sounds like you are worried about shutdown...
but your pct planned is.. 20mg nolva
you should think about that.. probably look into an AI and some HCG
go atleast 50mg ed on the prop IMO, the prop is so short estered EOD injects will not be good for blood levels, i have a picture of 50mg ed compared to 100mg eod..

incase you cant reaqd it the jagged line is eod inject while the solid line is ED..
now this is not exact science but it should give you an idea
also keep in mind due to the ester if you wanna move up in dose you just do it and youll see the results in 3 days tops and if its too much fo you to handle you drop it back down and yorue back to a low level in 3 days tops... in and out great fotr getting exactly where you wanna be
