I'd run an anti aromatise full cycle. I am used to how my body reacts so I only use an anti estrogen like nolv upon painful or sensitive nips. You can feel them growing. There is a diffference between puffy nips and getting gyno, but if he is a newbie and doesn't know then I'd say maybe go with some nolv to be on the safe side, but if he's got some money i'd say go with some arim or femara because it will not hinder gains like some say nolv can. just my .02,,,bigjosh
