Low-Dose Sessions
Low-Dose Psilocybin Sessions in Oregon: More Than a Microdose, Less Than a Journey
A gentle dose with a licensed facilitator at a licensed service center. From $75 in a small group, or $250 privately. The lowest-commitment way to find out what this work is like.
A low-dose psilocybin session with Ayeterra is a complete, legal session with a licensed facilitator at a licensed service center, at a dose most people feel clearly without being taken all the way in: 4.99 mg in a small men’s or women’s group from $75, or 4.9 to 9.9 mg privately for $250, psilocybin included. It is an introduction, not a sample, and not a discount version of a full session.
From Ayeterra’s Oregon-licensed facilitators. Last updated September 16, 2026.
What does a low dose of psilocybin feel like?
Present, softened, and still yourself. Colors a little brighter, thoughts a little looser, feelings closer to the surface. It is enough to learn what the medicine is like and how you respond to it, and not enough to lose the thread.
- Under 5 mg (the group dose): most people feel it clearly; a one-hour minimum session by Oregon rule, usually about two hours in practice
- 5 to 9.9 mg (the private range): noticeably more; a two-hour minimum session, with room to go a little deeper if you and your facilitator choose
- Not a full journey. Full sessions run 20 to 50 mg over four to six hours; this is a different thing on purpose
Is a low-dose session the same as microdosing?
No, and the difference matters legally and practically. Microdosing means sub-perceptual amounts taken at home over weeks; a low-dose session is a perceptible dose, taken once, at a licensed service center with a facilitator.
| Microdosing | Low-dose session (Ayeterra) | Full session | |
|---|---|---|---|
| Amount | Roughly 0.1 to 0.3 g dried, below the threshold of feeling it | 4.99 mg (group) or 4.9 to 9.9 mg (private) of psilocybin analyte | 20 to 50 mg |
| Do you feel it? | Not supposed to | Yes, clearly, while staying yourself | Yes, fully |
| Where | At home, repeatedly | A licensed Oregon service center, once | A licensed Oregon service center |
| Legal in Oregon? | No; possession outside a licensed session is a crime | Yes | Yes |
| Supervised? | No | Licensed facilitator present throughout | Licensed facilitator present throughout |
| Evidence | Mixed; placebo-controlled trials mostly find small or no effects | Not studied as its own thing; it is a gentle version of the supervised model | The model the clinical trials used |
Group or private?
Low-dose group session
- 4.99 mg, a gentle dose most people feel clearly
- Small men’s or women’s group
- Licensed facilitator present throughout
- Open to anyone 21+, no application, no means test
Private low-dose introduction
- 4.9 to 9.9 mg, chosen with your facilitator
- Private: just you and your facilitator
- Meet the facilitator and the setting before a full session
- Room to feel a little more than the group dose
Price should never be the reason someone does not have a session. Sliding-scale access is real and handled on the consultation, with no forms and no proof of hardship. The $75 group exists so there is a real doorway into this work for anyone.
Who is a low-dose session for?
- People who have never taken psilocybin and want to meet it gently before deciding on a full session
- People who are nervous about losing control, and want to learn that they can stay present with it
- People who want to meet a facilitator and a service center before committing $750 or $2,000
- People for whom cost is the barrier. The group is $75 and it is a real session
- People who are simply curious, which is a good enough reason
The same screening, preparation, facilitator presence, tested product, and follow-up as every other format. Oregon does not have a lighter set of rules for lighter doses.
Both low-dose formats share the same legal protections as a full session.
Read the safety and screening page →What does it cost?
- Group: from $75 per person, psilocybin included
- Private: $250, psilocybin included
- No add-ons, no facility fee, nothing sold afterward
Every price includes preparation beyond Oregon’s one required session, the session room, and integration support.
See every price and what it includes →Low-dose questions
Is $75 really a whole session?
Yes. Screening, a preparation session, the session itself at a licensed service center with a licensed facilitator, the psilocybin, and a follow-up. It is short and it is gentle; it is not partial.
Will I feel anything at 4.99 mg?
Most people do, clearly. A few feel very little, which is itself useful information about how you respond. Nobody is taken all the way in at this dose.
Can I drive afterward?
No. The transportation rule applies at every dose. Arrange a ride.
What happens after a low-dose session?
Your facilitator follows up within 72 hours. Many people go on to a full group or one-on-one session; some decide this is enough; some decide it is not for them. All three are good outcomes of a $75 session.
Why are the groups men’s and women’s?
Because a lot of people find it easier to be open in a room of people who share that, and the format is short enough that the groups can run separately. Say what you need on the consultation.
Can I microdose psilocybin legally in Oregon?
Only inside a licensed session, which by definition is not microdosing at home. Possession of psilocybin outside Oregon’s program is a crime, and take-home doses are not allowed. If what draws you to microdosing is a gentle, low-commitment first experience, a low-dose session is the legal version of that, with a facilitator in the room.
Is there a low-dose session near me in Ashland or Eugene?
Low-dose formats are Portland-only for now. Ashland offers one-on-one full sessions. This page will say so when that changes.

Ayeterra provides legal psilocybin facilitation in Oregon through facilitators licensed by the State of Oregon, under Oregon’s regulated psilocybin program. These services are not medical care, psychotherapy, or a substitute for diagnosis or treatment by a licensed medical or mental health professional, and anything we share is general education, not medical advice. Psilocybin is not right for everyone: participation is limited to adults 21 and over and involves screening. We do not promise specific outcomes, and experiences vary. If you are in crisis or thinking about harming yourself, call or text 988. Psilocybin services are not a substitute for crisis care or treatment.
