Letro use up to PCT?

How long should I continue Letro after my last injection of Test/Deca? Should it be continued up until the start of PCT (four weeks)? I don't believe that is correct. I have never used Letro before. There are many different opinions as far as tapering off because of estogen rebound. Right now I am using .5mg ED, but may bump to .75mg ED.

If this doesn't make sense please let me know and I will try to reword. Just short for time right now.

bump for answers

use the letro right up to pct... have nolva during pct to control estro rebound... continue letro after pct if necessary. If you continue after pct, make sure you taper it off with nolva again to prevent estrogen rebound.

I've been told to overlap the Nolvadex and Letro by 3 days to control rebound
I'll also be using Clomid during PCT, should i overlap this with the Letro too?
