estrogen levels during PCT

I'm on a prop cycle of 75mg ED for 10 weeks. After my last shot, how long does it take before my estrogen levels will go down? I'm running 20mg nolva ED throughout the cycle and for 2 weeks after my last shot, but would I be advised to run some arimidex at the end of my cycle to ensure no gyno, or would it be better to run nolva for another week or two instead?

bump . . . anyone know here?

thanks guys

start PCT 3 days after your last shot of prop, and run nolva all the way through cycle and pct
