In countries where AAS are controlled substances, there is often a black market in which smuggled, clandestinely manufactured, or even counterfeit drugs are sold to users.
Waddamada AAS ay gacanta ku hayaan maandooriyeyaasha, waxaa inta badan jira suuq madow kaas oo la soo tahriibiyo, qashin lagu sameeyay ama xitaa daawooyinka been abuurka ah ayaa loo iibiyaa dadka isticmaala.
