After 2 weeks of using this product, I have noticed a slight increase in energy. Not as much as I thought but still an increase. I have also noticed that my joints are hurting less and believe it is due to taking cordyseps plus. I plan on buying more soon and hope that I am feeling even more energetic after using cordyseps plus for a longer period of time.
