Barry Bonds indicted for perjury

What would have been the course of events if he admitted to using "clear" (tetrahydrogestrinone), the anabolic steroid that wouldn't be detected with routine tests for athletes? I read about this story in the book Game of Shadows.

Coincidentally, I  just read a book that had a chapter quoting several medical ethicists on the use of performing enhancing technologies. While "Shattered Nerves" is about neural prosthetics and the speculation that devices planted in the brain, eye or muscles might allow a person to have super-human abilities, it does raise the question about how we should deal with performance-enhancing technology in general.

Quoting Arthur Caplan, a medical ethicist, the author Victor Chase writes:

"To me the right stance is enhancement is acceptable if you can improve and enhance people's abilities, but they still retain the right to reject them."

Caplan was not talking about competitive sports, but even if you could achieve complete transparency about what athletes are doing to enhance their abilities, wouldn't this pressure the other competitors to do something similar or even more drastic?

Medical research will continue to provide breakthroughs that will enhance human performance, whether it be improving eyesight, hearing, muscle control, endurance, alertness, etc. Who will decide what is acceptable and what isn't. Will it be necessary to test all athletes on a routine basis as these technologies advance and become available?

It seems that indicting Bonds for perjury is peripheral to these question raised, but they do need to be answered nonetheless.
