Proviron is Bayer’s brand name for the oral androgen mesterolone (1-methyl dihydrotestosterone). Similar to dihydrotestosterone, mesterolone is a strong androgen with only a weak level of anabolic activity. It is not regarded as a strong muscle builder. However, it is also known to display an extremely high affinity for plasma-binding proteins such as SHBG (sex hormone-binding globulin). Thus mesterolone may work to potentate the activity of other steroids, by displacing a higher percentage into a free, unbound state. Among athletes, mesterolone is primarily used to increase androgen levels when dieting or preparing for a contest, and as an anti-estrogen due to its intrinsic ability to antagonize the aromatase enzyme.

When used for physique- or performance-enhancing purposes, the usual dosage among male athletes is between 50 mg and 150 mg of mesterolone per day, or two to six 25 mg tablets. The drug is typically taken in cycles of six to 12 weeks in length, which is usually a sufficient period of time to notice the benefits of drug therapy. This agent is not recommended for women for physique- or performance-enhancing purposes, due to its strong androgenic nature and tendency to produce virilizing side effects. However, some women do favor the drug, and find a single 25 mg tablet enough to efficiently shift the hormone balance in the body, greatly impacting the look of definition to the physique. Intake is usually limited to no longer than four or five weeks in such situations, to minimize the chance of developing lasting virilizing side effects.
