I agree with golden muscle. I usually don't exceed 15-20 mg of dbol with my cycles. I ran dbol by itself back when I was young, I kept about 5lbs. now I run the dbol with an injectible, but I just can't believe that with proper training/dieting you can't make some appreciable gains with just dbol. Ofcourse, the gains won't be as good as if you were to use some test with it, but you'll have some gains. you just have to remember that the dbol will shut you down, so post cycle therapy (pct) is probably something you should look into.
do some more research on this subject, in fact, do a lot of research and make an informed decision.
