Do you think testing will catch even 50% of the PED users?
Since 1968 to 2020 there have been 422 athletes who got caught doping by failing a test.
I got that from this source:

Russian athletes got caught because of a scandal not because the tests work. The whole premise of the movie Icarus is that doping tests failed to catch doping violators.
Lance Armstrong passed almost every test but he got exposed by a teammate.
Most baseball users got outed vs caught by a doping test.
It is pretty clear Conor is doing steroids but I doubt he will be caught.
I think ADCC is doing the right thing by not testing. Some will do steroids some won't but unless you have UFC funds unlikely you can run a strong enough anti-doping program.
The only way is for a surprise ADCC announcement the day of the tournament saying "Hey we are testing"
