Mesterolone, sold under the brand name Proviron among others, is an androgen and anabolic steroid (AAS) medication which is used mainly in the treatment of low testosterone levels. It has also been used to treat male infertility, although this use is controversial.It is taken by mouth.
Mesterolone was first described by 1967 and introduced for medical use by 1967. In addition to its medical use, mesterolone has been used to improve physique and performance, although it is not commonly used for such purposes due to its weak anabolic effects. The drug is a controlled substance in many countries and so non-medical use is generally illicit.
Medical uses
Mesterolone is used in the treatment of androgen deficiency in male hypogonadism, anemia, and to support male fertility among other indications.It has also been used to treat delayed puberty in boys.Because it lacks estrogenic effects, mesterolone may be indicated for treating cases of androgen deficiency in which breast tenderness or gynecomastia is also present.The drug is described as a relatively weak androgen with partial activity and is rarely used for the purpose of androgen replacement therapy, but is still widely used in medicine.
Non-medical uses
Mesterolone has been used for physique- and performance-enhancing purposes by competitive athletes, bodybuilders, and powerlifters.
Proviron Benefits
Proviron is a useful tool in bodybuilding for a variety of reasons. From increased muscle hardness to accelerated sex drive to improved effectiveness of other steroids, let’s dive into these benefits in more detail.
Increased Lean Muscle Mass
Proviron stimulates muscle fibre hypertrophy in the body which encourages the growth of lean muscle mass. This makes it a favored option for individuals looking to build a leaner, stronger body.
Reduced Water Retention
Proviron reduces water retention in the body which allows for drier, harder and more defined muscle mass to be built during a cycle.
Inhibited Aromatization
Aromatization, the conversion of testosterone into estrogen, can be worrisome for men. Proviron effectively inhibits this process, maintaining the balance of hormones within the body.
Improved Effects From Other Steroids
Due to its ability to bind to the Sex Hormone Binding Globulin (SHBG), making other steroids more accessible in the bloodstream, Proviron is able to enhance the effectiveness of other steroids when used in a cycle.
Enhances Testosterone
Proviron is able to boost the body’s free testosterone levels, a crucial aspect for muscle building, energy levels, and overall male vitality.
Helps Erectile Dysfunction (ED)
While not its primary use, Proviron has been noted to assist with issues like Erectile Dysfunction (ED), elevating bodily stages of dihydrotestosterone (DHT) that helps restore sexual function.
Minimizing and Combating the Effects of Estrogen
By inhibiting aromatization, Proviron also serves to minimize and combat the effects of estrogen, often an issue linked to using anabolic steroids. Lesser estrogen equals lesser chances of water retention and undesirable fat gain.
