Something is working really well, and it could be this.
I was offered a free bottle of this product for writing a review, so I'm doing so.  I've been taking it for a couple of weeks.  During those weeks, I've noticed a substantial, very noticeable improvement in my mood, energy levels and physical endurance.  However, I can't say for sure that it was because of this product, because I also started taking two other products at that same time -- Oregon's Wild Harvest Astragalus Reishi and also some L-Tyrosine.  So, it could be this product, or it could be one of the others, or it could be something about the combination of all three.  Either way, I'm very happy about it and I'm going to keep taking this.
