there are several reasons why someone would want to run a bridge. one reason being that they have been on a long time and fear experiencing a crash effect, or they are unlucky enough to be in the midst of a crash. if this has ever happened to anyone it is a very serious state of depression and some degree of confusion due to the dramatic hormone swings being experienced. what this indicates is someone came off too quickly, and needs more of a taper. now dbol is strong enough it can prevent this kind of crash, however it will also suppress to a large degree your natural recovery, and it is not testosterone which is what your body really needs, and it also converts to a very potent estrogen which will be even more suppressive. what does make the most sense for this situation, and which can be run right through a well designed PCT, with the least effect on natural T recovery, is proviron.
