Not a good idea in my opinion.
1) Gains made with dbol in the absence of testosterone tend to vanish as quickly as they appeared.
2) Your profile has you at 25% body fat. dbol tends to be bloating.
3) Such a small dosage will produce marginal effects at best, and may disrupt your natural production. That means if you don't do PCT, you may find yourself mentally and physically messed up until your body finds its way back to equilibrium. That includes libido disruption, depression, etc.
That said, it won't kill you. Why not profit from all of our trials and tribulations? Why fall into the newb pitfalls? This can all be avoided by reading the stickies (first 5 threads with little icon beside them) on the steroid forum. A couple hours of your time that is well worth it.
