Arimidex: Pre, during and post cycle questions

[BlueSteelBlue]

Hi guys, I'm preparing to start my first cycle at age 40 and I have the following questions:

1) Will it be beneficial to take Arimidex for 1 or two weeks to suppress aromatase before starting enanthate at 200mg per week for 10 weeks?

2) What is the recommended dose of Arimidex during the cycle? (I don't want the risk of developing gyno)

3) What is the recommended dose of Arimidex for PCT?

Thanks!
