Caffeine

The capsule size is perfect for quick swallowing with water, and I've noticed the focus boost kicks in reliably about 20 minutes after taking it. It's been a steady part of my afternoon routine for a few weeks now, and the consistent dose means no surprise jitters later.

Three weeks in and the precision dosing is what sold me—every capsule hits the same way, no surprise jitters or crashes. I split the dose by opening one and taking half, which is easy since they're plain capsules. Focus stays sharp through the afternoon slump without me reaching for a second cup.

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.
