^you don't have to space it out, you're not understanding half-lives correctly.
with dbols half life being about 6 hours:
say you take 50mg at midday, at 6pm you still have 25mg, at midnight you still have 12.5mg at 6am you still have 6.25mg in your blood.
If you take 50mg split up over the dya you'll never get your blood levels as high as you did for the 12 hours or so immediately following the 50mg dose. I find it more effective to take the lot 1-2 hours pre-workout, since dbol is highly effective at lowering cortisol this seems to me the best way to take it, plus the pumps are sick.
