effect AAS

Most of the anabolic steroid not only dock to the androgen receptor, but also to the receptors for estradiol and progesterone. Knowledge about that is also relevant to steroids users, because the progestogenic and estrogenic effect of steroids tells us something about their possible side effects. In 2009 some Dutch researchers published a survey which might benefit health conscious steroids users.

The more you know about anabolic steroids, they more complex they seem to be.  If you start to study the chemistry of anabolic steroids you start to understand how various modifications are meant to prevent the conversion of steroids into estradiol-like and DHT-like hormones, while at the same time allowing for an increased anabolic effect. But if you understand that, you'll discover that it all works just a bit more complicated.
