Atilla Fodor, aged 38 years, of Datchet, Slough was sentenced to ten months in prison at Reading Crown Court.
An analysis of his computer during the investigation found he had sold more than 451,000 doses of unlicensed erectile dysfunction medicines which had netted him more than £27,000.
During the raid of his property MHRA investigators found more than 267,000 doses of unlicensed erectile dysfunction medicines stored in a garden shed, with an estimated value of more than £500,000.
MHRA Head of Enforcement, Alastair Jeffrey, said:
Selling unlicensed medicines is illegal and can pose a serious risk to health.
Unlicensed medicines can be dangerous as they may contain impurities, incorrect ingredients, and there is no way of knowing if they are manufactured to acceptable standards of quality and safety.
Criminals involved in the illegal supply of medical products aren’t interested in your health - they are only interested in your money.
MHRA will continue to track down and prosecute those who put the public’s health at risk.
