The law in the Uk for your referance is:
Anabolic steroids are Prescription Only drugs under the Medicines Act. They can only be sold by a pharmacist on the presentation of a doctor's prescription. Anabolic steroids are also class C drugs under the Misuse of Drugs Act. It is not an offence to possess anabolic steroids for personal use, unless they are counterfeit. It is an offence to supply them. Therefore police tend to arrest for steroid possession only if they can prove the drugs are counterfeit (and therefore not prescribed by a doctor). A small number of arrests and convictions are made on this basis each year.
