I'd go with 4-500 tops test e or c. As far as an ai I'd get bloodwork weeks 5 or 6 and introduce an ai if yoir levels are way outta range.. I wouldn't just add an ai if you don't need it. I am a heavy converter so I know I gotta run an ai but my buddy runs 500 test and never had to use an ai..so let bloowork tell you if you need to dose an ai or not. Deff have on hand thou.
