Anabolic steroids are manmade medications related to testosterone (male sex hormone). Doctors use anabolic steroids to treat hormone problems in men, delayed puberty, and muscle loss from some diseases.

Bodybuilders and athletes may misuse anabolic steroids to build muscles and improve athletic performance, often taking doses much higher than would be prescribed for a medical condition. Using them this way is not legal—or safe, and can have long term consequences.

Anabolic steroids are only one type of steroid. Other types of steroids include cortisol, estrogen, and progesterone. These are different chemicals and do not have the same effects.

How Anabolic Steroids Are Misused

When people take steroids without a doctor’s prescription or in ways other than as prescribed, they are abusing steroids.

Some people who abuse steroids take pills; others use needles to inject steroids into their muscles.

What happens to your brain when you misuse anabolic steroids?

Anabolic steroids affect a part of the brain called the limbic system, which controls mood. Long-term steroid abuse can lead to aggressive behavior and extreme mood swings. This is sometimes referred to as “roid rage.”

Steroids can also lead to feeling paranoid (like someone or something is out to get you), jealousy, delusions (belief in something that is not true), and feeling invincible (like nothing can hurt you).

What happens to your body when you misuse anabolic steroids?

Abuse of anabolic steroids has been linked with serious health problems. They include:

  • high blood pressure
  • changes in blood cholesterol (increases in “bad” cholesterol or LDL, decreases in “good” cholesterol or HDL)
  • enlarged heart
  • heart attack or stroke (even in young people)
  • liver disease, including cancer
  • kidney problems or failure
  • severe acne


  • breast growth and shrinking of testicles
  • low sperm count/infertility (unable to have children)
  • increased risk for prostate cancer


  • voice deepening
  • growth of facial hair
  • male-pattern baldness
  • changes in or end of menstrual cycle/getting your period
  • enlargement of clitoris

In addition, if teens abuse anabolic steroids, they may never achieve their full height because anabolic steroids can stop growth in the middle of puberty.

Can you overdose or die if you misuse anabolic steroids?

Yes. Although it is rare, there are a few ways steroid use can cause death.

  • Heart attacks and strokes. Steroid misuse can lead to a condition called atherosclerosis, in which fat builds up inside arteries and makes it hard for blood to flow. When blood flow to the heart is blocked, a heart attack can occur. If blood flow to the brain is blocked, a stroke can occur.
  • HIV. People who inject anabolic steroids using needles may share dirty drug injection equipment that can spread serious viral infections such as HIV/AIDS or hepatitis (a liver disease).
  • Depression. Steroid misuse can lead to depression, especially during withdrawal. In rare cases this can contribute to destructive behaviors, including suicide. 
  • Cancer. There is some scientific evidence that repeated use of anabolic steroids can contribute to the development of liver and prostate cancer. 

Are anabolic steroids addictive?

They can be. Addiction to steroids is different compared to other drugs of misuse, because users don’t become high when using; however, they can experience withdrawal symptoms. People who do become addicted keep using steroids despite bad effects on their bodies and lives. Also, people who misuse steroids typically spend a large amount of time and money obtaining the drugs, another sign they could be addicted.

When they stop using steroids, people can experience uncomfortable symptoms such as feeling depressed, mood swings, feeling tired or restless, loss of appetite, being unable to sleep (insomnia), and the desire to take more steroids. Depression can be very dangerous, because it sometimes leads people to think of or attempt suicide (killing themselves). If not treated, some symptoms of depression that are linked with anabolic steroid withdrawal have lasted for a year or more after the person stops taking the drugs.

What should I do if someone I know needs help?
