Proviron – Mesterolone
Proviron is the trade name and commonly used term for the active ingredient, and it is considered, to all intents and purposes, 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 is therefore not useful for building muscle mass because an enzyme metabolizes it, rendering it inactive—it has the ability to release free testosterone, thereby optimizing (and sometimes enhancing) the utilization of other anabolic active ingredients such as testosterone and its derivatives; this occurs because Proviron binds very easily to SHBG
Essentially, Proviron is a derivative of DHT , so it works very well for definition, giving a more aesthetically pleasing and 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 boosting libido and helping to tone the body and achieve a leaner appearance, Mesterolone is primarily used for its aforementioned ability to release. free testosterone , thereby enhancing the effectiveness of other products used in combination with Proviron. In fact, for the same amount of testosterone—mg for mg—it will be more effective when taken with Proviron, and the same applies to all other testosterone derivatives.
This means that Proviron can be used both in bulking cycles—to enhance the effects of other steroids being used and to prevent the accumulation of excess water—and in cutting cycles, thanks to its cosmetic and anti-aromatization
