Danazol is a medication that is commonly prescribed to women to prevent various pain in the pelvic region as well as infertility due to endometriosis. Danazol also has some effects in treating various breast conditions and works as a strong androgen which is similar to testosterone.
Danazol can regulate hormones throughout the body and change the way that the ovaries produce their hormones. The medication actually works to halt the production of gonadotrophins and can produce some androgenic effects which are very similar to steroids.

Many male bodybuilders have started to use this as part of an estrogen blocker in their post cycle therapy. During the early 80s when aromatase inhibitors were not available this was the drug of choice as part of a post cycle therapy method.
Danazol can still continue to be used to prevent estrogenic problems in a post cycle therapy. While many bodybuilders do not experience any type of gynecomastia side effects, introducing an estrogen blockers such as danazol can ensure that there is a minimal risk of these side effects from occurring.
Danazol can offer some greater benefits than a traditional estrogen blocker as it helps to boost LH hormones during post cycle therapy. This can ensure a greater level of success in maintaining gains through the training cycle. While there are several options available for estrogen blockers, the properties that danazol has as well as the extensive history in bodybuilding make it theoreticaly a great choice.
As a result of the demand for danazol and its added benefits the expense for this medication is a little more than some of its competitors like clomid or Nolvadex. Each of these solutions will provide you with perfect on cycle or PCT assistance but Danazol has the best proven track record through its experience.
This drug was rarely prescribed for longer than six months due to its risk of ovarian cancer when used for endometriosis in women. Females who suffer from medical problems nowadays have access to several drugs that do not increase their risks for virilization due to androgenic activity.
Athletes who use anabolic steroids have no reason to use this drug these days. There are a lot of steroids available which cause less side effects.
