Professor.nl 

Communicates very well and are very discreet

Four Days After Sending My Payment I Have Been Told "We Havent Recieved Or Noticed Your Payment Yet"
Which is very frustrating cause its been 340euro Thrown away, i still hope this gets resolved so i can make this a 5star review bcz last time i ordered it was very worth it.

Edit:
Shipment arrived, and everything is perfect.
Cant recommend Professor.nl enough

I think The product is mostly inactive isomers (erythro) because I needed to dose 42mg (of wich 28 intranasal) for it to have any effect on my heart rate. I can't say forsure, but its definitely not the one you can dose 10mg and feel it like people report feeling real 4f mph. But there's another big problem: IT GAVE ME AN IMMUNE REACTION!!! God knows what impurities/contaminants they put in there, I got spots on my skin that itch. I only used 3 times.

Really over the Top!
Selection is more than good and first test is running well. My plats are very satisfied and a little bit tired now, so i will fetch them to bed✨
Will be back soon, there's no need to search any longer👍🏻 Looking forward to test the other products, but atm i'm very Happy.

Even a small gift was included, THX!
Greetings to the complete Team✌🏻

Fast shipping but medium-low quality products, even though the website indicates >90% purity. Good costumer service.

Well first I was scared because I never got an email from DHL to track my parcel, but thats not the fault of proffessor. It still arrived 2 days after they got my money.

Top quality
Top client service

10/10 would recommend

Guys are legit. Nice website, wide variety, free samples and gifts with each orders, reward points and good communication. Too bad a-pihp was banned tho.

Had a few problems in the past few orders, but the team helped me out and resolved all issues. Sometimes it takes a while, but if you’re patient they will get it all right. Thank you.

3 weeks package was never sent. A refund was requested and I was told I would receive one but radio silence since. Do not order

Ok I am skeptical guy
I don't trust the internet in general
But I have put 5 orders in 5 weeks and they have all come through exactly what I wanted plus a few bonus
This is the best for me yet

I've been a client of Professor.nl since the very start – I was actually one of his first clients, interestingly. I even met him in person, as he came and delivered it to me personally.

Unfortunately, however, much has changed since then. I would be VERY cautious with ordering from him now. Please test and make sure you are getting what you ordered.

– Product purity is highly questionable. I ordered IPPH (Isopropylphenidate), which he says is > 97% pure. But on the box, it clearly says "FLUOR" (fluoride), which clearly should not be in IPPH. This would then be 4F-MPH.

– Product itself comes from another vendor whom is untraceable. Website does not work, no registration whatsoever. Very sketchy.

– When asking for clarification and for answers, the Professor simply reads the message, and never gets back to you. No comment whatsoever.

Highly disappointing. Please be cautious with this, I would avoid these days.

Products quality sucks. Every product product for an a total amount of 200€ was 85% useless and extremely underwhelming.

Don’t purchase from them.

Immediate response.
Professionals.

I highly recommend high level

great service, quality products.

the customer service is fantastic

Still the best website on the net, large variety of products and the average delivery time is 2-3 days to france.

Paid on the 26th, received the 30th ( long bc blank days holidays)

Go for it! no scams and see you in a few days for my 4th order!

Final edit: changing this to 5 stars as I sent the prof a letter showing my parcel was seized and within 2 mins i got a full reimbursement including shipping costs.

Edit: about the below, the professor has responded and is looking into getting things sorted and given I've had many orders with them before should all be good.👌👌 when it gets sorted I'll update this again but looking good.

Exit scam? Parcel didnt arrive, even though I got an email saying it did. Sent two emails asking for an explanation and normally where they respond very quickly, radio silence. So I'm not sure wth is going on, perhaps just be careful. Will update if things get sorted.

Excellent supplier of life-changing tryptamines.
Many people can benefit getting rid of addictions and improving intelligence, cognitive capabilities and achieve new levels of spiritual exploration thanks to the products sold by Professor.nl
