Can't tell ya what kind of androgens they use these day's but I believe shit like Methyltestosterone has a half life of 6 hours and have read that some get a half life of just over 2 hours with it. Power lifters use to use that shit all the time. Don't know if they still do. And who knows what scientists have put together these days. I'm guessing a Methyl-test adderall type drug would make you feel fucking great come show time...
The thing is that anyone who has ever used AAS knows that the effects aren't immediate. It takes weeks before you start to feel it working. It takes some time for blood levels to build up so it can do it's work, building muscle, which in itself is also a gradual process.
BBers and PL will take compounds like suspension and oral prior to a workout and/or training session, but to give an extra boost to an already off charts hormone level prior to maximal physical stress. But have a dramatic increase in hormones will not give you any objective increase in strength and performance. Meaning that giving yourself a huge extra blast of, say, TNE, is not going immediate stimulate strength and hypertrophy. It may increase performance because it may give you a mental boost and more glycogen retention. When Test is high you FEEL better and more energetic and intense but the same can be said for caffeine. There is no objective improvement in actual muscle development.
But Conte and Patrick Arnold knows their stuff so it's just something that remains to be seen.
