Nothing Here Rests on Our Word

Which is fortunate, because you have no reason to take it. This page explains what this site is, how it is written, and the test to run on it before you believe any of it.

KnownBatch is a reading desk. It reads what peptide sellers publish about themselves and writes down what the documents actually say.

What this is

A reading desk, not a shop and not a laboratory

This market has a strange gap in it. Almost everything written about buying research peptides was written by somebody selling them. Search for how to read a certificate of analysis and seven of the first nine results are the education section of a shop. The advice is often correct. It is also, without exception, written by a party with a position.

This site is twenty one pages and about forty thousand words covering the same ground from the other side. Seven checks to run before paying anyone. Thirteen rows to fill in. How to read a lab report field by field, what the fields mean when they are missing, and what the whole document still cannot tell you.

The one structural difference

We do link to a seller and we are paid when you buy from them, which is stated in full on the disclosure page including the cookie name and the length of the window. What we do not do is hold stock, take payments, or have a product whose shortcomings a page might quietly route around.

The method

We open the document, and we say which one

There is no original research on this site and no testing. We have never commissioned a laboratory analysis and could not afford to run the ones we write about, which start at 215 dollars for a single vial.

What happens instead is unglamorous. Somebody opens what a seller published, reads it against the seller's own marketing, and writes down where the two disagree.

  1. Twenty sellers were probed for whether they publish certificates at all. Eight do.
  2. Four of those libraries were opened and read properly rather than counted.
  3. Nine certificate files were downloaded and kept, so a figure quoted here can be checked against the file it came from rather than against our summary of it.
  4. Two laboratories are named on this site, Janoshik Analytical and Bioviridian, because those are the two that appear on the documents. Neither has any relationship with us.
  5. Where a report carries a verification key, it was typed into the laboratory's own page to see whether the document the seller published matches the record the laboratory holds.

Every figure on this site names where it came from. Most sections carry a line under the heading naming the specific document, batch or task number behind that section, which is there so a claim can be traced rather than trusted.

What happens when it does not work

One check on this site could not be completed. The laboratory's verification page returned a firewall block, so that page says so in the text rather than implying a result we did not get.

That is the standard. Where something could not be verified, the page carrying it says so, because a site arguing that unverifiable claims are worthless does not get to publish one.

Who writes it

One person, and no credential worth citing

This is written by one person, not a company, not a team and not a board. There is no medical advisor, no scientific committee and no panel of reviewers.

We say that plainly because the alternative is common in this category and it is worse. Sites in this market advertise medical advisory boards with no named members on them. A credential that cannot be checked is the exact failure this whole site is about, and putting a decorative one at the top of this page would end the argument before it started.

So there is no qualification being claimed here. No chemistry degree, no clinical training, nothing that would let you defer to us instead of checking.

The test, and it is the same one we apply to sellers

Delete our name from every claim on every page of this site and see what is left standing. It should be a laboratory's name, a batch code, a task number and a verification key, none of which we control and all of which you can check on somebody else's server.

If deleting our name takes the evidence with it, we have not earned anything, and you should treat this site exactly as sceptically as the pages it criticises.

That is also the answer to the obvious question about why a name is not printed here. It is not modesty and it is not mystery. It is that a name would be the one piece of this site you could not check, and adding an unverifiable thing to a page arguing against unverifiable things would be a poor trade. If ever there is something on this site that only works because you believe a person, that will be the thing to delete.

The limits

What this site cannot do for you

It cannot tell you a compound is safe. A laboratory report describes what is in a vial. It says nothing about what happens next, and no seller and no site can honestly tell you that.

It cannot tell you the vial you receive is the one on the certificate. A document proves that a laboratory holds a record and that the paperwork is consistent. The parcel is still trust.

It cannot keep up with a market that moves weekly. Every figure here carries a date. A price list changes, a certificate library grows, a seller fixes something. If a date on a page is old, treat the figure as old.

And it is not neutral. We are paid by one of the sellers named here, which is why the thirteen rows run against that seller too, and why two of the thirteen are rows they do not currently pass.

Corrections

If something here is wrong, it should be said so

Figures on this site have been wrong and corrected. A count was restated when the research behind it could not be produced. A claim about a seller was softened when their own document turned out to be better than the page around it suggested.

Every figure names its source precisely so that it can be argued with. If you find one that does not hold, write and it gets fixed or removed, and the page says what changed.

Write to us

Corrections, a seller we should have checked, or a document that contradicts something here. All three are useful and the third one most of all.
