Why an independent laboratory matters
A manufacturer tests its own material at release. That is normal, necessary, and the one party with an interest in the answer. What an independent certificate adds, and what it does not.

Every manufacturer worth buying from runs release testing on its own batches. Those figures are usually accurate. The problem is not honesty; it is structure, and an independent laboratory is the answer to it.
Who is asking the question
A release test is run by the party that loses money if the answer is wrong. That does not make it false. It makes it the same category of document as a self-assessment: useful, and not independent, and there is no way to tell the two apart from the outside by reading it.
What an independent assay adds
- It is run by somebody with no stake in the number.
- It is issued under the laboratory's own name and its own certificate number, so the document can be confirmed with the laboratory rather than with the seller.
- It carries the lot number, which is what ties the figures to a specific batch.
- Where a manufacturer's report exists for the same lot, it makes comparison possible, and two laboratories will differ a little for reasons that are not errors.
What an independent assay does not do
It describes the sample the laboratory received. It does not show that every vial in the lot matches that sample, and it says nothing about what happened to the material after the test. Who submitted the sample matters too: a certificate names the party that sent it in, and a sample chosen by a supplier is still a sample chosen by a supplier. How to verify a peptide lab report covers the checks a reader can make.
What this site holds
Each lot in the testing library has a certificate from a named third-party laboratory, on a sample submitted by our supplier. Every certificate page links to the laboratory's own copy and gives the verification number to enter on the laboratory's site, so the document can be checked without going through us. This site does not hold a second report on those lots, from the manufacturer or from anyone else, and does not claim one.
Common questions
Why is a manufacturer's own certificate not enough?
A release test is run by the party that loses money if the answer is wrong. That does not make it false, and such reports are usually accurate. It makes the report useful and not independent, and there is no way to tell the two apart from the outside by reading it.
What does independent third-party testing add to a peptide lot?
A figure from somebody with no stake in it, issued under the laboratory's own name and certificate number, so it can be confirmed with the laboratory directly. It also carries the lot number, which ties the figures to one batch.
What does an independent certificate not prove?
It describes the sample the laboratory received. It does not prove that every vial in the lot matches that sample, and it says nothing about the material after the test. The certificate also names who submitted the sample, which is worth reading.
How can I confirm an independent certificate is real?
Enter the certificate number on the testing laboratory's own verification page and compare the lot number, dates and figures with the copy you were given. Each certificate page on this site gives that number and links to the laboratory's copy.
