There is quite a long wrong with your cycle. Here is a good video for you to watch on how to safely run a dbol only steroid cycle:

First, you need to add an AI to your cycle to keep estrogen in the low to normal range. This will prevent estrogen related side effects like gyno.
Second, you need a better PCT.
4 weeks really isn't a lot of time. I would personally do 6-8 weeks. This is what I recommend for a cycle:
Dbol or Tbol 30-50mg/day
Aromasin 10mg every other day or arimidex 0.5mg every other day
A good natural liver aid supplement like N2guard - 1 serving/day
A good natural testosterone booster like HCGenerate - 1 serving/day
After the cycle, it's important to run a proper mini PCT.
4 weeks of the following:
clomid at 25mg/day
nolvadex at 20mg/day
A good natural liver aid supplement like N2guard - 1 serving/day
A good natural testosterone booster like HCGenerate ES - 1 serving/day
