Provibol – a hormonal drug whose active ingredient is Mesterolone, is able to strengthen the functions of erection and cause a slight androgenic activity. Bodybuilders use Provibol during the course of anabolic steroids – it helps to solve a wide variety of tasks. Provibol does not give steroids in the body to convert into estrogens, being an inhibitor of aromatase. Provibol does not allow the development of gynecomastia, does not allow edema, fat deposits and estrogen side effects. Absolutely does not interfere with the body to produce its own testosterone (in increased doses can inhibit the production), but on the contrary, it helps to increase the concentration of free testosterone in the blood, blocking the activity of the sex hormone binding globulin. Very often, the drug Provibol is used during post-course therapy, although the feasibility of this action is questionable, since this drug has absolutely no ability to restore the secretion of endogenous testosterone.
Effects of admission
Increase libido (sexual desire) in men, improve potency.
Increase of firmness and relief of muscles. This property causes frequent use of Proviron in bodybuilding. It is used even by women, however, in much smaller dosages (however, professional bodybuilders do not concern these “stupidities”).
Improvement of the quantity and quality of spermatozoa
Compensation for weak production of androgens.
Stimulation of the development of secondary sexual characteristics and male genital organs.
How to Take Proviron
The Proviron course is not used solo. Usually, the steroid is used in mixed courses with other AAS as an anti-estrogen. The choice in such moments, as a rule, is between Tamoxifen and Proviron. The first agent, although it blocks the activity of estrogen receptors, does not interfere with their formation. Tamoxifen, given its ability to stimulate the production of its own testosterone, is able to influence the pituitary gland, as well as reduce the anabolic activity of the AACs used in parallel. That is why it is adopted only during the period of PCT. Proviron, on the contrary, is the prerogative of a course of steroids.
As for how to take Proviron, the medication is usually used from the second week of the course at a dosage of 50 milligrams, in conjunction with aromatase inhibitors. But in 2-3 weeks after the completion of the course Tamoxifen is connected in a dosage of up to 20 milligrams daily.
Possible side effects from Proviron include baldness and prostatic hypertrophy, caused by the chemical nature of the active substance and its similarity with dihydrotestosterone. During the course of the steroid, periodic examinations of the state of the prostate gland are recommended. Possible, although extremely rare, are benign and malignant liver tumors. Also, if the recommended dosages and regimens are exceeded, negative reactions such as intra-abdominal bleeding, increased liver size and pain in the upper abdomen are not ruled out. There is some erroneous information that Proviron weakens the action of anabolic steroids, because it has an effect on them on the same receptors. The refutation is obvious: first, the high affinity of the drug with the binding proteins on the contrary contributes to the increase in the concentration of free AS, and secondly, this antiestrogen is very rapidly destroyed in the muscles to inactive metabolites.
