The FDA tells us that Vigor-25, a product marketed as a natural dietary supplement to enhance male sexual performance, should not be purchased or used because it contains sildenafil, the active ingredient in the prescription drug Viagra.

The FDA is investigating the reported death of a 26-year old man, possibly associated with the use of Vigor-25.


Sildenafil may interact with prescription drugs known as nitrates, including nitroglycerin, and can dangerously lower blood pressure.

The bottom line?

Vigor-25 is distributed by Piston Corp and sold on Internet sites and possibly in some retail stores.

The FDA advises consumers who have experienced any negative side effects from sexual enhancement products to stop using them. Then, consult a healthcare professional and safely discard the product.

The FDA urges healthcare professionals and consumers to report adverse events or side effects from Vigor-25 to the FDA’s MedWatch Adverse Event Reporting program.
