I am running EQ at 600mg/wk, just finished the 4th week. I added in anavar this past week as well. This is my first cycle, and it is a cutting cycle, but i still gained 10lbs in the first 4 weeks while significantly dropping bf. I always had puffy nips from puberty and softer tissue underneath the nipples, so I assumed I would be predisposed to gyno and stocked up on nolva just in case. Towards the end of the 3rd week I noticed the tissue seemed enlarged. It wasn't painful or itchy, but it was enough to make me get on 25mg of nolva a day. It's fucked up, I never heard of gyno from EQ. It might have just been my paranoia, but I'm not taking any risks.
I would suggest getting nolva to keep on hand. There's no reason not to have it, it's cheap and you could use it in the future if you didn't use it now. You don't have to use it unless you see any symptoms, so you don't have to worry about hindering gains unless it's necessary to avoid gyno.
