What is it?
Anabolic steroids are a group of hormones found naturally in our bodies. They are involved in growth, physical development and the function of the reproductive organs.
The drugs are manmade versions of the same or similar hormones. They come as pills or capsules. They are usually taken by mouth, but can be injected. Their medical use is limited to boosting red blood cell numbers in anaemic patients.
Bodybuilders, sports fanatics and athletes use them to increase the rate and amount of muscle growth.
Anabolic steroids aren't the same as the steroids used to treat eczema and asthma - these are corticosteroids.
How does it make you feel?
Taking anabolic steroids, training hard and eating a high protein diet will build your body weight up and increase the size of your muscles. Some people say they feel more aggressive and competitive as well.
Occasionally people get 'roid rage' where they are violent and sexually abusive No-one knows if this is down to the drugs or the people though.
What are the health effects?
