A wikipedia article on the legal status of anabolic steroids.

"The legal status of anabolic steroids varies from country to country: some have stricter controls on their use or prescription than others though in many countries they are not illegal. In the U.S., anabolic steroids are currently listed as Schedule III controlled substances under the Controlled Substances Act, which makes simple possession of such substances without a prescription a federal crime punishable by up to one year in prison for the first offense. Unlawful distribution or possession with intent to distribute anabolic steroids as a first offense is punished by up to ten years in prison.[119] In Canada, anabolic steroids and their derivatives are part of the Controlled drugs and substances act and are Schedule IV substances, meaning that it is illegal to obtain or sell them without a prescription; however, possession is not punishable, a consequence reserved for schedule I, II, or III substances. Those guilty of buying or selling anabolic steroids in Canada can be imprisoned for up to 18 months.[120] Import and export also carry similar penalties. In Canada, researchers have concluded that steroid use among student athletes is extremely widespread. A study conducted in 1993 by the Canadian Centre for Drug-Free Sport found that nearly 83,000 Canadians between the ages of 11 and 18 use steroids.[121] Anabolic steroids are also illegal without prescription in Australia,[122] Argentina, Brazil and Portugal,[123] and are listed as Class C Controlled Drugs in the United Kingdom. Anabolic steroids are readily available without a prescription in some countries such as Mexico and Thailand."
