how to use this kit



Truffles: The pre-measured microdoses weigh 1 gram, this is a quantity that works well for most microdosers, but not for all. Everyones tolerance to psilocybin varies, finding the dose that is optimal for you is known as "finding your sweet spot" learn more about his process here.

capsules: take two lions mane capsules daily with food.



There are three simple ways to consume microdoses, chewing, brewing a tea or using lemon juice. Check out our step by step instructions



We reccomend following the Fadiman protocol in which you take a microdose every 3 days; 

This is a recommended protocol as it helps lower the rate at which you build a tolerance- meaning you can microdose for 6-8 weeks before needing a 2 week break to give the brain and body enough time to reset to a baseline tolerance. Learn more about this protocol and others here.



Our microdoses are a fresh product, they can be kept in a refrigerator for up to 6 weeks and one week outside the fridge. You can store our capsules in a dry and dark environment such as a kitchen cupboard. 

We make a conscious decision to not vacuum seal our truffles to minimise upsetting stomachs and preserve their potency.  Our microdoses are packaged with a small amount of oxygen to preserve their vitality. Occasionally you may notice a white mould-like growth on them. This is simply their natural root system attempting to regrow. It is completely harmless and safe to consume.

Lions mane | Hericium erinaceus


Our lions mane mushrooms are sourced from pristine, ancient forests in China, where traditional farming methods have been perfected over generations. Grown away from urban pollution, these farms benefit from optimal climate and soil conditions.

100% fruiting body | 11:1 concentrated extract 

How the capsules are made

  • Mushrooms are bred on a natural mixture of sawdust, wheat bricks, sugar cane, and lime.

  • After reaching maturity, they are naturally dried to preserve quality, either in sunlight or controlled drying ovens.

  • Handpicked for quality, only the best mushrooms proceed to the next phase.

  • Dried mushrooms are ground into a fine powder and processed into a highly concentrated extract through hot water extraction, ensuring optimal bioavailability of vital nutrients.

Key features of their growing environment

  • Slow growth of the fruiting body ensures high bioavailability.

  • Our products contain no chemicals, pesticides, or synthetic additives.

  • Breeding grounds are used only once to maintain soil nutrients, with residual material repurposed for sustainability.
