TweetExcellent question Phil.
You've done great research.
By and large to be safe, get the nolva, this way you have it on hand just in case the PS cause some gyno symptoms. This way you can start preventative measures asap, and the if you won't if at end maybe maybe not use nolva.
Every now and then someone gets gyno with a PS, rare, yet it does, so better too be safe, and if you don't use it it always keeps for the future.
Good Luck
