I was so hesitant to try. But I was absolutely desperate for help and decided to give it 4 months. I was headed straight for death’s door, and Immunocal has turned me around and is driving me back to health. I did get die-off and healing reactions which weren’t pleasant, plus fevers. But i stuck with it and it is helping me heal from mystery illnesses I’ve had for 6 years where there were times I truly wanted to die. I love it and will take it forever.
