Whenever I have a busy day ahead of me, I know I can always count on this product. Personally, I just need to take one pill for the entire day and I'll have all the energy and focus I need to get throughout my day plus the energy to a workout. What I like most about this product is that I get no jittery effects or my heart racing like previous supplements I've taken in the past. I do eat a good breakfast before I take the pill and I don't take it every single day because I like to give myself a break from it. Overall, great product that comes in clutch for those productive days!
