Review: Sustainable energy without any negative effects!! - I’m very pleased! The slow release of the caffeine gives you sustained energy without the jitters or nervousness. They’re easy to use, and a perfect quantity for an excellent price! I use many of NOW’s supplements and I’m more than pleased each time!! Excellent quality when compared to similar products. Nice thing too is, if you have that one day you need this,.. you can take 1 in the morning and take the second one later in the day. You’ll just feel “not tired”. You don’t feel “wired”! You just feel awake and ready!! I love these. I’ve used them every day for 3 months now and the effect hasn’t changed at all. Also,.. gives me a nice boost on the days I take them before the gym! Again,.. not “wired”,… just ready!!!
Review: Good supplement - I've only been taking these for a week, but so far I love them. I usually only take 1 in the morning, and I can feel the extra energy. It gives me good energy and focus with no jitters.
