Magic mushroom compound may turn back the biological clock — a trial investigates
NCT ID NCT07719088
First seen Jul 22, 2026 · Last updated Aug 18, 2026 · Updated 4 times
Summary
This study tests whether psilocybin, the active compound in magic mushrooms, can influence biological markers of aging in healthy adults aged 60 to 80. Participants receive one, two, or three doses of 25 mg psilocybin or join a wait-list group. Researchers will measure changes in epigenetic clocks, telomere length, and sense of purpose over 12 months to see if the drug might slow or reverse aspects of aging.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a single 25 mg capsule of psilocybin, given one, two, or three times at four-week intervals
- What this could lead to
- If psilocybin measurably slows or reverses biological aging markers, it could open a new path for healthy-aging interventions.
- What could go wrong
- This is a small Phase 1 dose-ranging trial, not designed to prove anti-aging effects. Psilocybin can cause intense psychological experiences and may not be safe for everyone.

Inclusion Criteria: * English speaking and able to provide informed consent and complete study procedures * Medically healthy, as determined by the screening physician, with no significant medical conditions that would interfere with participation or affect the safety of the subject. Exclusion Criteria: * History or presence of any psychiatric or medical condition that, in the opinion of the investigator, could pose a safety risk, interfere with participation, or confound study results. * Abnormal ECG at screening that may increase risk during participation (e.g., prolonged QTc, arrhythmias, or other clinically significant findings as determined by the study physician). * Unwilling or unable to discontinue medications that may interfere with study participation, as determined by the investigator.
