For good health, you should want the minimal amount of drugs to put you in the mid- to high-normal range for T.
Arimidex is not needed for all men. I use 100 mg of T cup and 1000 IU HCG three times per week and have no need for arimidex. My estradiol is in the 40's and I feel fine, no symptoms at all.
There are plenty of studies with HCG and test cyp. Use Pub Med.
