People who do two hard things a day
“In the mountains I take Cordyceps. On the days between, Lion's Mane.”
Piotr Krzyżowski
Himalayan mountaineer · GOPR mountain rescuer
“I keep the coffee in the kitchen, not the cupboard. It gets used.”
Pascal Brodnicki
Chef, author and television presenter
“Reishi in the evening. That is the one I never skip.”
Cyprian Majcher
Host, Elite Mentality Podcast

The first hard thing
Before anyone else logs on. The block you protect.
and
18:40
The second hard thing
After the day has already taken something. You go anyway.
Solve the day
For the runner up before the streetlights go off. For the founder whose best work happens before anyone else logs on. For the parent doing both.
We make mushrooms for people who solve, not settle — and we put the proof on the label, not in the promise.

Why it costs what it costs
01 — Grown
On wood, not grain
The substrate it evolved on. Grain is cheaper. Grain grows mycelium, not mushroom.
02 — Harvested
The fruiting body only
Cut and dried whole. Species confirmed by DNA — not by eye, not by the supplier's word.
03 — Extracted
Twice, then tested
Hot water for the beta-glucans. Alcohol for the triterpenes. 10:1, then tested before it's packed.
What the certificate says
Every jar carries a lot number. Ask, and we send
the document behind it.

Four fair questions
We're not allowed to tell you, and nobody credible would. What we can tell you is what's in the jar: 100% fruiting body, 10:1, over 30% beta-glucans, on the certificate for your batch. Anyone selling you a timeline is guessing or breaking the law.
Because the £12 jar is usually milled mycelium grown on grain, and the grain goes in the capsule too. Ours is the mushroom, extracted twice, concentrated ten to one. Different substance, not different marketing.
The extract is identical in all four. Pick the one you'll still be taking in March. Capsules if you want it over in two seconds. Coffee if you already make one. Gummies if you won't swallow a capsule. Powder if there's a shake anyway.
Sixty days, first order, full refund — opened jar included. Delivery is 3–5 days, so there's time to find out.
Before you buy
Nothing here needs a leap of faith
Two months of mornings, one decision made once. If it isn't for you, we take the jar back opened.
