Certificates are issued per lot.
Each production lot gets its own, issued by an independent laboratory. The one that matters is the one whose number is printed on your vial.
14 published certificates, issued by 4 independent laboratories — published as issued, including the one that missed its label claim.
Published lot certificates.
14 of 14 published lot certificates
Certificates are currently published for 10 of 50 catalog products. For everything else the certificate for your lot is available on request — a compound missing from this table is missing a published record, not a test.
What a certificate covers.
The same six assays on every batch. A certificate that reports fewer than these is answering fewer questions than it appears to.
| Assay | Method |
|---|---|
| Identity | HPLC + mass spec |
| Purity | HPLC |
| Net peptide content | HPLC |
| Heavy metals | ICP-MS |
| Sterility | PCR |
| Endotoxin | USP <85> |
Purity is reported as a measured figure on each lot's certificate. You will not find a purity percentage printed across this site, because a number that is not attached to a lot number is not a result — it is a slogan.
Identity and purity describe chemistry. Heavy metals, sterility and endotoxin describe contamination. Net peptide content describes how much of the powder is peptide at all — the figure most often left off a certificate, and the one that changes what a vial is worth.
Four checks, in order.
Before reading a single result, establish that the document describes the material in front of you.
Does the lot match?
Is the lab named?
Do the dates make sense?
Is there a spec beside each result?
How to get the certificate for a specific batch.
Every order is matched to a tested lot. If yours is not in the archive above, what you send determines whether we can answer.
You already have the order.
Sign in and open your certificates — the exact lots that shipped to you are listed there. If you checked out as a guest, send your order number and we will send the certificate for the lot that shipped to you.
You have the vial but not the paperwork.
Check the archive above for the lot number printed on the vial. If it is not listed, send the compound name and that lot number — the lot number is what makes a certificate request answerable.
You have not ordered yet.
The archive above is public — search it by compound before ordering. For a compound without a published certificate, ask for the one covering the lot currently on the shelf.
Send certificate requests through the contact form, with the compound and the lot number printed on the vial. Every message is stored the moment it is sent.

Questions
Why do only some products have a published certificate?
Publishing lags testing. Every lot is tested before release and its certificate is published per lot; this archive holds the 14 lots published so far, across 10 products. A product missing from the archive was still tested before release — the gap is in what has been published here, not in what was tested — and its certificate is yours on request.
What does “out of specification” mean on a certificate?
It means a measured value fell outside the range the label claims — a purity below the stated figure, or a vial that weighed less than it should. One lot in this archive read out of specification, and it is published anyway with the laboratory's own wording intact. An archive where every result passes is a marketing page, not a record.
How do I check a certificate is genuine?
Each record here carries the issuing laboratory's name and, where the lab provides one, a verification link that resolves on the lab's own system rather than ours. The source PDF is mirrored beside every record so you can read what was issued rather than our transcription of it.
Which laboratories issued these certificates?
4 independent laboratories: AMINO METRICS, FreedomDiagnosticsTesting.com, Pacific Coast Biologics Inc, ILS Laboratories. None of them is Elements DNA. A result issued by the seller is an assertion; a result issued by a laboratory that does not answer to the seller is a measurement. Measured purity across the archive runs 99.01% to 99.99%. No accreditation is claimed for any of them, because none is on file — what is checkable is the name on each certificate.
