Mg per Mg, Dbol is much more effecient. 50 mgs of dbol a day will give you some real gains and some sides. 50mgs of Drol won't do much at all. Use tne nolv if you need but it will diminish your gains. Save some nolv for PCT as well. Normally I would never recommend a oral only cycle, but if your going to do it, this will give you your best results.
