Verified order

Arrived next morning, sealed and cold

Ordered just before the afternoon cut-off and the box was on the bench the next morning. Vials sealed, lyophilised cake intact, CoA in the envelope with a matching batch number.

🇳🇱Joost B.
Verified order

Support actually answers technical questions

I asked about storage after reconstitution and got a proper answer with a reference, not a copy-paste reply. That is rare in this space.

🇳🇱Aylin K.
Verified order

Batch numbers match the published reports

Cross-checked the batch on my vial against the lab results page before opening it. Same number, same date, same purity figure. Exactly what I want to see.

🇧🇪Mathieu D.
Verified order

Good products, packaging could be smaller

No complaints about the compounds or the speed. The outer box is larger than it needs to be for two vials, which made the parcel awkward for my post point.

🇳🇱Sanne V.
Verified order

Replaced a courier-damaged parcel without argument

One vial arrived cracked after a rough courier handover. Sent a photo in the evening, replacement shipped the following morning at no cost.

🇩🇪Lukas H.
Verified order

Discreet and consistent across six orders

Sixth order this year. Same labelling, same fill weights, same paperwork every time. Consistency is the whole point for repeat work.

🇳🇱Elif Y.
Verified order

The reconstitution calculator saved me time

Used the on-site calculator to work out concentrations before the shipment arrived. Small thing, but it removed a step from my prep.

🇧🇪Pieter M.
Verified order

Fast within the EU, customs added a few days

Shipping into France took a day longer than quoted because of a customs check. Tracking stayed accurate throughout, so I knew where it sat.

🇫🇷Nadia S.
Verified order

Clear labelling, no guesswork

Every vial carries the compound, the fill weight, the batch and the best-before date. I no longer keep a separate spreadsheet to track what is what.

🇳🇱Rob T.
Verified order

Wholesale terms were straightforward

Set up a recurring institutional order through the bulk desk. Pricing tiers were explained up front and the invoice matched the quote exactly.

🇩🇪Ingrid W.
Verified order

Great service, one item was back-ordered

Three of four items shipped immediately; the fourth was out of stock and I was not told until I chased it. The refund was processed quickly once I did.

🇳🇱Casper L.
Verified order

Purity figures hold up under our own HPLC

We ran an incoming-goods check on two batches against our own column. Both came back within a tenth of a percent of the published certificate.
