FDA cautions public to avoid PrimeZen Black 6000 due to hidden ingredients

Consumers shouldn't purchase or use PrimeZen Black 6000, a product promoted and sold for sexual enhancement on various websites and possibly in some retail stores. FDA lab analysis confirms that the product contains sildenafil and tadalafil, undeclared ingredients that may interact with nitrates found in some prescription drugs, such as nitroglycerin, and may lower BP to dangerous levels.
