Microdosing Protocols Compared

Most of the conversation around microdosing collapses three different practices into a single word. The protocols people actually follow vary in cadence, in stated purpose, and in how much they ask of a nervous system. The differences are worth taking seriously, because they shape what you notice and what you miss.

What follows is a comparison of the three best-known schedules. None of them is settled science. The literature on microdosing has matured enough that we can describe how each protocol tends to land, but not enough to recommend one over another with confidence. Treat this as a way to ask a better question, not as a prescription.

The Fadiman protocol

The original. James Fadiman began collecting low-dose self-reports around 2011, and the cadence he described, dose one day then rest two, has become the default schedule for most people who try microdosing.

A typical week looks like this:

• ●Day 1: dose
• ●Day 2: rest, often described as an afterglow day
• ●Day 3: rest, baseline
• ●Day 4: dose again

Roughly two doses per week, with a clear contrast between dosing and non-dosing days. That contrast is the protocol's main contribution. Most of what is useful to learn about your own response lives in the off-days, not the on-days. If a particular kind of mental ease is present on Wednesday but absent on Friday, that pattern only becomes visible because the rhythm leaves room for it.

Cycles run four to six weeks, followed by two to four weeks off. The off-period is partly a tolerance reset and partly a check on whether the practice is doing what you thought it was. People often discover during the break that the things they attributed to microdosing were either still present (suggesting the change had taken root) or quickly absent (suggesting the dosing days were doing more carrying than the schedule implied).

The Fadiman cadence is most often a fit for: beginners who want a clear baseline; people working on mood, focus, or creative output; and those who do well with predictable structure.

The Stamets stack

Paul Stamets, the mycologist and psilocybin advocate, proposed a different schedule with an additional ingredient list. Four days dosing, three days off. The dose is typically combined with lion's mane mushroom (a functional mushroom with proposed neuroprotective properties) and niacin (vitamin B3, which produces a peripheral flush thought to help with distribution).

The rationale is built around neurogenesis and habit shifting. The combination has not been tested in controlled trials as a combined protocol, and the specific synergistic claims rest on inference rather than direct evidence. That does not make them wrong, but it does mean the Stamets stack carries a heavier load of theory than the Fadiman protocol does.

In practice, the more frequent dosing tends to be more stimulating. People who try it often report some combination of: subtle stimulation that compounds across the four-day block, increased creative or cognitive output during the dosing window, and difficulty sleeping if the dose lands too late in the morning or if caffeine is part of the routine.

The stack is most often a fit for: people drawn to the functional-mushroom rationale; those whose sleep and nervous system run robust enough to tolerate stimulation; and people approaching microdosing as a long-term experiment rather than a brief inquiry.

It is rarely the right starting point for sleep-sensitive people, or for those whose baseline already includes anxiety or low-grade stimulation.

Intuitive or once-weekly

The lightest of the three. One or two doses per week, taken when a particular day feels appropriate rather than on a fixed schedule. There is no single source for this approach; it has circulated in practitioner communities and tends to emerge organically in people who find that more frequent dosing pushes them past where they want to go.

The trade-off is straightforward. With less frequent dosing, less data accumulates. The kind of week-over-week pattern recognition the Fadiman cadence makes possible is harder to achieve when the dosing days are scattered. On the other hand, the load on the nervous system is lower, the risk of tolerance is minimal, and the practice tends to nest more comfortably alongside therapy, integration work, or other modalities.

The risk worth naming is dose drift. Without a fixed schedule, it is easy to gradually increase frequency without noticing. A practice that begins as one or two doses per week can become four without an explicit decision. If you find yourself reaching for it more often than you intended, that is information about how the practice is functioning in your life.

The intuitive approach is most often a fit for: people whose sleep is easily disrupted; those using microdosing as a supporting practice alongside something else; and anyone who notices stimulation easily.

Which one fits where

There is no single best choice, but there are reasonable starting points.

If you want a clear baseline and you are new to this: Fadiman.

If you are working on long-term cognitive support and your nervous system runs warm enough to handle more frequent stimulation: the Stamets stack.

If your sleep is fragile, or microdosing is one tool among many: once-weekly or intuitive.

If you are sleep-sensitive but want the contrast that a structured schedule provides: a modified Fadiman, with the dose taken before 8am and caffeine reduced or shifted later in the day.

The questions that matter more than the choice of protocol are these: what are you actually tracking, and what would change your mind. If you cannot answer either, the protocol is not the bottleneck.

What the protocols share

All three converge on the same handful of practices. Take the dose early in the day. Keep a journal that includes both dosing and non-dosing days. Cycle off every several weeks. Notice what persists across the off-period.

The decision worth pausing on is not which protocol but how to structure the inquiry. A four-week period with consistent journaling, attention to sleep, and a deliberate baseline period afterward will teach you more than a year of unstructured use across any of the three.

A note on caffeine

Caffeine compounds with both psilocybin and LSD in ways that often show up at night, even when both are taken in the morning. The mechanism is not perfectly understood, but the pattern is consistent enough across reports that it is worth taking seriously: more arousal during the day than either substance produces alone, less ability to wind down in the evening, and shorter or lighter sleep that night.

If you microdose and you also drink coffee, run the experiment at least once with reduced or delayed caffeine. The result is often informative.

Considerations

• ●All three protocols rely on the user being able to verify what they have actually taken. In jurisdictions where microdosing remains illegal, the substance and dose cannot be reliably verified. This is a real constraint, not a footnote.
• ●Anxiety and emotional volatility appear in roughly one in ten people in observational data. If a protocol seems to be making things worse rather than better, that is worth naming and pausing on.
• ●Chronic agonism of serotonin 5-HT2B receptors is a concern that has been raised in the long-term microdosing literature. The risk is thought to be dose-dependent and most relevant over very long durations of use. It remains understudied at microdose levels, but it is a sufficient reason to treat indefinite daily or near-daily dosing with caution.
• ●People with personal or family history of psychosis, schizophrenia, or bipolar disorder with psychotic features should approach with particular care, regardless of protocol.
• ●The strongest case for microdosing of any kind is as a time-limited inquiry, not a permanent practice. The practices most associated with reported benefit involve cycling, journaling, and a willingness to stop if the data does not support continuing.
