Every comparison table on a shop's website was filled in by one of the two companies in it. This one has thirteen rows, one column filled in from a published certificate and a seller's own terms. The other column is empty, and it is for the site you already have open.

One column filled from a published certificate
You have two tabs open, and both of them say the same four things.
Third party tested. Highest purity. Fast shipping across Europe. Trusted by thousands.
Read the two homepages side by side and you will find those promises in almost the same words. That is not a scandal. It is what a category sounds like once everyone has read everyone else's website. It also leaves you exactly where you started. Two shops, one card, and no way to tell them apart from the outside.
So here is the part nobody says out loud. Every comparison table you have seen on a shop's website was filled in by one of the two companies in it. The winning column was written by the winner. So was the losing column.
We are not going to do that. Partly because it would be dishonest, and partly for a duller reason: we do not know which site you have open. We have never seen it.
So we filled one in and left yours empty.
Three reasons, and the third is the one that matters.
The first is the one above. A shop's comparison table is a document about the shop that wrote it, and the losing column is fiction by construction.
The second is that German law is stricter than most readers expect about what a seller may say about a named rival. We would rather tell you that than pretend the restraint is generosity.
The third is simply that we do not know your other tab, so any value we typed into that column would be a guess dressed as a fact.
We chose the rows, and we are not neutral about where you go next. Those are the only two things left that we could tilt, so hold them against us while you read.
Which is why the same thirteen rows run against every seller here, including the one we link to. Every value in every filled column is one you can go and check yourself, on a page or on a laboratory's server. If a row could not be checked, it is not in the table.
Keep the other tab open. Fill your column in as you go.
Janoshik / Task #163572 / RT6423CP
These six separate a picture of a certificate from a record at a laboratory.
| The check | One seller's answers, in full | The site you have open |
|---|---|---|
| 01Which laboratory is named on the report itself, not in the banner? | Janoshik | for you to fill in |
| 02Is there a batch code on the page, before you pay? | RT6423CP | for you to fill in |
| 03What is the laboratory's own reference number for the test? | Task #163572 | for you to fill in |
| 04Is there a verification key, and an address to type it into? | THC88ILYEN8S, at janoshik.com/verify/ | for you to fill in |
| 05Whose name does the laboratory have in the client field on its own page? | Crystal Peptides EU | for you to fill in |
| 06Which result lines does the report actually carry? | Amount and purity, each with a figure against it | for you to fill in |
An empty cell here is not a claim about the other seller. It is a space for you to write in.
Row four is the one worth actually doing. Type the Crystal Peptides key at janoshik.com/verify/ and what loads is the laboratory's page, not the seller's. Same task number, same batch, and a client field reading Crystal Peptides EU. Type the American Peptides code at bioviridians.com/coa-search.html and a different laboratory does the same thing.
That is the difference between a document a seller shows you and a record a seller cannot reach. We typed both keys ourselves on 11 September 2026 before publishing this page.
Twenty sellers / September 2026
You are going to reach a row you cannot fill in. Probably several. Here is what that means, and what it does not.
It does not mean the seller is a fraud. Plenty of honest shops have never published a task number, because almost nobody has ever asked them for one. An empty box is not evidence about them.
It is evidence about you. It tells you what you would be buying on. Not on a document. On the seller's word, or on the word of whoever sent you. That can still be a fine decision. People make it every day and most of them get their parcel. You just now know which kind of decision you are making, which is more than you knew four minutes ago.
The row has to be fillable before you pay. A certificate that turns up after you email and ask is a real certificate, and it is also a certificate on the seller's timing rather than yours. Write that row blank and put a note beside it.
It is also the fastest check there is. Of twenty sellers we probed in September 2026, twelve had no public certificate page at all, and you find that out in about ten seconds.
And if you can fill a row in, that is a good sign about them, not a bad one about us. If the site in your other tab names its laboratory, prints a batch, and gives you a key that works, you have found a seller worth reading. That is the point of the exercise. It was never to make us win.
Crystal Peptides / 13 May 2026
These four come off the document rather than off the marketing.
| The check | One seller's answers, in full | The site you have open |
|---|---|---|
| 07What was the laboratory asked to do, in its own wording? | “Common GLP-1 peptide blind test (Semaglutide, Tirzepatide and Retatrutide)” | for you to fill in |
| 08What dates are on the record? | Ordered 13 May 2026. Sample received 18 May. Analysed 25 May. | for you to fill in |
| 09Are both numbers in the results box shown, not just the percentage? | 22.43 mg against a 20 mg label. Purity 99.744%. | for you to fill in |
| 10Does the headline purity number on the site match the figure on the certificate? | Site says over 99%. Report says 99.744%. Consistent. | for you to fill in |
Row seven is the one most people have never heard of. Tests requested is a field on the report, filled in by the laboratory, describing what it was asked to do. Crystal Peptides' says blind test, which means the lab was not told what the sample was and had to identify it. American Peptides' does not: it lists the methods the laboratory ran, which is a different and weaker thing. A seller cannot write either line. Only the lab can.
Row eight is smaller and stranger. There are three dates on this record, twelve days apart, and they are days apart, because a sample was posted and took time to arrive. Nobody forging a document invents a shipping delay.
Every shop looks the same on the good day. These three are about the other one.
| The check | One seller's answers, in full | The site you have open |
|---|---|---|
| 11Is the report on the page itself, with no email required to get it? | Yes. A public library, 109 files. | for you to fill in |
| 12What does the delivery page say about your country? | EU dispatch. Free standard over €200. Customs seizure is named in the terms. | for you to fill in |
| 13What do the published terms say when it goes wrong? | Seven days to report a wrong, missing or damaged item, and only a full continuous unboxing video is accepted as proof. One free replacement for confirmed non-delivery or seizure, a refund if that also fails, and no second replacement. | for you to fill in |
Row twelve is worth reading twice, and not for the speed. Look at whether the seller's own delivery table puts a customs step in front of your country. If it does, the parcel you are about to buy crosses a border where somebody who is neither you nor the seller decides what happens to it.
Row thirteen is the seller's own wording in full, including the parts that are against them. Seven days to report a problem, a continuous unboxing video as the only proof accepted, one free replacement and no second one. They publish it, and it is printed here rather than left for you to find at the bottom of a terms page.
Read that answer and you will notice it is not generous. The reason it is worth printing anyway is that a seller who will not tell you the limits before you pay is telling you something about the limits.
This form is narrow on purpose, and it is worth being clear about what it leaves open.
Start with row four, because it is the only one that takes you off this website and onto somebody else's. Then take the form to the tab you already had open.
Every seller looks the same on the good day. Four things decide what happens on the bad one, and all four are published before you order if you go and read them.
Read the seller's own published pages, not their marketing, and none of these terms were written by us.
We will send the form as one page, one column filled in from a published certificate and the other ruled and empty, so you can run it on any seller in any country.
You are on the list.
The thirteen-row form comes by email, as one page you can print.
