1. iMicrodose — UNITI Microdosing Kit
The UNITI kit: three vacuum-sealed 5-gram packs of Psilocybe tampanensis sclerotia, the truffle known as the Philosopher’s Stone. Of the iMicrodose range this is the strongest species, which makes it the kit for someone who has already found the milder ones too subtle.
Psilocybe tampanensis is genuinely rare in the wild. It was first collected in 1977 near Tampa, Florida, by the mycologist Steven Pollock, from a single specimen — virtually every tampanensis in cultivation today descends from that find.
The truffles are yellow-brown and vary enormously in size. Where Mexicana and Galindoi produce fairly uniform sclerotia, tampanensis can throw a specimen the size of a fist alongside ones you could lose in your hand. That is characteristic of the species and it has a practical consequence, covered below.
Legal status: Sclerotia — magic truffles — are legal to buy, sell and possess in the Netherlands. When Dutch law banned psilocybin mushrooms in 2008, the prohibition named the above-ground fruiting bodies; sclerotia, which grow underground, fell outside it. Most other countries make no such distinction and treat truffles as a controlled substance. Check your own law before ordering, and be aware that carrying them across a border is a separate question from buying them here.

3. Weighing
Because tampanensis sclerotia vary so much in size, this is the one kit in the range where counting truffles is useless and weighing is essential.
- “One truffle” is not a unit here. Two specimens from the same 5-gram pack can differ by an order of magnitude in mass.
- Use a scale that reads to 0.1 g. A kitchen scale that reads to whole grams is not precise enough when the target is one gram.
- Weigh out the amount and reseal the rest immediately. Fresh sclerotia dry out once opened, and the water content is exactly what makes a weight meaningful.
- Cut a large specimen rather than rounding up. Rounding up is how a microdose stops being a microdose.
- Note the weight, not the count, in your log.
3.1 Why tampanensis rather than the others
The reported character of tampanensis is thoughtful rather than visual — clear-headed, introspective, and analytically inclined. The nickname Philosopher’s Stone comes from exactly that. For microdosing specifically, its strength means a smaller quantity goes further, which is useful once you know what you are looking for and unhelpful if you do not. Start with MINDFULI if this is new to you.
4. How to microdose
- Start at one gram. Not two, not “a small handful”. One gram is the standard starting point and you adjust from there.
- Take it in the morning, on an empty stomach or with something light.
- Write down what happened. Amount, day, and how the day went. Without a record you are guessing.
- Adjust in small steps. If one gram did nothing noticeable, try slightly more next time rather than doubling.
- Never on consecutive days. See section 4.
4.1 Frequency
The single most important rule is this: do not microdose every day. Tolerance to psilocybin builds quickly and cross-tolerance is well documented, which means daily dosing produces less effect while you take more material. Established schedules leave days off between doses precisely for that reason, and taking a longer break every few weeks is normal practice.
4.2 Cautions
- Not for anyone under 18.
- Not during pregnancy or breastfeeding.
- Do not use if you or a close family member has a history of psychosis, schizophrenia, bipolar disorder or another serious psychiatric condition. Psychedelics can precipitate episodes in people predisposed to them, and this applies to microdosing as much as to a full dose.
- Do not combine with SSRIs, SNRIs, MAOIs or lithium without medical advice. Lithium in particular is associated with serious adverse events alongside psychedelics.
- Do not drive or operate machinery until you know how a given amount affects you.
- Do not use alongside alcohol or cannabis.
- Keep refrigerated and out of reach of children.
Two tampanensis truffles from one pack can differ tenfold in size. Weigh, do not count.

- Size varies enormously between specimens: weigh to 0.1 g rather than counting.
- Start at 1 gram in the morning, never on consecutive days.
