茶氨酸補充劑

My second month on these and the focus is still solid — no jittery crash like I'd get with my old coffee routine. The slow-tolerance thing is real for me, I haven't needed to up the dose once.

Three weeks in and I still get the same clean buzz from one capsule that I did on day one, no jitters or crash. The slow tolerance build is the real deal for someone like me who was burning through coffee by noon.

I was skeptical about swapping out my morning coffee, but the clean energy from this lasts a solid six hours without the jitters or the afternoon crash. The slow tolerance buildup is real — my usual caffeine dose stopped working after a week, but this still hits the same after a month of daily use.
