The majority of bodybuilders who have used Proviron have been disappointed. The drug has failed to live up to the hype. Most users have claimed that the drug does not increase muscle mass or strength. In fact, the majority of individuals consider it a waste and unwarranted. Part of the problem may be due to the fact that the real Proviron is not available and perhaps people have been buying fake products. There are a lot of reports of counterfeit or fake Proviron products on the market. Unless the drug is tested in a chemistry laboratory it is impossible to tell what one is buying.
The drug does possess anti-estrogen activity like Nolvadex or Arimidex. Thus, it blocks the breast enlargement and water retention which are common side effects of most anabolic steroids.
Some users do claim that it causes the muscle to bulge and a rip- however, many of these users take so many other anabolic steroids; it is difficult to know which drug is actually responsible for the muscle growth. The drug has predominantly been used during the washout cycle to maintain the testosterone surge. Most knowledgeable athletes have stopped using Proviron and have turned instead to Arimidex or Nolvadex.
