คาเฟอีน

I've been taking one capsule with breakfast and the focus is steady for a good four hours without that jittery crash I used to get from coffee. The precise dosing is exactly what I needed to control my intake without guessing.

The capsule format makes it easy to dial in exactly how much I’m taking, which I appreciate for afternoon focus. Only wish the bottle had a few more pills for the price, but it does what it says.
