Honestly, my gains were good on Dbol only, using 15-20mg ED, split into 3 daily doses, but I only ran it for 4-5 wks. Then I went to a "real" cycle, test cyp at 400mg EW for 10 wks and let me tell you, the results where much much better. I ran that first cycle, not knowing what I do now. If you want to give it a try, go for it, but believe me when I say, test is much better, even at low doses. Because of the toxic nature of orals, you don't want to make a habbit of doing oral only cycles. They are much harder on your body. So if you want to keep cycling, after this, consider test cyp or test e, for about 10-12 wks. As for an AI, yes, I think that Dbol has given gyno to more bodybuilders than any other compound. So I would take a little AI on this cycle. If you dose your dbol around 25mg ED, you can probably stay covered using .5mg adex 2-3x a wk, but you may find you need more. Everyone is different. You may also want to have some nolvadex on hand, in case you do start to get gyno. You can pop a couple nolva, which will kick estrogen off the receptor ASAP. And also increase the adex, to get estrogen under better control. 

Don't forget to do a PCT, which you can start 1 day after the last tabs of dbol. If you already have nolva on hand, you can use that. 40mg ED for 1 wk, Then 2 more wks at 20mg

Personally, I would highly suggest the dbol made by Geneza. I have been using it for several years and it's some wicked strong stuff. And unlike some other brands I have used in the past (which may have actually been M1T), GP doesn't effect my appetite 

Best of luck bro. Lift hard and be safe
