Provinazol (Proviron) 50 mg Sopharma: description and posology

Provinazol-50 is a drug whose active ingredient is mesterolone. It is used for various purposes by sportsmen, as it has a long list of properties. Provinazol (Proviron) 50 mg Sopharma will be useful both on its own as an anabolic steroid and as part of post cycle therapy. It exhibits androgenic activity.

Positive effects of Provinazol (Proviron) 50 mg Sopharma

The drug is known as a powerful erectile function enhancer (increases libido and potency), but this is far from its only property. It has the following effects:

  • inhibits aromatase (an enzyme that converts testosterone to estrogen), but this property is not very pronounced;
  • it increases the amount of free testosterone in the blood;
  • reduces the activity of globulin, which binds to sex hormones and prevents them from manifesting themselves completely.

In addition, the remedy can be an integral part of combined courses of steroids, as it improves relief and contributes to the acquisition of hardness and stiffness in muscles.

Possible negative effects

Provinazol (Proviron) 50 mg Sopharma causes practically no side effects. It is non-aromatising, has no progestogenic activity, is non-toxic to the liver and does not suppress natural testosterone production.

However, because it is an androgen, it can cause androgenic side effects, including prostate enlargement, baldness and excessive body and facial hair growth. Because of its ability to improve sexual function, a high dose can cause prolonged and painful erection.

Directions for use

Provinazol (Proviron) 50 mg Sopharma is the optimal daily dose for men. It is best to divide it into 2 doses to obtain a more even level of the hormone in the blood throughout the day. The maximum dose is 100 mg per day. This is a safe amount that will not cause side effects.

Since the drug inhibits the action of aromatase, it is used as an additional tool in the course of steroids to control estrogen levels. It is administered in week 2 of the course and is taken at 50 mg per day. After completion of the reception, athletes switch to anti-estrogens with more potent properties, already as a post-cycle therapy.

Before use, it is best to consult a doctor. It will help you to know if you have any contraindications to taking Provinazol.
