Drug Description

Proviron by Bayer Schering is a steroid drug widely used in both traditional and sports medicine. It is used primarily by athletes as part of heavy steroids cycles to prevent side effects, because it has anti-estrogenic properties (as an aromatase inhibitor) and the ability to increase free testosterone (by reducing the function of sex hormone binding globulin).

At the base of the product, the active ingredient, Mesterolone, is a structural derivative of dihydrotestosterone, which determines its properties.

Bayer Proviron is primarily a moderately strong androgen (up to 150% of endogenous testosterone), and its anabolic effect is characterized as minimal (up to 40% of endogenous testosterone). This is a high-speed drug (up to 12-24 hours), therefore, to achieve optimal results, it is required to take it with a daily periodicity.
