I really need some expert advice!

Iam going to start a cycle with
deca 200mg/week and test (testex) 250mg/week. i know i would probably be fine with the amount of 200mg/week deca, but i want to know if anyone have any experience with testex? i have heard from many that it is good stuff, but i dont know in what rate it converts to estrogen? would i be fine? or do i need something for it?

if so, what kind and when?

All testosterone converts to estrogen at 58% rate...i would still get something, nolvadex at 20mg ED or Arimidex at even .25mg per day should be fine...XXL
