You'll recover fine. LH and FSH should come back naturally within days of the end of the cycle, which is the purpose of SERM use anyway.
I would run the adex 0.25mg EOD throughout, and you could extend that for 3 weeks after, which may speed your recovery slightly.
Lowering oestrogen on cycle is generally a good idea since it's excessive oestrogen that seems to be most harmful to the testes - and thus makes recovery harder. Also take 5g of Taurine everyday (split dose), which should further help protect the testes.
Would you still recommend having a box of Clomid/Nolva on hand even if not using, just in case? Thank you.
