Anabolic Steroids and Performance-Enhancing Drugs/Aromasin (Exemestane)




SZOB provides Aromasin (Exemestane) for years and lots of clients are surrounding with us. What is it and 

why? Control of estrogen levels is often necessary in anabolic steroids, due to aromatization of steroids such as 

testosterone, Dianabol, nandrolone (Deca), or boldenone (Equipoise.) In the aromatization process, the 

aromatase enzyme converts these androgens to estrogen. If this conversion is excessive, bloat, depression, 

loss of libido, impaired fat loss, or even gynecomastia can occur. An aromatase inhibitor (AI) is an effective way 

to solve this problem.


In contrast to Arimidex and letrozole which work by reversibly blocking access to the aromatase enzyme, 

Aromasin actually inactives individual enzyme molecules when it binds to them.


There is really neither advantage nor disadvantage to this different mode of action. As with all aromatase 

inhibitors, Aromasin should be dosed to achieve optimal estradiol levels, not the lowest possible levels. When 

dosed correctly and achieving the same estradiol levels, it doesn’t make a difference what inhibition mechanism 

was used.
