International partnership
SACRUM × Rejuvyn
Rejuvyn is a Netherlands-based centre offering individual and group psilocybin programmes that encompass preparation, the lived experience and integration. In October 2026 we signed a letter of intent and became its official partner. Our part is what happens in Poland: careful preparation, readiness assessment and integration after returning home.
SACRUM does not administer, sell or broker psilocybin or any other controlled substance. Psilocybin is prohibited in Poland. Rejuvyn's programmes take place only in the Netherlands, and Rejuvyn is responsible for their compliance with Dutch law.

What we do, and what Rejuvyn does
Each party remains independent and responsible for its own work. Rejuvyn runs the programmes in the Netherlands; we support people who are considering them, preparing for them or coming back from them.
Conversation and readiness assessment
Before any decision is made.
We talk about motivation, health history, current medication and expectations. We are clear about limitations and risks, including when the honest answer is to advise against taking part. This is a psychological conversation, not a medical qualification or a guarantee of safety.
Psychoeducation and intention
Preparation that leaves no room for guesswork.
We help you name your intention, understand what can realistically be expected and prepare for difficult moments, so the decision is an informed one rather than a response to promises.
Continuity of support
Before, during and after, within agreed roles.
We stay in touch before travel and after return. The scope of support during the programme is being agreed with Rejuvyn and will stay within our competences. Rejuvyn is responsible for the programme itself in the Netherlands.
Integration after returning
Individually, in groups and in community.
The most important work starts after the experience: bringing what happened into everyday life. We offer it in individual sessions, groups and educational formats.
Shared commitment
What this partnership stands on
„The parties recognise that psilocybin-assisted processes are not a universal solution. They require individual assessment, appropriately qualified practitioners and clear respect for professional boundaries. Each party remains independent and responsible for its own actions, standards and legal compliance.”
From the SACRUM × Rejuvyn letter of intent, signed by both parties on 3 and 6 October 2026.
Standards we commit to
- rigorous preparation and thoughtful screening
- informed consent
- harm reduction
- confidentiality
- relational ethics and participant wellbeing
- sustained integration into everyday life

FAQ
Frequently asked questions
Does SACRUM administer or supply psilocybin?
No. We do not administer, sell or help anyone obtain psilocybin or any other controlled substance, in Poland or abroad. The programmes in the Netherlands are run solely by Rejuvyn, which is responsible for their organisation, delivery and compliance with Dutch law.
Is this legal?
Preparation and integration are psychological work and fully legal in Poland, regardless of where someone had their experience. Psilocybin is prohibited in Poland. Rejuvyn is responsible for the compliance of its programmes with Dutch law.
Can anyone take part in a programme?
No, and we say so plainly. Psilocybin-assisted processes are not for everyone. They require individual assessment, and some health conditions and medications are serious contraindications. That is why a conversation and readiness assessment come first, and the outcome may be advice not to take part.
When does it start and what does it cost?
We are not publishing dates or prices yet because they have not been set, and we will not guess. People on the waiting list will receive this information first.
I have already had such an experience. Can I start integration now?
Yes. Psychedelic integration is part of our offer independently of this collaboration and of where the experience took place. Sessions are conducted in Polish; you can start with a free fifteen-minute call.
