Microdosing Psychedelics


Our goal is to help people - world wide - know more about microdosing psychedelics. Due to the increasing number of requests, we can no longer answer each of you personally. This website is under construction. We are adding new research protocols to begin at the end of July. Please check back then to read about what we've learned so far, share your stories, enjoy stories and art about microdosing, connect to other resources, and participate in follow up surveys. Thank you so much for your interest in microdosing and participation and engagement up to this point.

This website has information on microdosing, including a protocol many people have used to microdose safely. What we offer is information on safe and effective microdose use. We do that by enrolling people in studies, then recording and analyzing their reports. We then share the results. We also advise and support other research projects related to microdosing. We will not be including comments on higher dose effects, sacred uses, MDMA, issues of legality, training, or other current research and resources. Here is a link to our Frequently Asked Questions.

These are the three most frequently asked questions:

  • How much is a microdose? Most people start at 1/20 to 1/10 of a recreational dose of whatever substance they are trying and adjust based on their experience. If you are experiencing visual effects, you have taken too much. This is 5-10 micrograms of LSD, slightly more (7-12 mcg) of 1p-LSD. This is 0.1-0.4 grams of psilocybin mushrooms.
  • How often are microdoses taken? Most participants dose every three days.
  • Is microdosing right for me? Only you can make that determination. There is more information about who has benefited so far and possible risks in the full FAQ.

Over 1500 participants have reported their experiences of microdosing as of this writing, and submitted narrative reports and daily data. We are taking time to read and analyze and report on all the data. We are continuing to gather data. You can enroll here and submit daily information here. Since people who check in more often tend to do better, we recommend you check in more often.

Currently enrolled participants, please continue to send us your information.

Whether or not you enrolled in the daily data study, if you've tried microdosing using our protocol or differently, we appreciate learning about your experience. Please send us a written report of any length at psychedelicsresearch@gmail.com, or use the narrative reporting form.

We are especially interested in accepting participants who have specific health conditions to expand our knowledge into those areas. We are particularly interested in the experiences of those with histories of stroke, traumatic brain injury, severe headache or menstrual disorders, and those diagnosed with depression and bipolar disorders. We are also interested in the experiences of those people for the control/comparison group.

We specifically do not recommend that people with colorblindness, who live with diagnoses of psychotic disorders or along the autism spectrum try microdosing. People with colorblindness report lasting visual distortions from microdosing. Literature suggests people with psychotic disorders may be harmed by psychedelics. In our experience, people with diagnoses along the autism spectrum seem to require dosages that far exceed what is traditionally considered microdosing.

We are not able to offer information about how to obtain psychedelics, which are not yet legal in most countries. We also are not able to offer opinions on specific centers or individual guides.

Media or academic/clinical researchers: Please make your requests to psychedelicsresearch@gmail.com.

Please DO NOT ASK US about: how or where to find substances.

Thank you for your interest and support,
