Well... I've gained very well off of it. Took every dosage from 300 mgs a week to over 1,000 mgs a week. By itself, with test and d-bol... EQ is great for me.
If using it ALONE... I'd suggest 600 mgs a week. Frontload the first two weeks with 1200 mgs a week, then hit the 600 for the next 8. Clomid eod will keep any gyno away that might creep up on you. (it does with me), then follow up with regular post cycle clomid therapy... or kiss your sex drive goodbye.
