Microdosing means consuming a minimal dose of a psychedelic substance. For magic truffles, this applies to about 1/10th of a dose that normally gives a psychedelic experience.
There are different protocols and on average you take this dose for one to two months. Then a break of about two to four weeks. This time can be used to evaluate whether it has benefits in daily life. Microdosing will definitely not make you trip, not even a little bit. People who microdose do experience very small subtle effects. Microdosing works on a sub-perceptual level. As a result, you experience no psychedelic effects, no visual abnormalities and you can function normally during your daily activities.
