Just dbol or are you stacking it with test?
I've never run a dbol only cycle, but when I run it with test I do it a little differently than the standard 'kickstart at the beginning' recommendation.
I've had more success running the test for 2-3 weeks, until I'm really feeling it and starting to put on weight, then I throw in the dbol at about 25mg day for two weeks (preworkout), then 50mg a day for two weeks split into am/pm doses. I've found that introducing the dbol after the test is making a noticeable impact leads to less rebound down in weight when I cut the dbol out.
I've run it as high as 75mg/day split into 3 doses, but get significantly more sides if I go above 50mg, so that's my ceiling now FWIW
