Take part in Scientific Research!
At Rejuvyn, we deeply value the power of scientific inquiry into the effects of psychedelic medicines on human health. While we are currently experiencing the so-called “third wave” of the psychedelic renaissance, the field still faces significant challenges. These include designing robust studies, addressing ethical concerns about taking measurements during altered states of consciousness, difficulties in developing effective placebos and securing adequate funding.
Despite these hurdles, clinical research is gradually progressing. However, there remains a critical need for studies that can authentically capture the profound benefits of ceremonial settings.
In light of this, Rejuvyn is proud to partner with Leiden University in the Netherlands to advance research into the short- and long-term effects of psychedelic retreats. Together, we aim to explore their impact on wellbeing, mental health, brain functionality, and more.
Our Partners
The PRSM lab studies Psychedelic, Religious, Self-transcendent, and Mystical (PRSM) experiences using a variety of methods and according to open science principles.
The lab is based in the Cognitive Psychology Unit at Leiden University, Faculty of Social Sciences, and is led by associate professor Dr. Michiel van Elk. Michiel has a deep interest in altered states of consciousness, as induced through psychedelics, meditation, and other means. Two PhD candidates working with Michiel, Huseyin Beykoylu, and Xaver Funk lead Study 1 and 2, respectively.
Current Studies we are partnering with
Description
An Observational Study on the Effects of Psilocybin Truffle in a Retreat Setting. This study examines how psilocybin-containing truffles used in a retreat setting can change aspects of one’s experience and mental processes, such as the sense of well-being, meaning in life, and mindfulness. The study also aims to explore how the retreat setting contributes to potentially lasting changes in one’s experience and personality. All it requires is a phone app and 2 minutes of your time to answer questions regarding your psychological state.
If you have any questions before or after participating in this study, you can contact the research team via retreatESM.study@fsw.leidenuniv.nl, or the principal investigator: Michiel van Elk (m.van.elk@fsw.leidenuniv.nl).

Description
This study investigates the changes in brain connectivity induced by participation in a psychedelic retreat and the associated changes in personality and well-being. The study involves two in-person sessions at Leiden University involving fMRI brain scanning within three days before and after the retreat, as well as three short online follow-up surveys in the following weeks. As a recompensation, you will get a T-shirt and a visualization of your personal brain connectivity changes. In addition, we will reimburse any travel cost to and from the lab within the Netherlands.
