For optimal results consider Dr. Wilson's Adrenal Fatigue Quartet, the four products which form the adrenal fatigue protocol. Begin on a low dosage and gradually build up. Porcine glandulars are excellent, and I've noticed better results than using bovine or ovine. We have some pretty good bovine products here in NZ, but Dr. Wilson's porcine glandular is what I'll stick with, and after more than 5,000 patients I wouldn't try anything else.
