adex works well with test Enanthate?

25 years old. 5’10’’ 173 pounds and goal is to lean bulk
I’m about to start my first cycle using testosterone enanthate.
Wanted to get my Arimidex dose exactly where it needs to be so I don’t have any side effect problems or develop bitch tits.
500mgs test E is what I am planning
how much adex and when do I need to use it here?
