Provironum (Mesterolone or Proviron) by Schering. Mesterolone is a hormone that has moderate androgenic activity and significantly enhances erectile function. Proviron is often used in bodybuilding during a cycle of anabolic steroids for various purposes.

Proviron is a weak aromatase inhibitor, i.e. it slightly interferes with the conversion of steroids to estrogens in the body. According to numerous reports from athletes, in practice Proviron does not prevent gynecomastia, water accumulation, female fat deposition, and other estrogen side effects.

Proviron has practically no effect on the body’s own testosterone production (it can be suppressed in high doses), but it does help to increase free testosterone concentration in blood, since it blocks the activity of sex hormone-binding globulin. These properties make Proviron attractive during a cycle. This drug is available for sale in our online shop in Australia at a great price.

Effects of Mesterolone

Proviron has a wide range of effects. Many athletes do not consider this drug seriously, which makes them confident that it is safe to use. But in fact, the active ingredient is essential for keeping athletes healthy.

Proviron is a powerful anti-estrogen that reduces the overall aromatic effect of steroids. This prevents the accumulation of excess fluid in the body. The main advantage of the product over all analogues is that it has no inverse effect on the athlete’s organism once the product has been used.

Proviron is in high demand in bodybuilding. It can be used to give muscles extra hardness. This feature of the substance is especially relevant during the preparation of athletes for competitions. The product is also actively used by women who are professional bodybuilders.

A Proviron cycle

The usual daily dosage for men is 50 mg per day divided into two equal doses, preferably after meals. A dosage of up to 100 mg of Proviron per day is considered acceptable. Higher doses of Proviron may have the opposite effect to that expected. In the case of prolonged erections, which are often quite painful and uncomfortable, the dosage of the drug should be reduced or stopped altogether.

Given that the drug increases libido and improves potency in men, its use is justified in a cycle of libido-lowering drugs (e.g., the use of nandrolone or trenbolone).

In addition, Proviron in bodybuilding is often used in pre-competition training to increase muscle hardness and give it relief. It is a favourite product of western movie actors to give the appearance of muscularity to those who are afraid to use heavier steroid “artillery”. It is also used by female bodybuilders to build muscle mass, but their doses should not exceed 25 mg per day for no more than four weeks to avoid the phenomenon of masculinisation. Professional bodybuilders do not adhere to these standards, though.

Side effects of Mesterolone

The drug is considered one of the safest in the steroid range. Its side effects on males are negligible or non-existent. But it can cause a lot of problems in women. Its use may lead to increased hair growth in different parts of the body, a rougher voice, and a more masculine appearance. Blood cholesterol levels could also increase, blood pressure could rise, and rashes could appear on the body. Hair on the head may start to fall out. In women, the drug may also cause infertility.
