Proviron (Mesterolone) 10mg – 100 tablets/bottle
Alpha North Labs Proviron is an androgenic/anabolic steroid with a particularly high affinity for SHBG (sex hormone binding globulin). SHBG is a protein that acts by binding to sex hormones and preventing them from interacting within the body at places like the AR (androgen receptor). Because of its high affinity with SHBG, Proviron’ main use is to competitively bind with SHBG, freeing up more of the endogenous hormone to be active within the body. In effect, proviron acts as a ‘magnifier’ of the anabolic effects of steroid hormones. It also exhibits anti-aromatase activity, hence helping to prevent the conversion of certain steroids into estrogen. As a result, the intake of Proviron while on a cycle of steroids, results in a ‘hardening’ of skeletal muscle – a look which is very popular amongst steroid users. One side effect of Proviron is the increased frequency and severity of erections, particularly during sleep/upon waking. Although Proviron is an orally administered steroid, and is alkylated to survive the first pass through the liver, it is considered to be almost completely non-toxic to the liver.
Proviron is used to replace testosterone in men with hypogonadism. Male hypogonadism is a condition when the body does not produce enough testosterone.
Testosterone is a natural male hormone, known as an androgen, which controls normal sexual development in men.
Testosterone is essential for the development and maintenance of the male reproductive organs as well as other male characteristics, such as hair growth, deep voice, sexual drive, muscle mass and body fat distribution.
Proviron is for use in male patients only.
Tell your doctor or pharmacist if you notice any of the following and they worry you:
- fluid retention
- breast enlargement
- increased sexual drive
- psychiatric disturbances such as depression, aggression, increased or decreased energy levels, elation or irritability
- excessive hairiness
- premature puberty
- stunted growth
In the medical world for the treatment of insufficient androgenicity, a single tablet of 25mg taken three times per day (for a total of 75mg per day) is used at the onset of treatment, followed by a reduction in dose later on to maintenance levels of a single 25mg tablet per day. In the treatment of male infertility, the same dosages are normally used, though other fertility-boosting drugs are also included alongside Proviron.
In the case of bodybuilders and athletes, Proviron is normally used between 50 – 150mg per day to either control Estrogen levels, reduce water retention (caused by estrogen), or to increase fertility following the conclusion of a cycle.
Although Proviron is not approved for use in females, some females in the athletic and bodybuilding community do elect to use it. In this case, a single Proviron dosage of 25mg per day is enough to alter the look of the physique. This should be done no longer than 4 – 5 weeks in order to avoid virilization effects.
