Start here

Cohort One

You've got the box. Here's the short version.

A ninety-second video from me is going up here shortly. Until then, everything you need is on the card in the box, and this page says the same thing.

Start tomorrow, not today

Day one should be a normal day, so you've got something to compare against.

One row per stick

Take a Focus before the first demanding thing you do. Fill in the row on the pad, then score your concentration out of ten right before you take it, and again an hour later.

Fifteen sticks, ten days. Ten Focus, five Perform. The Perform ones are your call.

Fill in every column

Time tells us whether time of day changes anything.

What you mixed it in tests our claim that this works in anything. We'd like to know where that stops being true.

What you took it before is how we find out which moment it actually suits, rather than guessing.

Before and after are the experiment.

Then the notes. Please don't skip them.

The numbers tell us whether something changed. Only your words tell us what it was actually like. If it tasted odd in something, dissolved badly, hit harder one day than another, or did nothing at all, write it down.

Missed a day?

Leave the row blank and carry on. Missed days go into the published results too.

Results are due 1 October. I'll email you the form on day eight, so there's nothing to remember.

Anything at all, reply to any email from me and it comes straight through.

Thank you again for doing this.
