I would personally taper an AI to your serm. You have to watch out for estrogen rebound after you've suppressed it for so long. Epistane doesn't cause gyno, but estrogen rebound afterwards can, even months after. I think it also depends on how sensitive you are to gyno / estrogen. A lot of people get away without an AI after epi, but I read more and more about estrogen rebound.
If you really want to cover you bases safely, I'd dose a little lower on the Torem, add in PCS, and throw in some Restore from ALRI as well for your ai/testbooster/cortisol support. Restore also deals with prolactin, not that it should be an issue after epi, but I've read of ppl with prolactin issues in general from it, just likely set off from having hormonal imbalance, and not necessarily only because of progestins.
