The paper trail for the first named compound
BPC-157 is one of the two compounds in the nickname, and it's the one with documents Peptara Labs publishes. Here's what's published, what we downloaded, and where one ends and the other begins.

Peptara Labs credits its batch testing to Titreon Analytical, which its pages describe as a third-party laboratory whose quality system is aligned to ISO/IEC 17025:2017, not itself accredited. Janoshik, a separate lab, adds a bacterial endotoxin report on key batches, including the BPC-157 batch but not the TB-500 batch. Both labs are named on the Peptara Labs certificates page.
BPC-157 is the compound whose documents we opened ourselves: a Titreon certificate the vendor names by number, and a Janoshik endotoxin report, both downloaded and file-type checked. Here's what's published and what we only saw linked. See also the name that groups it with TB-500 and the flagship that ties it together. Peptara Labs writes up both compounds on its BPC-157 and TB-500 stack page.
Titreon Analytical, which the live certificates page calls a third-party laboratory whose quality system is aligned to ISO/IEC 17025:2017, not itself accredited. We always keep that qualifier. Without it, a true statement turns false, because aligned to a standard and assessed against it by an outside body are two different claims.
Seven things:
On the published batches, all five heavy metals on the panel, arsenic, cadmium, chromium, mercury and lead, came back Not Detected. A certificate shows what one lot tested as; it does not show a product is safe or approved for use in people.
Each line has limits. HPLC purity is a relative peak area for one lot, not the amount in a vial and not an identity check. LC-MS checks identity by mass: it fits the named compound but can't rule out an isomer or another molecule of the same mass. The fentanyl immunoassay screen flags one target. It isn't a confirmed identification.
COA-2026-8642, a four-page Titreon Analytical panel for BPC-157 batch BPC-260408-A. Both numbers are on a live page, so we can quote them exactly.
Yes, on its /coa page, each from a recent batch. Each certificate records identity, chromatographic purity against a not-less-than 95.0 percent release criterion, net peptide content, sterility, bacterial endotoxin, heavy metals and a fentanyl screen. We opened the BPC-157 certificate and record the rest as published and linked, not read. See the Peptara Labs certificates page.
Yes. A separate lab, Janoshik, adds a bacterial endotoxin report on key batches, including the BPC-157 batch. Those reports have their own numbers, and Peptara Labs publishes a lot-number check that works for any lot on its certificates or reports. We didn't run that check ourselves.
Two BPC-157 files, on 2026-09-01, with file type confirmed: the certificate, a four-page PDF, and the second-laboratory report, a PNG. The certificates page links its certificates and the Janoshik reports for its key batches. Everything beyond those two files we call published and linked, not opened.
One more detail from that page: vials ship unlabeled by design, so nothing is printed on them. The vendor states its route from a vial back to its certificate runs by order number. The thing you can check yourself is the published certificate and its lot-number check.
For the other compound, see the same question asked of the other compound. Our four levels of checking are in what downloaded and confirmed means here.
Everything named here is research-grade material, or a report on one, for readers who open certificates themselves. The supplier we link isn't a medical provider, nothing it sells is an FDA-approved drug, and we never tell anyone what to take or whether to take anything.
Research-grade peptides, listed on its /products page. BPC-157 and TB-500, the two compounds in the nickname, are both there, and CJC-1295 with Ipamorelin is one combined entry. We print no price and make no availability claim. See the Peptara Labs products page.
