Critique my cycle: Test E, Test P, Dbol, Deca.

Hey guys,
Third Cycle

Planning on doing
Test E 500mg p/w
Test P 350mg p/w
Deca 400mg p/w
Dbol 30mg e/d

My only question is, I am running Dbol for 4 weeks to kickstart my cycle whilst my slow esthers take effect, now would it be advantageous to also jab the Test P whilst on Dbol, or wait for week 5 and switch from Dbol to Test P for the rest of my cycle.
Input please, thankyou.
