be careful in 2025

Professor is REMOVED from the list on LL website !!!!!!!! I read a lot of bad review on trustpilot. One guy died in France due to RC from professor. Did not receive my package in 2025. I would be careful ordering now.

Top producten en goede service

Kwaliteot gegarandeerd bij de professor. 4mpd zalog om te roken evenaals nep. A-pcyp ook een leuk rookbaar stofje. En de keuze lsd en benzodiazepines. Prachtig allemaal. Allemaal getest en goedgekeurd! Go for it en bestel vandaag nog.

Toujours au top

Très satisfaite : beaucoup de choix pour le moment (dommage que tous les produits outlet vont disparaître cependant, car il y en a des très intéressants). Les produits semblent de qualité. La livraison est rapide. Les réponses par mail le sont aussi. Très bon service, longue vie à vous.

Un site web pratique avec des produits de qualité

J'ai fais plusieurs achats sur Professor.nl, en tant qu'invité au début, je ne voulais pas perdre du temps à créér un compte sur un site qui ne me satisfaisait pas. Croyez moi, j'ai de l'expérience dans ce domaine et j'ai souvent été déçu. J'ai commandé à plusieurs reprises sur professor.nl, et à ce jour, je n'ai jamais été déçu par les produits que j'avais acheté ! Je vous recommande vivement ce site !

Passer au niveau supérieur, industriel rien n'est laisser au hasard surtout pas la qualité

Très bien depuis quelques mois que j'y suis depuis j'ai fait plusieurs grosse commande toujours très bien protéger toujours arrivé à bon port c'est l'affaire de quelques jours 3, 4, 5 environ pour ma part pour conclure je dirais deux choses si quand vous faites une recherche avec une petite dose et que vous avez la nausée vous devez changer de crémerie c'est pas normal vous verrez la différence de qualité ici de plus sachez qu'en ce moment il y a des réductions car une partie va être bientôt interdit donc allez-y maintenant vous ne regretterez pas.
