Definitely stack something with the dbol. Dbol alone might make you blow up fast, but without something else added in there, you will more than likely lose about 90% of your gains within a month after you stop the cycle. Since you don't really want huge gains, stack it with some eq or deca, this will help to harden you up after you come off the dbol and help you keep alot more of your gains.
Run something like this:
week 1-4 25mg/day dbol
week 1-8 300 - 400mg deca or eq
clomid starting 2 weeks after last injection.
That should be good for about a 10 - 15 pound permanant gain, maybe a little more.
And do lots of research before you start anything.
