What I am saying is that most people snoose to end cycles with fast acting esters so they can get on their PCT right away. with sust and deca...you should be able to start your PCT at the correct time for both drug sters to be clearing your system at roughly the same time...But if you use prop, the prop ester will be out of your system before the Deca will. In other words, the Deca will still be working for at least another week probably longer while the Test has stopped working.
If you want to use T-prop, the run it for 1 or 2 weeks past the last Deca injection and then start your PCT.
