I waited to weigh-in as a first time user of Birch Boy's Lion's Mane. I wanted to make sure it was not some kind of placebo effect. I am pleased with the fact that my very sensitive system which usually doesn't get along with various medicinal properties had only welcomed "side effects" that did not upset my system in the least, even when taken directly. I enjoyed the pleasant subtle effects. In my case less is more, much more and just right.
