I have been using Longevinex for 2 years. I can feel the changes taking place. I started use after it was recommended by a friend of 30 years who says Longevinex saves his heart and veins particularly. His story is compelling. The change is slow, as expected, as my problems did occur over a long period of time. But in only 2 years many improvements to my health are obvious. I’m 82, and my doctor is impressed with the improvement in my health issues. The price is reasonable, ordering is easy, and delivery is timely.
