This is why your supposed to research and plan out a cycle before you start. Not a flame but why would you order 1000 if you dont know what the sides are?
Any way as your question i wouldnt do dbols at the end of a cycle. Save them for another time or get ride of them up to you. Aslo i dont think there is a need to taper.

Do you have any anti-e's?
What about clomid?
