Every Certificate Peptara Labs Publishes, Counted

What is published, counted

Peptara Labs lists sixteen research-grade SKUs on its products page. Fourteen carry a published certificate. Two read Pending, with a certificate in testing and available on request: Epithalon and Glutathione.

The catalog names, set down as names only, with no claim here about the current availability of any one of them:

• Retatrutide, Tirzepatide, BPC-157, TB-500, GHK-Cu, CJC-1295 with Ipamorelin
• KLOW, MOTS-c, Tesamorelin, MT-2, Semax, Selank
• SLU-PP-332, PT-141, Glutathione, Epithalon

What each certificate covers

The source is a panel, so it is set down here as a panel. Each certificate confirms:

• identity, by HPLC retention-time matching and LC-MS;
• chromatographic purity by HPLC, against a release criterion of not less than 95.0 percent;
• net peptide content;
• sterility;
• bacterial endotoxin;
• heavy metals;
• a fentanyl immunoassay screen.

The heavy metal panel covers arsenic, cadmium, chromium, mercury and lead. All returned Not Detected on the published batches.

Measured purity across the current published catalog runs 98.6 to 99.6 percent. The homepage rounds that range to a stated 99% average purity. The testing laboratory is Titreon Analytical, described on the live page as a third-party laboratory whose quality system is aligned to ISO/IEC 17025:2017, not itself accredited.

The five files we opened

Fourteen certificate PDFs and four second-laboratory reports are published and linked from the certificates page. This site downloaded five of them and confirmed their file type. The files beyond these five were not opened by this site.

One certificate named in full

Peptara Labs names one certificate in full on its verification guide: COA-2026-8642, described as a four-page Titreon Analytical panel for BPC-157 batch BPC-260408-A. The number and the batch code are published by Peptara Labs on a live page, so they are quoted here. Peptara Labs sets them out on its verification guide.

The route from vial to certificate

Vials ship unlabeled by design. No lot is printed on the vial. The published route to tie a batch to its certificate is to message support with the order number.

Published batch identifiers do exist per SKU on the certificate pages. The retatrutide card shows a batch code and a June 2026 test date. The second laboratory is set out in the laboratories that signed them. The two Pending records are listed in the two records that say Pending. The one-pass summary is the summary file.
