The Magic Truffle Calculator helps you find a measured, harm-reduction starting dose of psilocybin truffles based on the variety you have, your body weight, your experience level, and whether your truffles are fresh or dried. The principle is simple: start low, go slow. You can always take more — you can’t take less.
| Level | Fresh truffles | What to expect |
|---|---|---|
| Microdose | 0.5 – 1.5 g | Sub-perceptual. Subtle lift in mood and focus, no visuals. |
| Museum (light) | 5 – 7 g | Enhanced mood, music and colour. Gentle and easy to manage. |
| Moderate | 10 – 15 g | A real journey — visuals, emotion and introspection. |
| Strong | 15 – 22 g | Immersive and intense. A sober sitter is advised. |
| Heroic | 30 g + | Overwhelming. For the very experienced, with a sitter. |
Dried truffles are roughly one-third of these amounts. Potency varies batch to batch — always begin at the low end.

A common starting point for fresh, medium-potency truffles is about 5–10 g for a light-to-moderate experience, 10–15 g for a full journey, and 15 g+ for a strong one. Your ideal amount depends on the variety’s potency, your body weight, your experience, and whether the truffles are fresh or dried. The calculator on this page estimates a personalised range.
A microdose is roughly 0.5–1.5 g of fresh truffles — a sub-perceptual amount that lifts mood and focus without visuals. See our microdosing guide for schedules and tips.
If it is your first time, start low — around 5–7 g of fresh medium-potency truffles. The calculator caps first-timers at a moderate level for safety.
Truffles are roughly two-thirds water, so dried truffles are far more potent by weight — about one-third the weight of fresh for the same effect (a 3:1 ratio).
Effects usually begin 30–90 minutes after taking truffles, peak for about 2–4 hours, and taper over another 1–2 hours — around 4–6 hours total.
Utopia, Hollandia and Valhalla sit at the top of the scale (5/5), followed by Pandora, High Hawaiians and Dragon’s Dynamite (4.5/5). Mexicana is the gentlest (2.5/5).
It varies widely by country. Psilocybin truffles occupy a legal grey area in the Netherlands but are prohibited in many other places. Always check your local law.
