I took the 72 hour GungHo challenge to see if it could help when I was tired without the jitters and crashes that coffee and sodas can cause. From my personal experience I didn't feel any jitters, I wasn't a huge fan of the flavor, but I don't like many flavors. It was a citrus'y kind of flavor which wasn't overtly strong, but just not my cup of tea. However, I don't really care what it tastes like when you shoot it and it gives you energy.
For the time I used the GungHo I did seem to have a boost in energy, but it was a steady energy not a up & down kind of energy. I can't attest as to if I felt like it helped me focus, but I guess anything that keeps me from falling asleep helps.
