The problem with PEDs is that there is a spectrum of different substances with performance effects so it is kind of arbitrary what is considered "legal" and what isn't. Then you have TUE so some athletes can use a drug while others can't. Mechanical devices seem more clear-cut to me.

Now that gene-splicng is becoming mainstream, are they going to have to do DNA tests to determine if an athlete has an uninherited gene for better VO2max?
