Sometimes just looking at the total mega doesn't give the most accurate picture when running something like primo compared to tren. I think many people like low dose test with primo because it is the look it gives. Full muscle belly with little water beneath the skin. When the test is higher it may take away from that look.
do not deploy the caber or arimidex until indication is present/sign of issue, dont just run the adex just as a precaution. the less the merrier (I think you mean adex) also i would drop it and go with exemestane better safety profile on LDL
