... Hmmm... If you are going to start taking d-bol you are probally trying to bulk up. In which case you would want to throw some other gear in there like test and eq or nor. But from the sounds of your post you shouldn't take anything because It seems that you don't know enough about gear in general.
If you are serious about doing some gear you really need to hang out on a discussion board for a while (like this one). Get yourself some litterature (anabolics 2002 is a good start). Learn as much as you can. There is so much more involved than just popping a couple pills and injecting yourself a couple times a week. You need to eat right, train right, sleep right, and do a lot of thins right in order for it to work properly.
So be patient, learn, and see if this is even right for you. Good luck bro.
