First of all, if you want to lose weight, you have to stay in a calorie deficit... and this doesn't go well with getting strong.
Nothing about the diet is mentioned in the plan, so I can't comment further.
Also, not that there are steroids for mass gaining and steroids for weight loss, however dbol isn't very well suited for your purpose.
There are products (non-steroidal) that can help you a lot in fat loss, much more than dbol.
why the choice of test prop? How many weeks will you follow this cycle?
will you take 2 orals one after the other? how long?
