4-AD-EC + M

I just got a bottle of 4-AD-EC which I will be using in a week. I also got 3 bottles of M. My question is should I wait until I’m done with the 4-AD-EC until I start with the M, or should I start taking them both at the same time?

Since there is no estrogen conversion from the 4-AD, I think it would make the most sense to take M after your done with 4-AD since the vitex in M is a testosterone booster, which you might need after some suppression may occur with 4-AD.
