Epiandrosterone is great for dry hard gains and 1-ad is good for strength and size, but is also drier than 4-ad as it doesn't aromatize to any degree. In a calorie deficient state of a cut they should do well in maintaining size and strength. I really like the epi and added it to a superdrol run recently. The epiandrosterone will also work well with combating lethargy and libido issues if they should try and rear their head. 30 days if fine, but you could run them longer if you wished. They are not methylated so you wouldn't have the liver concerns and such like some other compounds. As far as PCT goes, Arom-X is solid but you can put together any other kind if you wanted to as well. Or mix and match. I tend to mix and match a lot with things that I have on hand. Arom-X, various natty t-boosters and such you know.
