Tricycle Day is a psychedelics newsletter made by the team at Althea and written by Henry Winslow and Sasha Silberberg. Every Friday it runs a column called "Ask a Guide Anything." A reader sends in one question, the question goes out to a network of licensed psilocybin facilitators, and several of them are quoted on it.
Maria (Masha) Steiner-Renoir, who founded this practice and who also works as a licensed facilitator through her separate practice, MycoMuse, has now been quoted in nine issues in a row, July 17 through September 11, 2026. The newsletter credits her as Masha Steiner-Renoir; her facilitator profile is on Althea, the platform behind it.
The nine questions
- July 17: What do I do with a memory that surfaces during a journey if I can't tell whether it's real?
- July 24: Can psychedelics change your personality?
- July 31: How do you work with anger or rage that comes up during a journey?
- August 7: What are the tradeoffs between journeying outdoors in nature and indoors at a center?
- August 14: What can I do in the moment when a journey turns difficult?
- August 21: What should parents of young kids consider before trying psychedelics?
- August 28: How do mushrooms compare to San Pedro, and when might one be a better fit than the other?
- September 4: What should someone on a GLP-1 drug know before working with psilocybin?
- September 11: How do I talk to my family about my upcoming journey so they know how to support me?
Space is tight, and each issue runs several guides side by side on the same question, so what survives the edit is usually the most usable sentence a person had. Three of hers, in the newsletter's own words.
On anger that arrives partway through a session:
"Where do you feel it in your body? If your anger could speak, what would it say? Often, anger is protecting something more vulnerable underneath."
On how slowly a change in personality arrives, when it arrives:
"The change is usually subtle and unfolds over time, not all at once."
And on what a family can actually do for someone who has just been through it:
"Let them know you may feel more open and sensitive, so gentle presence without questions or expectations can be incredibly supportive."
Why a psychiatric prescriber turns up in that column
MindMorph is a psychiatric practice. It does not provide psilocybin services; that work is MycoMuse's, licensed and regulated separately under Colorado's Natural Medicine program and Oregon Psilocybin Services, and the two stay deliberately separate. Look at what those nine weeks covered, though. Sleep debt and postpartum months. A GLP-1 prescription, and what the guides made of it. A memory nobody can verify. What to say to your family. Those are questions about a person's history, their nervous system, and their medication list, which is the territory a prescriber works in. The preparation and integration offered here are for MindMorph's own treatments, ketamine and Spravato, not for a psilocybin journey. The medication list is the part that carries across: whatever else someone is doing, the interplay between their prescriptions and any journey belongs in a conversation with the clinician who manages them.
Where to read more
Her own account of all nine, with more than the newsletter had room for, is on the MycoMuse journal: Nine Fridays in Tricycle Day. The August 28 answer, mushrooms and San Pedro, already has its own post here: two medicines, two temperaments. For the psychiatric side of this work, start with psychedelic integration therapy and the monthly integration circle, or meet Masha.
If you are in crisis, call or text 988 (Suicide & Crisis Lifeline) or call 911. This practice does not provide emergency services.
