If you're taking an anti-E for the purpose of getting your boys back to work, take it after. If you're taking one (or an anti-aromatase) to reduce bloat or overall estrogen during a cycle, then you'd obviously take it during.
It sounds like you're mostly concerned with post-cycle recovery, so take it post-cycle, as the name implies

...From the way you're talking about it, though, I would do a little more homework on it. I'm not saying that to be getting on your case, but I think you'd be a lot happier with your results if you understood the how's and why's of it all.
