Bro what I think most guys do when it comes to the end of cycle using prop, they start it the last day or day after their last test 3 injection. If u are using test e u should wait 3 weeks to start PCT, during this 3 week time u can use prop, just stop it a couple days before your PCT, that is what I am thinking about doing for this cycle.

same dose (maybe a little less than 500 will do since prop has less more test and less ester but not by much) ED preferably EOD at most,also while using the test e 2x/week split, i use ED for prop and have been for a while now as much of a pain in the ass it is i notice alot less sides. when you start to hit around week 3-4 and feel the test e kick in, drop the prop and continue on, as for the end of cycle maybe someone more experienced in that technique could help you dicide what to do on that, just tryin to help, but im not an expert and there are much more experienced users than I here that could help you and most likely will
