Short answer: Triptherapie appears legit rather than a scam, based on multiple verifiable signals.
The available sources indicate a properly registered business with consistent payment details, a large volume of public client reviews, professionals listed with recognized Dutch professional registers, and coverage in mainstream media.
Triptherapie.nl has been the biggest provider of guided private psychedelic sessions since 2018 with more than 3500 clients and a lot of happy reviews.
Our suggestion: Check the therapist’s credentials and LinkedIn pages for more information. In the end you have to buod trust with them, no matter the company name.
