Sorry... I haven't used either, but it seems like more people are able to effectively cut, with minimal sides, using H-drol compounds. With that in mind, I think you could comfortably recomp with it. Also, H-drol has a longer half-life in the body, making it easier to dose at the minimal dosage and still have enough circulating in the body. Successful recomp/cutting cycles consisting of only 75mg per day are not uncommon. Overall H-drol postcycle should be a breeze.
Now regarding Epistane, although this is a good compound, its anti-estrogen traits are like a double-edge sword. The very thing that makes this compound so great is also causing some users to complain about joint pain and rebound gyno. In addition, since Epistane's half-life is shorter than H-drol's, a higher dose of Epi may be needed. In short, higher dosages = more sides. Lastly, from what I understand, Epistane compounds may have a very short shelf-life. I remember reading somewhere that after about 6 months to 1 year the compound might lose up to 50 percent of its original potency. I'm not sure how valid this is, but if true, then that just answered your question regarding stocking up.
Best of luck with your recomp cycle.
