I think our bodies are so unique in that what works for one person will not necessarily work for someone else. I tried a product (Adaptocrine) and I thought I was coming out of my skin. My heart pounded, I perspired, and felt very anxious. I finally realized that I can't take Ginseng (in any form), and the product had lots of Ginseng (different forms).
So far, the Adrenal Builder product is the only Wilson product I am using. I do not intend to purchase the other products and am still not sure whether to attribute the improvement to his product or the other things I am doing. (e.g.,Anti-fungals, Adaptogens, B-Compes, Ester-C, etc).
