You do not want to use Formestane if you are using D-Plex. D-Plex is a knock off/clone of AN's The ONE. A great compound nonetheless, but anyway, it is DHT...in essence you already will have your estrogen kept in check. Also, because formestane has a strong affinity for the 5a-reductase enzyme (DHT) it will reduce your DHT levels in the body by effectively competing with testosterone for the 5a-reductase so basically it is going to limit what D-Plex does for you considerably.
Honestly, you shouldn't be using any AI's if you are using a DHT compound.
