About this directory. Psyche Insights lists organisations for information only. A listing is not an endorsement, a recommendation or medical advice, and we do not take referral fees. We list only lawful, regulated services, registered clinical trials and professional training. We do not list retreats or anyone offering psychedelics outside the law. Psilocybin, MDMA, LSD and DMT are controlled drugs in the UK. Eligibility, availability and legal status differ by country and change often. Always check details with the provider or trial team, and talk to your GP or specialist before making any treatment decision. Paid placements are labelled “Featured · Paid placement” and never change our editorial descriptions. See our terms.
