Tapering down on epi

[Tabascoonall]

Hey guys about to put in a order for some epi I will be running OL ep15tane 30/30/45/45/45/45 is it worth tapering down the last week to help prevent rebound. That is the only reason I haven't bought phs before Im scared of the rebound.
Thanks for your help. I'm here to learn so any help or guidance is welcome
