What to expect, and when

For the first ten minutes of work that decide the next two hours.

01 · The first minute

Clean peppermint, low sweetness, a dry finish. Onset at 60 to 90 seconds.

02 · The first hour

Guarana releases its 22 mg of caffeine more gradually than coffee does. Paraxanthine carries the rest.

03 · Afterwards

Remove at 20 to 30 minutes. Dosed to be usable twice across a working day rather than once.

04 · How often

Maximum 2 in 24 hours.

Safety

What's the feeling?

Focused energy without a cup in your hand. 100 mg of paraxanthine plus 22 mg of caffeine from guarana — 122 mg caffeine-equivalent, every milligram counted. You'll notice a light cooling tingle when it settles — that's the formula activating, and it fades within a minute or two.

When do I use it?

The working middle of the day, 9am–5pm — especially the first ten minutes of a deep-work block, which tend to decide the next two hours.

How's the taste?

Clean peppermint, low sweetness, dry finish. Nothing on your desk, nothing for anyone to notice.

How do I use it?

Under the upper lip, 20–30 minutes, then remove and discard. Do not chew or swallow. Maximum 2 pouches in 24 hours.
