There is no doubt that Anavar is one of the most effective fat burners, available in the market. It increases the rate of metabolism in the body that produces body heat. And this body heat helps to burn excessive fat and converts those fats into body energy. Despite the positive impacts, ignoring the side effects will not be a very good idea. With higher dosage of this steroid, normal Testosterone production in the body may get hampered. This is why when taken with higher dosage, drugs like Clomid or Nolvadex should be applied at the same time.
