How it works

  1. 01

    Tear one stick

    Into water, coffee, tea, anything already in your hand.

  2. 02

    Stir once

    It dissolves clear. No cloud, no grit, no taste.

  3. 03

    Twenty minutes

    100mg caffeine, 200mg L-theanine, then five steady hours.

Tastes like nothing

Dropped one into black coffee and could not tell the difference. That was the whole test.

Steady

The L-theanine is doing something. Steady for about five hours, then it ends quietly.
