Proviron (acting in-in the site of the drug) is a relatively strong hormonal drug, which has a rather high androgenic activity. Also, this tool has an unmatched advantage – it has the ability to significantly strengthen the erectile function in men. This drug is often taken by bodybuilders and other athletes to achieve certain results. It is a rather weak aromatase inhibitor, that is, it directly interferes with the conversion of steroids into unwanted estrogens in the human body. But there are also isolated cases of undesirable side effects, about the manifestation of which we’ll talk just below. But these are often isolated cases that have not been proven by practice. Proviron is used just before the start of the competition as a way to achieve excellent stiffness and unsurpassed muscle.
