It's very confusing indeed.
Because the reality of it all is that DHT, test and estrogen are present in your body for a reason...aromitization occurs when you bring extrogenous testosterone into the body and your body aromatises that test into estrogen and further into dht in order to achieve homeostasis.
The goal is to manage, but not to kill off estrogen and dht, because those hormones are equally as important to proper function and health.
Hope this helps.
