At that height and weight I have to think that you don't yet know how to train and eat to grow. If you use dbol at this stage you will lose anything that you gain. You'll get itchy nipples, increased blood pressure, back cramps, possibly with headaches, lethargy and a reduced will to train. You might find yourself unable even to take brisk walks or play sports due to cramping and then what little you do gain will just evaporate since you don't know how to eat nor train to keep it.
Take a look at the training forum and get a bulking diet in place and see what another six months or so does for you before thinking about dbol again. Good luck.
