This question has come up a few times and I say the same thing why don't they add some test to the cycle. But it's up to you, if you decide to just take dbol only cycle you must remember mate that dbol plays very heavy on the liver so you would want some liver support through the cycle. Something like this.
Dbol 30-40mg 1-6 weeks
Liv52 or milk thistle for liver support
Nolvadex 20mg if sides start
Pct clomid 100-50mg for 2-3 weeks after cycle
