Anastrozole / Arimidex Medicine Injectable Anti Estrogen Steroids No Side Effects
Anastrozole / Arimidex Medicine Injectable Anti Estrogen Steroids No Side Effects
Quick Detail:
Arimidex (anastrozole) is the aromatase inhibitor of choice. 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.
Description:
Anastrozole
Alias: Arimidex
CAS No: 120511-73-1
MF: C17H19N5
MW: 293.37
Applications:
High Purity Anastrozole/Arimidex/CAS No: 120511-73-1
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.
