Critique My Cycle: Test E, Test P, Deca, Dbol

Hey guys,
Third cycle.

Was thinking of something along the lines of

Test E 500mg p/w
Test P 350mg p/w
Deca 400mg p/w
Dbol 4 weeks 30mg p/d
Letro everyday
Nolva PCT

I’m debating on whether or not to throw in the Test P until week 5, as I will only be taking Dbol for the first 4 weeks to bring on the gains quicker while the slow esthers take effect.

Would it be more advantageous to take Test P with the Dbol straight from the get go? Or wait till week 5 then introduce it?
Input please.
