I still take it every day. I feel like it helps me with mental focus, calmness, motivation and just overall health - but I'm not sure how to quantify all of that. It is possible that it has helped me perform slightly better in my workouts - reduced perception of exertion, less stress from a cardiovascular standpoint in that I don't huff and puff as much on heavy lifts and my rest periods have become shorter. It's subtle and I am going to stick to the habit. At the very least the Theobromine helps pick me up more than just caffeine in my coffee in the morning.
