Provibol – a hormonal drug, the active ingredient of which 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 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 expediency of this action is questionable, since this drug has absolutely no ability to restore the secretion of endogenous testosterone.
For men, the daily dosage is 50 mg, divided into two doses. A dose of 100 mg is considered acceptable. If you exceed the dose of the drug, the effects may be opposite to the expected. If any malaise occurs during the use of the drug, it will be necessary to consult a physician.
This drug in moderate dosages does not have a toxic effect on the liver, which makes its use harmless for several weeks. Also, it does not suppress the axis of the hypothalamus – the pituitary gland – the testicles. The chemical nature of the drug has many similarities to dihydrotestosterone, which can cause prostate hypertrophy and hair loss in men in that part of the head that is more rich in hair. To prevent side effects it is necessary to conduct examinations of the prostate gland from time to time.
