What people mean by microdosing

Microdosing describes taking an amount of a psychedelic substance small enough that it does not produce a noticeable altered state.

People are interested for a mix of reasons: mood, focus, creativity, and often a sense that conventional approaches have only gone part of the way. That curiosity is reasonable. What is less reasonable is the confidence with which microdosing is often described online.

What the research currently suggests

Several placebo-controlled and self-blinded studies have found that people who take microdoses and people who unknowingly take placebo both report improvements, and that the gap between them is much smaller than enthusiasts assume. Expectation appears to do a great deal of the work. That does not make the experience meaningless, but it does mean the mechanism is unsettled.

What the research does not establish

There is no established dosing standard, no long-term safety data, and no evidence that microdosing treats any medical condition. Frequent use of some substances raises cardiac questions that have not been resolved.

Before anyone considers it

Psilocybin is a controlled substance in most jurisdictions. Interactions with psychiatric medication — particularly SSRIs, MAOIs and lithium — are a genuine medical question, not a forum question. A personal or family history of psychosis or bipolar disorder changes the risk picture substantially.

The honest summary: this is an area of active research, not an established practice, and anyone considering it should be talking to a qualified professional rather than to strangers.
