I was diagnosed with Hepatitis C and cirrosis in 1989. I have been through 3 rounds of interferon with no success. I originally purchased Immunocal for my mother-in-law who has lung cancer. She noticed an improvement in her energy level right away. I decided to try it for myself and have noticed more energy and an overall sense of wellness. I am anxious for my next doctors visit to see how my blood work-up looks. I have only been using the product for about 3 weeks. My wife has no significant health problems but is taking Immunocal as a preventive measure and is already a believer after nearly 2 weeks. She was a skeptic at first. So now my whole household endorses the product. I look forward to better health and better living! My back pain and pain in my side (from cirrosis and Hepatitis-C) has improved along with more energy and desire to get out and do things.
