Doing my first cycle. its a 10 week cycle. On day 3.
Test Cypionate 300, 100mgs/eod
Tren E 200, 100mgs/eod

39
5'10"
155
12%BF

So my buddy Im doing this with told me to take Arimidex during the cycle, as thats what he does. After all my research, I decided to go with .5eod. There are so many conflicting and not enough answered questions for what Im looking for out there so wanted to ask.
A) Do i need to take Arimidex?
B) If so does this sound like the right dose?
c) What are the down sides of taking Arim during a cycle?
d) do i need it for PCT as well? (i got novladex for after)
E) Do I need anything else like Arim during my cycle?
