I was very positive startled at how quickly I noticed the effect of your Lion's Mane product. Within two days I felt a very noticeable improvement in mental clarity. I had read about Lion's Mane as a product to effect such a result, but I was very skeptical based on "meh" type experiences I have had in the past with a wide variety of herbal and "improves mental acuity" products. This really and genuinely works for me.
