You don't need to run any AI, in fact in can be detrimental.
If you are concerned about Gyno, which should be non existant at that dose, take some 10-20 mg of Tamoxifen a day, it won't lower your estrogen but it will bind to receptors in your chest, that way you get the benefit of estrogen and you don't get Gyno. I believe that it is a very bad idea trying to lower your estrogen at that dose of test.
