If you have letro + nolva, then you are set. Follow the instructions per the link below. You should have zero questions after reading it b/c it is very thorough and covers the 3 different point in cycle time scenarios in which gyno could occur and also tells you the exact dosing protocol to use. Letro will be used to treat the gyno symptoms and the nolva will follow it after the gyno symptoms subside to prevent the estrogen rebound that occurs whenever an aromatase inhibitor is stopped.

If you want to take a preventative approach, I'd recommend .25mg letro e3days, but prepare your joints for the pain depending on what you are running for your cycle (they will hurt anyway). Start tapering the letro towards the end of the cycle (.25mg a week for instance) to downplay the estrogen rebound going into PCT and onto your SERM (nolva).
