Highly effective.
It is generally uncommon to find a supplement of any sort that works immediately, but this does. Not only did it increase my workout stamina, but has been very helpful with some brain fog that I have been struggling through. I now also take a half serving in the morning before work and find it very helpful for my focus and productivity. I also take a serving before planned workouts.
