If you have to ask if you should front load the answer is no.
Front loading spikes everything and if it is your first or 2nd or 3rd or what ever cycle you probably arent experienced enough to handle it or worry about it. (Speaking from experience.)
As you are a newbie and gonna do what ya want just make sure you dial in your arimidex dosage.
Ideal way is to get your E2 levels checked weekly and adjust your Arimidex dose to match.
Realisticly though: every time your nipples get puffy take 0.5mg until you find a dosage that works consistently (give it a few hours and dont exceed 1mg per day). Then once the test levels are balanced try to lower the arimidex.
