Vivaxlstar rating 5StevenApril 13, 2007I got this product as a free sample with another product I ordered. I took it before a job interview this afternoon - it made me more cheerful and gave me more energy than strong coffee or any of the energy drinks on the market which I consider a waste of money. I felt fantastic, energetic and motivated. It's very rare that I am impressed with a product that is "supposed" to give you energy or lift your mood. I have never experienced any product like this in my life.
