I have used the Adaptogen, the Brain Booster, and the Inner Peace versions of this product. I find with all three that I am happier and more carefree. I feel this way with no external stimulus. I also have more interest in my surroundings and better motivation to get the things done that need to be done. I have more interest in people and in life. I definitely felt I have an energy and stamina I haven’t felt in a long time and I am 74 years old. It is important to read the booklet on dosing. Your results will be best if you understand and follow the booklet.
