Mesterolone

Proviron was created by a company known as Schering, who back in the 30s, was as big in the pharmaceutical industry as Apple is in the tech industry now. It was sold under a variety of different names at various times. Despite this, Proviron remained the most popular medicine, and it is still known by its original name, Proviron, even now.

During the 1970s and 1980s, bodybuilders began using proviron powder as a supplement with anti-aromatase properties. It is known that aromatizable drugs are responsible for fluid retention and gynecomastia. However, when used in combination with an anti-aromatase agent like mesterolone powder, the negative effects decrease.
