Hi Doron! I love the lions mane spagyric. It has helped me come off prescribed stimulants for ADHD, as it helps me tremendously with a clear head and long lasting focus. I enjoy the spagyric because I can take it with me to work & school, and easily put a few drops under my tongue for quite strong effects when I need it. I do find that my cognitive ability is sharper and that I can recall memories more quickly when I am working with this mushroom!
