That's all I can say. This product is great. I have given this product to several friends and simply told them to try it and tell me if it worked. Every one of us have nothing but good things to say. The product just work!! I use it immediately when I think I might be getting a cold and within a day or two I am fine. My friends have tried it days after a major cold has infected them and they immediately see a difference the next day in how they feel.
