Mesterolone is a hormonal androgenic drug, better known under the trademark Proviron. Release form – a package of 20 tablets, 25 mg / tab. Proviron is often used in on a course in conjunction with various anabolic steroids. Mesterolone is a rather weak aromatase inhibitor, but still interferes with estrogenic manifestations. Long-term practice shows that he is practically unable to suppress gynecomastia, the formation of female body fat deposits, and other effects of aromatization.
Effects from taking Proviron
- Increased libido (sexual attraction) in men, improved potency.
- Increase of hardness and relief of muscles. This property causes frequent use of Proviron in bodybuilding. It is even used by women, albeit in much smaller dosages (however, professional “bodybuilders” do not concern these “nonsenses”).
- Improving the quantity and quality of sperm
- Compensation of weak androgen production.
- Stimulation of the development of secondary sexual characteristics and male genital organs.
- Anabolic properties.
How to take Proviron
The course Proviron is not used solo. Usually, the steroid is used on mixed courses with other AAS as an anti-estrogen. The choice at such moments, as a rule, stands between Tamoxifen and Proviron. The first remedy, although it blocks the activity of estrogen receptors, does not prevent their formation. Tamoxifen, given its ability to stimulate the production of its own testosterone, is able to affect the pituitary gland, as well as reduce the anabolic activity of parallel used AAS. That is why it is accepted only during the PCT period. Proviron, by contrast, is the prerogative of a steroid course.
As for how to take Proviron, usually the tool is used from the second week of the course in a dosage of 50 milligrams, together with aromatase inhibitors. But after 2-3 weeks at the end of the course, Tamoxifen is connected at a dosage of up to 20 milligrams daily.
Possible such side effects from Proviron as baldness and prostatic hypertrophy, caused by the chemical nature of the active substance and its similarity to dihydrotestosterone. During the course of the steroid is to conduct periodic surveys of the prostate gland. Possible, although extremely rare, benign and malignant liver tumors. Also, if the dosages and regimens are exceeded, such negative reactions as intra-abdominal bleeding, an increase in the size of the liver and pain in the upper abdomen are not excluded. There are some erroneous reports that Proviron weakens the action of anabolic steroids, since it has the same effect on the same receptors. Denial of the obvious: firstly, the high affinity of the drug with binding proteins, on the contrary, increases the concentration of free AU, and secondly, this anti-estrogen is very quickly destroyed in the muscles to inactive metabolites.
