Product Name:PROVIRON
: Dragon Pharma
Substance: Mesterolone (Proviron)
Package: 25mg (100 pills)


Proviron is an orally administered androgenic called Mesterolone (1-methyl dihydrotestosterone) from Dragon Pharma. Mesterolone is a strong androgen and shows a weak level of anabolic activity. This is because, like dihydrotestosterone, Mesterolone is rapidly reduced in muscle tissue to inactive diol metabolites, where the concentration of the enzyme 3-hydroxysteroid dehydrogenase is quite high.

Effects of Proviron

You should not take seriously the belief that the weak anabolic nature of this compound causes blockage of androgen receptors in muscle tissues, thereby reducing the benefits of other steroids that are more powerful for muscle building. In fact, due to its extremely high affinity for plasma proteins, such as SHBG, Mesterolone can actually affect the activity of other steroids converting a higher percentage of them to a free unbound form. In athletes, Mesterolone is mainly used to increase androgen levels during diets or preparation for competitions and as an anti-estrogen due to its ability to counteract aromatase enzymes. Mesterolone can be effective in increasing the ratio of androgens to estrogens, leading to increased muscle hardness and density, maintaining libido and a general sense of well-being, and increasing fat burning tendencies. It is also widely used to prevent gynecomastia, while other aromatized steroids are often used in combination with 10-20mg of Nolvadex per day.

Instructions for use

Many bodybuilders prefer to use Mesterolone during drying periods or in preparation for a competition, when low estrogen and high androgen levels are especially valued. The usual dosage for male athletes is 50-150mg of Mesterolone per day, or 2-6 tablets of 25mg. The drug is usually taken in cycles of 6-12 weeks, which is enough to see results.

Side effects

Mesterolone does not aromatize in the body and does not exhibit noticeable estrogenic activity. Anti-estrogen use is not necessary when using this steroid, as the drug does not cause gynecomastia, water retention, or other estrogen-related side effects. Mesterolone acts as an anti-aromatase in the body, preventing or delaying the conversion of steroids to estrogens. Mesterolone is classified as an androgenic steroid. Androgenic side effects with this substance are quite common and can include oily skin, blackheads, and body or facial hair growth. Anabolic-androgenic steroids can also exacerbate male pattern baldness. Women should be aware of the potential virilization effects of anabolic-androgenic steroids. These can include deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and enlarged clitoris. Mesterolone is not a 17-alpha alkaline compound and produces no known hepatotoxic effects so hepatic toxicity is unlikely. Mesterolone has very little suppressive effect on gonadotropins and testosterone. Studies show that when administered at moderate doses (150mg or less per day), there is no significant suppression of testosterone levels. In studies, at higher doses (300mg per day or higher), the agent is able to strongly suppress testosterone. In the Proviron pills section you can see products from other manufacturers.
