Microdosing protocols are recurring schedules people use to separate low-dose days from rest and observation days. The five approaches below are commonly discussed, but none is a medically established treatment schedule. Research has not yet established that psilocybin microdosing is safe or effective, according to the National Institute on Drug Abuse.
Use this guide to understand the differences—not as personal medical advice. Laws vary by location, and anyone with health concerns, a mental health condition, or prescription medications should speak with a qualified professional before making decisions.
Microdosing schedules at a glance
| Approach | Common pattern | Main reason people choose it |
|---|---|---|
| Fadiman-style | 1 day on, 2 days off | More time between dose days for observation |
| Stamets Stack | 4 days on, 3 days off | A repeating weekly structure |
| Every other day | 1 day on, 1 day off | A simple alternating calendar |
| Weekday schedule | Weekdays on, weekends off | A schedule tied to the workweek |
| Less-frequent schedule | Occasional dose days with longer breaks | More observation time and fewer dose days |
These patterns describe how people organize their calendars. They are not proof of benefits, safety, or the right amount for any individual.
1. Fadiman-style protocol: one day on, two days off
This schedule uses one dose day followed by two non-dose days. People often choose it because the space between dose days can make it easier to compare the day of use, the following day, and a return-to-baseline day.
A three-day cycle can also be easier to document. Record sleep, mood, energy, appetite, focus, unwanted effects, and any medication or lifestyle changes that might affect the comparison. Our microdosing tracking guide provides a simple list of observations to record.
2. Stamets Stack protocol: four days on, three days off
The commonly discussed Stamets Stack combines a four-days-on, three-days-off calendar with lion’s mane and niacin. It is more concentrated than the Fadiman-style pattern because it places several dose days together.
Do not treat the schedule or combination as a proven medical protocol. Ingredient amounts and individual reactions vary, and niacin can cause flushing and other unwanted effects. Review every ingredient and speak with a qualified professional if you take medication or have a health condition.
Our Stamets Stack capsule collection lists the amount and capsule count for each available product so you can compare the labels. For ingredient details, research limits, and safety checks, read the complete Stamets Stack protocol guide.
3. Every-other-day schedule
This approach alternates a dose day with a non-dose day. The calendar is easy to remember, but it creates more dose days than a one-day-on, two-days-off schedule.
Because frequent use may make changes harder to interpret, consistent notes matter. If you notice unwanted effects or difficulty functioning normally, stop and seek appropriate professional guidance rather than increasing the amount or frequency.
4. Weekday schedule with weekends off
Some people tie their schedule to Monday through Friday and use the weekend as a break. The appeal is convenience, not stronger evidence. A workweek schedule can also make it harder to separate possible effects from workload, sleep, caffeine, and weekday stress.
Never assume a low amount makes driving, work, childcare, or operating equipment safe. Do not drive or perform safety-sensitive tasks if you feel any effect.
5. Less-frequent or observation-first schedule
A less-frequent approach uses longer gaps between dose days. People may choose it to create more observation time, reduce the number of variables, or avoid building a routine before they understand their response.
For someone focused on learning from their notes, fewer dose days can make the comparison clearer. It also provides more time to review sleep, mood, appetite, and unwanted effects before making another decision.
How to compare microdosing protocols
Start with the questions that affect safety and your ability to evaluate what happened:
- Can you remain fully functional? Any noticeable impairment is a reason not to drive, work in a safety-sensitive setting, or care for others alone.
- Can you track consistently? Use the same measures and time of day so your notes are comparable.
- What else changed? Record sleep, alcohol, caffeine, medications, stress, illness, and major routine changes.
- Are there unwanted effects? Anxiety, confusion, nausea, increased heart rate, and raised blood pressure are among the risks described by NIDA.
- Is it legal where you are? Federal, state, and local rules can differ and change. Check current rules before making decisions.
Capsules, chocolates, and starter bundles
The format does not replace careful label reading. Compare the stated amount, ingredients, count or portions, and storage instructions on each product page. Browse microdosing capsules, mushroom chocolates, or starter bundles to review the available formats.
What current research says
Interest in microdosing is ahead of the evidence. NIDA states that research has not established microdosing as safe or effective. The FDA continues to support controlled research into psychedelic drugs, but research settings—with screening, standardized products, and professional oversight—are not the same as unsupervised use.
That uncertainty is why a schedule should never be treated as a promise of improved mood, focus, creativity, or mental health. Approach claims carefully, use reliable sources, and involve a qualified professional when health or medication questions are involved.
