Well, I just finished a sust/d-bol cycle but my opinion will vary from everyone else's just a bit. I did the recommended 30 mg d-bol ED and 500 mg sust/week. The 500 mg sust gave me really bad fevers once a week. The sust flu wasn't in my head like everyone says it is. It was a weekly 100+ fever for me. Also, the sust shot hurt like gunshot wounds for a couple of days for me.
The 30 mg d-bol ED made me sick to my stomach and killed my appetite. I actually started to lose weight while on d-bol because I couldn't eat.
My opinions:
If you want to do d-bol, run it at 15 mg ED.
I wouldn't do sust again. I'd do primo instead, especially for my first time.
Not sure if this would work, but if you're set on sust (or already have a bunch) I'd stack it at 250 mg/wk with 200-300 mg/wk of deca or primo.
