Ordered on a Tuesday, the parcel was in Munich by Thursday. Tracking worked the whole way.
Plain box, correct invoice, no drama at customs. Exactly what it should be.
Asked a question about storage conditions before ordering and got a plain, sourced answer the same day — not a sales pitch.
Fast dispatch to Vienna, and the bundle price matched the arithmetic on the product pages to the cent.
Second order. Same packaging, same turnaround, same paperwork. Consistency is the review.
I compared five EU storefronts for documentation before ordering. This was the only one where every identity figure carried a source and a date. That decided it.
Emailed to change the delivery address an hour after ordering. Fixed within the afternoon, confirmed in writing.
Stock levels on the site were accurate; nothing on my order went missing or on backorder after payment.
Their FAQ answered the payment and shipping questions honestly enough that I did not need to contact support at all.
Parcel to rural Ireland in five business days, tracked the whole way. No complaints.
The specification page listed the CAS number, sequence and mass with sources and dates before I asked. That is the level of documentation I wish every vendor treated as normal.
The concentration calculator with the printable per-graduation table saved me a spreadsheet. Small thing, kept me on the site.
Vials arrived exactly as photographed, labels legible, batch details on the paperwork. Reordering was two clicks.
What convinced me was the quality page saying plainly what they do and do not publish. No inflated promises, just the record. The order itself was uneventful in the best way.
The listing said 2–5 business days to Spain and it was four. Tracked door to door.
Checkout was clear about VAT and shipping before the payment step, not after. Appreciated.
The vials match the catalogue photography exactly — same label, same format. Sounds trivial until you have received enough parcels where it does not.
Straightforward. Ordered two reagents, both arrived within the stated window, sealed and cold to the touch, paperwork complete.
The restriction notes on the product pages are unusually direct for this category. I would rather buy from a shop that states them than one that hides them.
Every question I had before ordering was already answered somewhere on the site — the spec table, the quality page, the FAQ. The order matched the listing exactly. That is the entire job, done properly.

What an HPLC purity figure measures
A purity percentage is a ratio of peak areas from one chromatographic run. What the figure covers, what it leaves out, and what to read beside it.
Four figures that identify a peptide
CAS number, sequence, molecular formula and molecular mass. What each one states, how the four check one another, and where to verify them yourself.
