In its innovative survey, FDA has analyzed 17 dietary supplements sold online for treating erectile dysfunction in men and found that these drugs contained contain potentially harmful and undeclared ingredients.
They have immediately sent warning letters to the firms who market these products saying that the drugs they market are misleading, illegal and that their chemicals may have side effects to certain people, which their labeling doesn’t state.

The potentially dangerous products are Zimaxx, Libidus, Neophase, Nasutra, Vigor-25, Actra-Rx and 4EVERON.
Some of them, like Libidus and 4 EVERON, have already been stopped from entering The States.

The problem with these products is that they contain undeclared chemicals that may interact with nitrates found in many prescription drugs and lower blood pressure to dangerous levels. It is men who use these drugs that suffer from erectile dysfunction the most. Those are people who suffer from diabetes, high blood pressure, high cholesterol, and heart disease.
FDA warns the public about these potentially dangerous products and recommends seeking professional help before purchasing any online products.
