NO2 Black found useful for blood pressure and prevention of muscle pain

Posted by Reviewer3116060 on May 02, 2011

This product helps to prevent and even alleviate the muscle pain and stiffness that used to frequently accompany my exercise activities. My wife also has found it a useful component in her efforts to manage high blood pressure with minimal reliance on conventional pharmaceuticals -- alongside diet, exercise, and hot baths.
