It would make more sense to use the prop at the beginning to get T levels up quickly. If you it at the end, you'll have a drastic drop from high to nothing and that's not the best approach. You should start PCT when there's still an ample T level in the bloodstream, not when it's already down.
im i getting it wrong or are u saying he should start pct when he still haves some prop in the system, no?
im also gonna end my cycle whit prop, isnt that a good way to go?
