The only thing I can say is that im going through something similiar to you..So i stated what im trying and ill let you know the results..but your right, your own research coupled with others experience should result in a decision thats best for you
BTW heres some more infor on anastrozole::
Anastrozole (Arimidex®) is the aromatase inhibitor of choice. The drug is appropriately used when using substantial amounts of aromatizing steroids, or when one is prone to gynecomastia and using moderate amounts of such steroids. Arimidex does not have the side effects of aminoglutethimide (Cytadren®) and can achieve a high degree of estrogen blockade, much moreso than Cytadren®. It is possible to reduce estrogen too much with Arimidex, and for this reason blood tests, or less preferably salivary tests, should be taken after the first week of use to determine if the dosing is correct.
As an aromatase inhibitor, Arimidex's mechanism of action -- blocking conversion of aromatizable steroids to estrogen -- is in contrast to the mechanism of action of anti-estrogens such as clomiphene (Clomid®) or tamoxifen (Nolvadex®), which block estrogen receptors in some tissues, and activate estrogen receptors in others. During a cycle, if using Arimidex, there is generally no need to use Clomid as well, but (as mentioned in the section on Clomid) there may still be benefits to doing so.
