I'm ab to start 100/mg test cyp every 3.5 days. I'm hesistant about starting any anastrozole until I get my blood tested to see if I need it. How long should I take before getting my blood tested for estradiol after starting my injections? What symptoms should I be aware of indicating that my estradiol is too high and that I should start taking anastrozole? I know it varies from person to person, but what would be a good starting point if indeed I do need to start taking it? I've heard anywhere from .25 mg a week to 2.5 mg a week and all inbetween. I would assume that if its needed that the least amount required to be effective would be optimal. How long after starting X amount of anastrozole should I wait to be tested again for estrdiol levels?
