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.

Anabolic steroids are prescription only drugs. Possessing them for personal use is not illegal. But, counterfeit steroids that are quite readily available over the internet are Class C drugs. The maximum sentence for possession for supplying anabolic steroids is 14 years in prison and/or an unlimited fine. Drug testing has outlawed the use of steroids in sport.
