Reading an imprint (Impressum) before you order: what should be there

Before you trust a shop with your money, you should know who you’re dealing with. In Germany that question has a legal answer: the Impressum, or imprint. It’s the most boring page on any shop website — and one of the most useful.

Why the imprint matters

German law requires commercial websites to identify their operator. The rules today sit in the Digital Services Act (Digitale-Dienste-Gesetz, §5 DDG), which replaced the old Telemedia Act (TMG) in 2024. Many other EU countries have similar rules. The point is simple: if something goes wrong with an order, you should know which company to contact — and which company you’d hold responsible.

For buyers of research products, the imprint is also a transparency test. A shop that clearly names itself has accepted accountability. A shop that hides behind a contact form and a free email address hasn’t.

What a proper imprint contains

For a company, look for:

• The full company name and legal form — for example GmbH, UG, Ltd, s.r.o.
• A full postal address. A street address where the company can be reached, not just a PO box.
• Who represents the company — usually a managing director (Geschäftsführer) for a GmbH.
• Fast contact options: an email address and a second direct channel, typically a phone number.
• Register details where applicable: the commercial register (Handelsregister) and registration number.
• A VAT ID (USt-IdNr.) if the company has one.

You don’t need to memorise this list. The pattern is what matters: a real imprint names a legal entity, a place and a person, and gives you more than one way to reach them.

Gaps that should make you pause

• No imprint at all, or a link that leads nowhere.
• A name with no legal form — just a brand.
• An address you can’t find, or one that is only a mailbox.
• Email only, especially from a free or anonymous mail service, with no other contact channel.
• A company that doesn’t match the domain or the name on the checkout page or invoice.
• An imprint that changes between visits without explanation.

One of these on its own isn’t proof of anything. Several together are a red flag.

How this shows up on PurityWatch

“Transparency” is one of the five criteria behind every trust score, and the imprint is a large part of it. Our facts sheets have an “Operator / location” row. When a shop doesn’t publish that clearly, we write “not published” — we don’t guess.

Some examples from our watchlist:

• Peptid24 runs peptid24.de. On the product pages we checked, the operator wasn’t clearly named, and contact runs through a ProtonMail address. That’s why transparency is its lowest score. Its low prices — from €24.90, with free EU shipping from €75 — are real advantages; read its imprint before you order anyway.
• Europa-Peptide trades on europa-peptide.de. Our facts sheet lists its operator as not published, so check the imprint on the shop itself — and make sure you’re on the right domain, since look-alikes exist.
• PeptidesDirect is a counter-example: it names its operator, Toptimum Ltd in Cyprus. A named company doesn’t guarantee quality, but it does tell you who to contact.

A two-minute routine

1. Find the imprint. It’s usually linked in the footer as “Impressum”, “Imprint” or “Legal notice”.
2. Write down the company name and legal form.
3. Check the address with a quick map search. Does it look like a business address?
4. Look up the register entry if one is given. A registration number you can’t find is a warning.
5. Compare the company name with the terms (AGB), the checkout page and later the invoice. They should match.
6. Send a short email with a question — for example, asking for the COA of the batch you want. How and how quickly they answer is part of the picture.

The short version

The imprint tells you who is behind a shop. A complete one names a company, an address, a representative and more than one contact channel. Missing pieces don’t prove anything on their own, but they belong on your checklist. On PurityWatch, they show up as “not published” on the facts sheet and as a lower transparency score.
