I needed very little when my T was in the 700s. Just per week put my E2 in the 20s. But the ~/week that GeorgeCulp mentioned seems reasonable too. If you start noticing your elbow joints clicking a lot when doing bench or other exercises, it likely means you've overshot and need to lower your AI dosage (at least for me, that's always been an accurate litmus test). You'll likely get a nice boost to T as well, nothing huge, but I wouldn't be surprised if your numbers were in the 800s once you get your E2 in the 20s or even low 30s.
