Provibol is a hormonal drug whose active ingredient is Mesterolone, which is able to enhance erectile function and cause minor androgenic activity. Bodybuilders use Provibol over the course of anabolic steroids – it helps to solve a wide variety of tasks. Provibol does not allow steroids in the body to turn into estrogen, as an aromatase inhibitor. Provibol does not allow to develop gynecomastia, does not allow edema, fat deposition and estrogen side effects. Absolutely does not prevent the body from producing its own testosterone (in increased doses it can inhibit production), but on the contrary, it helps to increase the concentration of free testosterone in the blood by blocking the activity of sex hormone-binding globulin. Very often, Provibol is used during post-course therapy, although the usefulness of this action is questionable, since this drug has absolutely no ability to restore the secretion of endogenous testosterone.

 How to use Provibol and its dosage during the course

The daily rate for men is a figure equal to 50 mg of the drug, which should be divided into two parts and taken after meals. A dosage of up to 100 mg of Provibol per day is considered acceptable. Higher doses of Provibol can lead to unexpected and unpleasant effects. If, after starting the course of the drug, a prolonged erection began to appear, which in most cases causes pain and discomfort, then you should reduce the dose taken, or stop using it altogether. It must be borne in mind that the drug has a positive effect on libido and improves the quality of potency in men, and that is why its use is justified on the course of drugs that lower libido. In bodybuilding, Provibol is often taken at a time when athletes are preparing to compete, because it is able to increase muscle hardness and gives it relief. Provibol is a favorite drug of Western film actors, which they use to preserve the attractiveness and increase the muscularity of the body, as they are afraid to use heavier steroid “artillery”. This drug is also popular with female bodybuilders, as it gives muscle density. Women, in turn, need to strictly follow the dosage, which should not exceed 25 mg per day for a maximum of four weeks in order not to cause the formation of masculinization.

 Side effects:

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 hypothalamus-pituitary-testes axis. The chemical nature of the drug has many similarities with DHT, which can cause prostatic hypertrophy and baldness in men of that part of the head that is richer in hair. Prophylaxis of the prostate gland is necessary from time to time to prevent side effects.

 Security measures and precautions while taking the drug:

The hormonal substances that make up the Provibol preparation sometimes caused the formation of benign, more rarely, malignant liver tumors. In rare unique cases, the drug can cause bleeding inside the abdominal cavity, formed due to such tumors. If, after taking Provibol, an acute pain occurs in the upper abdomen, the liver is enlarged, or there are signs of bleeding inside the abdominal cavity, then the differential diagnosis should take into account the likelihood of a liver tumor.
