SD will put on more mass if that is the main thing that you are looking for. Here is a comparison from someone (Dr. D) who has done both.
Epi is much nicer emotionally. Also, the strength gains are simply outstanding. It's a better libido supporter and boosts it all the way though a 6 wk run, but more androgenic than superdrol as you may guess. No prostate or hair loss issues for me, but a little acne at higher doses. Blood values looked great. Cholesterol barely moved and enzymes doubled but where still under 60. No hypo with this compound and a great anti-depressant effect.
superdrol is a better carb loader and the gains are almost as hard and equally as dry as Epi, but SD can promote some emotional instability with me too. Remember when I commandeered the cherry picker from the construction site? Yeah, that was on my alpha run of SD! I won't go there right now (lol). SD never gave me a pimple though, not one. I guess that's the trade off for the libido. SD was also harsher on lipids, though still not bad and about equal on liver enzymes.
Overall, 20mg superdrol compares equally to about 40mg Epi, so quantitatively speaking SD is better, but qualitatively I prefer Epi. It's really an anti-e and guys are reporting good pre-existing gyno reduction with very, very few sides even at 30-40mg. I have a "pulse" protocol up at the IBE board on the Epi sticky that I employed first as a teen to avoid shutdown and the need for post cycle therapy. A lot of guys are trying it and logging results if you're interested. I still like SD because to me it was very clean, but this Epi is more versatile and the results are solid. If you're gyno prone or trying to treat gyno, it's worth a shot before you decide on surgery. Also, if you're in it for the strength it's hard to beat this one.
