The 1st week, I've noticed a modest increase in my ability to focus. My energy levels have been good in the morning with a slight dip in the early afternoon. This is most likely due to the caffeine.

I’m still getting used to it. I had to start at a lower dosage because of the amount of caffeine in it. Building up to the recommended dosage. So far so good

Does what it says it will do

Works well for focusing on tasks
