Viagra is a drug that needs a prescription to buy in Australia, once a prescription is obtained at a local pharmacy. Like most drugs though there a trade in generic substitutes online and in licensed stores. There are numerous sites that sell true Viagra without a prescription, because they are licensed. They list their products as high quality cheap versions of the name brand drug, even going so far as telling the population that there is no difference between their unregulated drugs and the prescription versions.

When buying online from a seller like these a consumer has idea what has been put into the drug and is relying on a seller to ensure their safety.
