Anabolic steroids are manufactured medicines that copy the effects of male hormones, such as testosterone. They have limited medical uses and are not the same as corticosteroids, a different type of steroid medicine that's more commonly prescribed.
Anabolic steroids are class C medicines, which can only be issued by pharmacists with a prescription.
It's legal to have anabolic steroids for personal use. They can also be imported or exported, as long as this is carried out in person. This means they can't be posted or delivered by a courier or freight service.
However, it's illegal to possess, import or export anabolic steroids if it's believed you're supplying or selling them. This includes giving them to friends. The penalty is an unlimited fine, or even a prison sentence of up to 14 years.

Anabolic steroids can be used to enhance performance and increase muscle mass. Some people take them regularly to improve their physical performance and build up their bodies. But they can also have many undesirable effects.
People of all ages have been known to misuse these medicines, including adolescent boys who have body dysmorphic disorder. This is a mental health condition where a person spends a lot of time worrying about flaws in their appearance, which are often unnoticeable to others.
