Proviron – Mesterolone
Proviron is the trade name commonly used for the active ingredient Mesterolone and is considered an AAS (Anabolic Androgenic Steroid) even though it is not used directly to build muscle mass. Proviron is taken orally and is a truly unique steroid: let's see why.
Chemical composition of Mesterolone – Proviron

Proviron is an anabolic and androgenic steroid and is therefore an agonist of androgen receptors. The androgenic properties of Mesterolone are much more pronounced than its anabolic properties, which is why the product is useful for masculinization (including libido) and for increasing sexual desire. Proviron has ZERO estrogenic effects and is extremely mild on the liver and digestive system, to the point of being completely tolerated. Despite its limited anabolic capabilities, the product is controlled and prohibited in competitive sports.
Medical and athletic use of Proviron
Mesterolone has a very useful property in both medicine and sports: although it has no significant anabolic properties—and therefore is not useful for building muscle mass due to an enzyme that metabolizes it, rendering it inactive—it has the ability to release free testosterone, thereby optimizing (and sometimes enhancing) the utilization of other anabolic compounds such as testosterone and its derivatives; this occurs because Proviron binds very easily to SHBG.
Basically, Proviron is a derivative of DHT, so it works very well for muscle definition, resulting in a more aesthetically pleasing, rock-hard appearance. As mentioned, it does not build muscle mass; therefore, unlike Masteron or Primobolan, it has no anti-catabolic effects.
Proviron has excellent effects on libido and sexual desire, and many people take it for this reason alone. In high doses (too high), it can also increase sperm production.
Where Proviron – Mesterolone excels and shines
In addition to being a highly effective product for libido and for firming and giving a leaner appearance, Mesterolone is mainly used for its aforementioned ability to release free testosterone, effectively enhancing the use of other products that are used in combination with Proviron. In fact, at equal amounts of testosterone, it will be more effective, mg for mg, when taken with Proviron, and this is true for all other testosterone derivatives.
This means that Proviron can be used both in bulking cycles to enhance the effects of other steroids and to prevent excessive water retention, as well as in cutting cycles due to its cosmetic benefits and anti-aromatization properties.
