How many grams of Atlantis truffles?

Most people take 5 to 15 grams of fresh Atlantis truffles. Around 5 to 7 grams gives a light experience, 8 to 12 grams a clear trip with visuals, and 13 to 15 grams a strong one. If you have never taken truffles, start at the low end and stay there for your first session.

These ranges come from shop guidance and user experience. They are a starting point, because the amount of psilocybin in a pack varies more than most people expect.

Doses at a glance

A full 15 gram pack is a strong dose for one person. If you take less, weigh it on a kitchen scale instead of guessing by eye.

Why the same dose can feel different

Laboratory measurements of commercial truffles found 0.6 to 1.7 milligrams of psilocybin per gram of fresh truffle (Pellegrini et al., 2013). Ten grams from one batch can therefore contain almost three times as much as ten grams from another. For comparison, clinical studies with psilocybin often use a single dose of 25 milligrams.

Other factors matter as much:

• Body weight. A heavier person usually needs a little more for the same effect.
• Stomach contents. On an empty stomach the effects come faster and stronger. A large meal can delay them by an hour and blunt them.
• Freshness. Truffles slowly lose potency. Blue spots appear where psilocin oxidises; they are harmless, but a truffle with a lot of blue has lost some strength.
• Medication. SSRI and SNRI antidepressants often weaken the effect, even months after stopping (Gukasyan et al., 2023). Do not compensate by taking much more.
• Tolerance. After one session, a second dose within a week works noticeably less.

How to take them

Eating them. Chew the truffles well and swallow. The taste is bitter and nutty. Take them on an empty stomach, or three to four hours after a light meal.

As tea. Chop the truffles finely, pour over hot water of around 70 to 80 °C, steep for 15 to 20 minutes and strain. Many people find tea easier on the stomach. The effects begin sooner and the peak can be shorter and more intense.

Lemon. Some people soak chopped truffles in lemon juice for 20 minutes before eating. Users report a faster and stronger onset. There is no good research on it, so think of it as a way to make the same dose stronger and adjust down.

Wait before taking more

The most common dosing mistake is impatience. Nothing happens for 40 minutes, so someone eats a second portion, and then both arrive at once. Give it at least 90 minutes before deciding the dose was too low. Better still, decide in advance that you will not take more that day.

Microdosing

Microdosing means taking a sub-perceptual amount, around 0.5 to 1 gram of fresh truffle, a few times a week for several weeks. The largest placebo-controlled study so far, with 191 participants, found no meaningful difference between the people who took a microdose and those who took a placebo (Szigeti et al., 2021). Much of what people notice is likely expectation.

Pre-portioned microdosing packs make dosing easier than cutting a 15 gram pack into small pieces.

Pack sizes

The 30 and 60 gram packs suit a group, or two sessions a few weeks apart. Fresh truffles keep for a limited time, so do not buy more than you plan to use. Read the safety page before your first session.
