The potential side effects of methadrostenol include pimples, hair loss, potentially fatal tumors on the liver, clogged arteries, breast growth in men, beard growth in women, changes in mood and behavior and permanent visuospatial impairment, according to WebMD. Methadrostenol, otherwise known as dianabol or D-bol, is an anabolic steroid, and its side effects are similar to other anabolic steroids.
According to WebMD, the side effects of anabolic steroids result from an overabundance of testosterone in every organ in the body. Some of the side effects are reversible and improve over time once a person stops abusing steroids, but other effects are permanent. In males, anabolic steroids can cause the testicles to shrink in addition to a reduced sperm count and hair loss. Females can experience a lower voice, excessive body hair and shrunken breasts. Teenagers who use anabolic steroids before their bodies finish growing are at risk of stunted growth. Steroids can affect the stability of a user's mood and can produce a homicidal rage in which normally stable people become murderously enraged. Less severely, steroids can cause mild depression and irritability. Over time, the abuser may experience delusions, mania and aggressive behavior.
In a 2012 study reported by Medical News Today, Dr. Harrison Pope, MD, found that the use of anabolic steroids negatively affects the user's visuospatial recall. This symptom is similar to what is seen in dementia patients who can easily become lost or disoriented.
