Mesterolone (Chemical Formula is C₂₀H₃₂O₂), also known as Proviron, is one kind of synthetic androgen and anabolic steroid medication commonly used to treat low testosterone levels in men. In simpler terms, this drug has been used to cure male infertility. Developed in the 1960s, Schering, a German pharmaceutical company, first medically introduced Mesterolone in 1967. Schering has started marketing Mesterolone to treat testosterone deficiencies, infertility, and male sexual dysfunction. Over time, its unique properties and diverse applications have made it a subject of interest in the medical, bodybuilding, and sports communities.
This anabolic steroid has strong androgenic propriety. Provimed is used to treat sexual dysfunction, libido, a higher level of sperm, or impotence caused by low testosterone amount. It is an oral testosterone replacement that has a strong androgenic effect but does not affect muscle growth.
One of its primary uses is treating hypogonadism, a condition characterized by low testosterone levels in men. Mesterolone acts as an androgen replacement therapy, helping restore hormonal balance. It also finds utility in addressing fertility issues caused by low sperm count or poor sperm quality. Additionally, mesterolone is sometimes prescribed to counteract the side effects of other anabolic steroids, such as reduced libido and mood disorders.
Due to its unique properties, Mesterolone has garnered attention among bodybuilders and fitness enthusiasts. It does not possess significant anabolic effects but exhibits strong androgenic properties. As a result, bodybuilders often use mesterolone to enhance muscle hardness and definition. It works by binding to the sex hormone-binding globulin (SHBG), freeing up more testosterone, which can exert greater anabolic effects in the body. Additionally, mesterolone's anti-estrogenic activity helps mitigate estrogen-related side effects, such as water retention and gynecomastia, commonly associated with anabolic steroid use.
Some competitive bodybuilders at pre-contest preparation believe adding Mesterolone will improve muscle density and hardness. It's because of the ability to decrease water retention and reduce circulating estrogen in the body.
Mesterolone has found its way into sports due to its potential performance-enhancing effects. Athletes from various disciplines have explored mesterolone's benefits, especially in sports that require strength, endurance, and power. Due to its androgenic nature, mesterolone can boost aggression and assertiveness, which may translate into increased motivation and competitiveness. However, it's important to note that mesterolone is classified as a prohibited substance by most sporting organizations, including the World Anti-Doping Agency (WADA). Athletes testing positive for mesterolone may face severe penalties, including disqualification and suspension.
Other possible side effects:
Steroid cycles for bodybuilders and athletes typically involve a dosage range of 25-100 mg daily. It is advisable to start with a lower dose and gradually increase it to gauge individual tolerance. The duration of mesterolone usage in a cycle can vary but is typically within the 8-12 weeks range.
Mesterolone is commonly used with other steroids to enhance muscle hardness and definition while minimizing estrogen-related side effects.
One tablet in combination with 10-20 mg of Tamoxifen is very efficient for muscle hardening. It's creating the environment for burning off the extra body fat, especially for women's areas, like the hips and thighs.
