The problem is that with the potential damage to the body and their career this is exactly what happens. Only the retired or mid performers are willing to actually take on the experiment. Top athletes already use some forms of doping but are very protective, since they have more to lose. Only those with nothing to lose will go all in on the enhancements.

I get the reasons for not doing it, but it seems clear that a lot of people are still doing it. Testing is always lagging the new methods of getting around it.

I'm curious if, with the world going crazy for LLM's, we will see it used to make novel compositions of existing chemicals that constantly outpace the labs tasked with finding the doping.
