I actually advocated this some time ago but now have changed my mind (not completely though) for the simple fact it can suppress estrogen too much causing a nasty rebound weeks and maybe months after (look at some Clomid studies and you'll see why). If you do you use it, I suggest using it in the beginning and tapering it just like you would Nolva but run Nolva for a week maybe 2 beyond that. I got into a discussion with Swale over at CEM and he would never advocate using an AI post cycle for the simple fact that you could have a bad rebound when all is stopped (he runs an HRT clinic if your not familiar). All this is theoretical since there really is no study using AI's during PCT (we have Nolva and Clomid studies) but since that discussion with Nandi and Swale some time ago, I agree it COULD have some nasty rebounds. Maybe using it for just the first week could provide some benefit. Remember full recover is usually many weeks, sometimes months after your cycle and high test levels 6 weeks after does not mean they will be high 3 months down the road.
