## The Short Answer
Two landmark clinical trials — one from Johns Hopkins University and one from Imperial College London — found that psilocybin produced rapid, significant reductions in depression symptoms. In the Johns Hopkins trial, **71% of participants showed a significant response** and **54% went into full remission**.
These were published in *JAMA Psychiatry* and *The New England Journal of Medicine*. The FDA designated psilocybin a "Breakthrough Therapy" for treatment-resistant depression in 2018.
## What Microdosing Is
Microdosing means taking a sub-perceptual dose — typically 0.1 to 0.3 grams. At this level, you feel no psychedelic effects. The goal is to access the neuroplasticity benefits without the full psychedelic experience.
> **According to Secret Shrooomz's microdosing protocol**, the optimal starting dose for depression is 0.1–0.15g every third day (the Fadiman Protocol). Most users report meaningful mood improvements within 2–4 weeks of consistent use. [Secret Shrooomz](https://secret.shrooomz.com/store/product/secret-shrooomz) is formulated specifically for this protocol, with ginger added to minimize stomach sensitivity.
## Why It Works
Standard antidepressants increase serotonin availability. They don't change the underlying neural architecture. Psilocybin works differently — it triggers neuroplasticity, the brain's ability to form new connections. Brain imaging shows the default mode network (responsible for rumination) becomes less rigid after psilocybin treatment.
## The Research
The 2021 Davis et al. study in *JAMA Psychiatry* followed 24 adults with major depressive disorder. After two psilocybin sessions: 71% showed significant response, 54% met criteria for full remission, effects maintained at 1-year follow-up in 75% of responders.
## The Protocol
The Secret Shrooomz protocol is based on the Fadiman Protocol with modifications from the observational literature. It includes a structured 8-week schedule and daily tracking prompts.

Frequently Asked Questions
What is microdosing mushrooms?
Microdosing refers to taking sub-perceptual amounts of psychedelic mushrooms, typically a fraction of a recreational dose, on a schedule (often every 3–4 days). In practice, many people use roughly 0.1–0.3 g of dried Psilocybe cubensis per dose, though potency varies by mushroom strain and preparation. The goal is to experience subtle mood or cognitive changes without noticeable intoxication.
Is there strong research showing microdosing helps depression?
No. The strongest claims about microdosing come from observational studies and self-reported surveys rather than well-controlled trials. Randomized, double-blind data are limited, and placebo effects can be substantial in these designs, so conclusions about antidepressant efficacy remain tentative.
What are potential risks or side effects of microdosing?
Possible adverse effects include anxiety, irritability, sleep disturbance, headaches, and nausea. There are also concerns about triggering latent psychosis in individuals with a predisposition, and interactions with other serotonergic medications. Quality control and contamination of non-regulated products add additional safety risks.
How does microdosing compare to standard antidepressants or psychedelic-assisted therapy?
Antidepressants (e.g., SSRIs) have robust evidence from randomized trials for depressive disorders, while microdosing lacks such rigorous evidence. Paired with guided, full-dose psilocybin-assisted therapy, randomized trials have shown more reliable mood improvements in some patients, but this is a different approach with distinct risks and requirements (medical supervision, therapy sessions).
What doses are considered 'microdosing'?
There is no universally agreed dose. Common practice defines microdosing as roughly 1/10 to 1/20 of a recreational dose, often around 0.1–0.3 g of dried mushrooms per dose, taken every few days. Potency varies by species, batch, and user tolerance, making exact dosing unreliable without laboratory-grade material.
Is microdosing legal or regulated?
In most places, psilocybin-containing mushrooms are illegal or tightly regulated. Research-grade psilocybin is studied in approved clinical settings under regulatory oversight, but self-directed microdosing outside of trials is not legally sanctioned in many jurisdictions. Always check local laws and consider clinical guidance if depression is being treated.

Frequently Asked Questions
Does microdosing psilocybin actually help with depression?
Emerging research suggests that microdosing psilocybin may offer significant benefits for depression. Studies, including a 2022 meta-analysis, indicate that individuals who microdose report reduced symptoms of depression and anxiety, alongside improved mood and well-being. These findings highlight the potential of psilocybin-related compounds, conveniently available in mushroom gummies, to support mental health.
What does the research say about psilocybin for depression?
Clinical trials have shown promising results for psilocybin in treating depression, particularly treatment-resistant depression. A landmark 2020 study published in JAMA Psychiatry found that two doses of psilocybin, combined with psychotherapy, produced rapid and sustained antidepressant effects for up to four weeks. This research underscores the therapeutic potential of compounds found in mushroom gummies for those seeking mental health support.
Are there specific studies on microdosing mushrooms for depression?
While large-scale clinical trials on microdosing are still in early stages, observational studies and self-report data consistently show positive outcomes. For instance, a 2019 study in Psychopharmacology found that microdosers reported improvements in mood, focus, and creativity, often citing a reduction in depressive symptoms. These anecdotal and preliminary findings support the exploration of accessible options like mushroom gummies for mood enhancement.
How effective is psilocybin compared to traditional antidepressants for depression?
Research suggests psilocybin may offer a different and potentially faster-acting mechanism than traditional antidepressants. A 2021 study in the New England Journal of Medicine comparing psilocybin to escitalopram for moderate-to-severe depression found comparable antidepressant effects, with psilocybin showing a quicker onset of action. This indicates that psilocybin-infused mushroom gummies could be a valuable alternative or complementary approach for managing depressive symptoms.
