We got to make a difference between the right orals for your goals, and the good bulkers. Definitely, the most prominent bulkers are Dianabol and Anadrol. However, they bring along a ton of side effects, and their gains will greatly consist of water. Therefore, after the cycle you will lose much of the gains, which is not good. These orals need to be taken together with testosterone base in order to get a more solid musculature, which will be easier to keep after ending the cycle.
Therefore, my personal recommendation would be to use something like anavar or turinabol. Perhaps you won't get all that crazy mass, but you will keep a much bigger portion of the gains made on cycle, and there will be much less side effects to face. The cycle as suggested by @muskate is a really good one. In this cycle you can replace anavar with Turinabol, and will get the same results basically. Give it some thought.
