Dbol only isnt a great first cycle. Dbol, although powerful, its a drug that is generally used in addition to test. Test should be the base of all of your cycles. While running test, you can use less dbol and still get a great effect. This is a good thing because dbol is quite toxic and should only be run for short periods to avoid organ problems. 4-6 wks isnt going to allow you to gain a lot of keepable mass IMO. You should ideally run test e at 350-500mg for your first cycle, for 10 wks, with a small dose of an AI. It will be safer with less chance of quick onset side effects, plus you will make much better gains. Use a low dose of adex with it and you' be gtg.

No matter what the cycle, the foundation of your PCT will be similar. 2 wks after last shot, or if you end up still doing dbol only, the day after your last tab, you would take 40mg nolvadex for 1 wk and then 20 mg for the next 2 wks
