I’ve been taking Catalyst XT for a few months now and I love it! It doesn’t make me feel jittery at all. It gives me the energy I need throughout the day without the crash. I started just taking one pill a day and now I’m finally starting to take two. Its the best thing I’ve tried since the Pure Bee Pollen! I feel like I should be a sales rep for this product because I’ve recommended it to so many people and quite a few have started taking it now as well.
