look at it like this.. INITIALLY you will get more size from dbol HOWEVER, you are not going to keep it, not that you keep them all with any steroid but being a lot will be water gain, it will dissipate... tbol is much cleaner with a great likelihood of keepability and less side effects with tbol equal less strain and a better recovery... if you are more geared towards instant gratification as opposed to long term keepability, then go with dbol but if you are more towards less sides, better recovery, cleaner gains and more sustainable gains, then go with tbol...
