You would take an AI without signs of gyno? Tren has ~0 aromatization due to the double bond on the 19th carbon (Androgenic substance). SO a test dose of 500 giving gyno? At the normal 3% rate and 69% test by weight (ester) you are looking at a whole whopping 10 mg of estrogen from conversion a week? Was the OP high estrogen naturally and gyno prone? If not he just put a bigfoot footprint on his E2 taking an AI when he did not need one.
Just my opinion.
