What each one tells you, where it stops, and how to check it yourself.
| Document | What it tells you | What it does not tell you | How to check it |
|---|---|---|---|
| Certificate of analysis | A laboratory’s results for one production lot | Anything about a different lot | Scan its QR code, or enter its key, on the laboratory’s own website |
| The laboratory’s name | Who ran the tests | Whether that laboratory is accredited | Find the name on the certificate itself, not only on a store page |
| Accreditation wording | How the laboratory describes its quality system | Anything beyond the exact words used | Read it word for word: accredited to a standard and aligned to one are different claims |
| The list of tests | Which checks were run on that lot | Results for tests that are not listed | Look for identity and purity, then note what else was tested |
| Company details and written terms | Who you are paying, and what it promises if a result disagrees | Anything about whether a product is approved | Look the company up where it says it is registered, and keep a copy of the terms |
A certificate record is short. Each line answers one question, and together they let you check a lot yourself.
As published by Peptara Labs, which describes Titreon Analytical as aligned to ISO/IEC 17025:2017, not itself accredited. This site has not tested this lot. A certificate shows what one lot tested as; it does not show a product is safe or approved for use in people. Source: peptaralabs.io/coa
One production lot, nothing more. A different lot is a different document. As Peptara Labs puts it, a certificate covering a whole product line instead of a batch proves that somebody tested something once.
Identity and purity first. Peptara Labs publishes identity by HPLC and LC-MS, purity against a not-less-than 95.0 percent release criterion, net peptide content, sterility, bacterial endotoxin, heavy metals and a fentanyl immunoassay screen.
No, and that difference is the whole reason to read the wording. Peptara Labs describes Titreon Analytical as aligned to ISO/IEC 17025:2017, not itself accredited. That describes a quality system; it isn't an outside body's finding about one. Read whatever any lab says about itself word for word.
By the batch. Peptara Labs says its vials ship unlabeled, with no lot printed on them, so your order number ties your batch to its paperwork. Its certificates page also has a lookup that finds a record by lot or certificate number.
Who you're paying, and what they owe you if a result disagrees. Peptara Labs LLC is registered in the United States, with a US office at 30 N Gould St Ste 66115, Sheridan, WY 82801, and a day-to-day operations office in Ho Chi Minh City.
Look any company up where it says it's registered, and keep a copy of the terms.
A second lab's test on the same lot, so that batch has two documents instead of one. Where Peptara Labs publishes one, it's a bacterial endotoxin report from Janoshik, which you confirm by entering its printed key at janoshik.com/verify.
Yes, as part of the written terms. Peptara Labs publishes a 60-day money back guarantee, counted from delivery. That gives you the window to have a vial tested elsewhere, with a full refund if it doesn't match its certificate.
When it's published, yes. Peptara Labs' certificates download in full with no account. On 15 September 2026 we opened its Titreon records on titreonanalytical.com using the key printed on each one, and a wrong key stayed locked.
The five documents, as one store publishes them. Each answer links its source. This site has not tested any product.
All five, on its own pages. The certificates, the lab's name and its accreditation wording are on its certificates page. The tests are listed on each certificate. Company details and written terms are on its about and trust pages.

Its list of what comes with an order includes the printed batch certificate for what shipped. The certificates on its certificates page each come from a recent batch.

Scan the certificate's QR code, or type its printed key, at titreonanalytical.com. The record opens with the certificate number, lot and purity, and a wrong key stays locked. A Janoshik report opens from its own QR code on verify.janoshik.com.

Peptara Labs publishes its certificates of analysis, and each one we checked on 15 September 2026 opened on its laboratory’s own website from its QR code or printed key. A certificate shows what one lot tested as; it does not show a product is safe or approved for use in people. See Peptara Labs’ certificates.
