For me, the only time I ever get acne is when I was on Deca. Taking some Retin-A will help clear it up, but I'd recommend using it post cycle. Accutane is hard on your liver, and doxicycline is an antibiotic (bad for
protein synthesis-from my understanding). If I were you, I'd just take the Sust/Dbol since it's your first-you'll grow like a mother f@#ker. Especially since it's cutting season-I'm sure you don't want the extra water ret. Deca brings to the table-400mg Deca is on the low side anywho-save it for when you have some experience under your belt.
