Excellent sustained energy throughout my workout!
This product performs just as described.  For my size, 170 pounds, I can use up to two scoops per the instructions. However, one-and-a-half scoops provides perfect sustained energy throughout my workout, and I'm tolerant of caffeine as a daily coffee drinker.  Green tea extract is the best for long-term energy release.  I'm very happy with the ingredients (short and simple and safe).  The flavor is fine, sweetened naturally with beets and stevia extract.  Only 15 calories per scoop, so it doesn't interfere with my current intermittent fasting routine.  I'm very happy with this product!
