I dunno.
To get to the Olympics through the IFBB, you have to pass a test to qualify. In my country, they've decided to introduce out of season random testing, but I don't think this is the norm. The IOC has a lot of 'qualifying' criteria for a sport to qualify, and this may include out of season (ie random) testing. All I know is that the majority of BBs in my country have swapped over to the completely non-tested federation, Olympics be damned. So I was not joking when I said that I may make it to the Olympics merely because no one else could make it through the minefield of drug testing!
