb, as you said, statins do decrease CoQ10 production. They also increase inflammation. I believe the author's point (which I believe is a mechanism borne from his own black box observations) is that due to the SAID principle, BBers muscles have adapted to a massive amount of inflammatory input, making it difficult to "damage" the muscles enough to promote hypertrophy (obviously only in high-level, drug-abusing pageant competitors). Thus the statins are brought in to add chemical damage to the muscle fibers--quite possibly by the exact mechanism you mentioned--reducing CoQ10 systemically. Too bad their cardiac muscle will (and likely already is) paying the price...
