Eric,
you need to do lots and lots of research. First of all, you need to be eating right. High protein, even higher carbs, and some essential fatty acids. Next, you have to train regularly, and you have to train right. To me it doesn't sound like you are very experienced in the weight room. Before you start any AAS, train for a few hard, intense years. You will be surprised how much you can actually gain. Make sure not to overtrain though...many newbies overtrain thinking they will get humongous -- more is not always better. Try to keep your workout schedule to around 4 maybe 5 days a week.
Now, if you decide you want to add some supplements that are legal, you should make sure to take a multivitamin every day. Also, you can go get yourself some creatine and protein powders. Glutamine could be helpful too.
You don't really sound like you know what you are doing when it comes to the dbol. First of all, you're on a dbol only cycle which already sucks. Next, you are on dbol for 8 straight weeks. I'm not sure what your dosage of it is, but do you realize the side effects of dbol?? 8 weeks is too long, and i feel quite sorry for your liver. Also, it doesn't sound like you have clomid for your post cycle, so you're pretty much gonna take most of your gains and throw them down the toilet.
If i were you I would quit the dbol all together, do a WHOLE LOT of research on training, dieting, supplementing...and if you decide to in the late late future, AAS. I'm pretty damn sure that if you start doing everything correctly, you will be pleased with the results.
