The Food and Drug Administration is warning consumers about a "male sexual stimulant" that is more potent than advertised.To get more news about vigrx oil, you can visit vigrxplus-original.com official website.

During a routine inspection of international mail shipments, the FDA tested samples of Big *****, an over-the-counter supplement advertised as a sexual enhancer. It found at least one surprising ingredient:

"FDA laboratory analysis confirmed that Big ***** contains sildenafil, the active ingredient in Viagra, an FDA-approved prescription drug for erectile dysfunction," the agency said in a release. "This undeclared ingredient can interact with nitrates found in some prescription drugs, such as nitroglycerin, and lower blood pressure to dangerous levels."
Nitrates are often taken by people with diabetes, high blood pressure, high cholesterol and heart disease. Other known side effects of Viagra include headaches, heartburn, flushed skin and a prolonged erection that can lead to penile damage, hearing loss and vision problems.

The dietary supplements industry is worth nearly $32 billion a year. But these products face less scrutiny from the FDA than drugs or food. In fact, manufacturers aren't required to disclose their ingredients unless there's a complaint and an investigation. "These products are typically promoted for sexual enhancement, weight loss and body building, and are often represented as 'all natural,'" the agency warns.

The FDA is unable to test and identify all products marketed as dietary supplements that have potentially harmful hidden ingredients".

In 2015 alone, Viagra was found in more than two dozen herbal supplements, including sexual enhancers such as Hard Wang, Night Man, and Stiff Nights, which was implicated in the death of a Missouri man in 2012."We're not talking about trace amounts of this stuff," Pieter Cohen, an assistant professor of medicine at the Cambridge Health Alliance, told BuzzFeed News at the time. "The FDA doesn't say how much they found, but whenever we've looked at it, these doses are really significant. They can be twice the dosage of Viagra itself."

ED drugs can also end up in other places: Earlier this year, an energy drink sold in Zambia was found to contain sildenafil: A customer reported heavy sweating and a six-hour erection after drinking Power Natural High Energy Drink SX, which was also exported to countries including Uganda, Malawi and Zimbabwe.
