One record, shown in full
Klow matches one published Peptara Labs lot, and no other row on that list.
Behind it is one lab panel, read on the certificate index on 2026-09-01. Here it is in full.
Resolved 2026-09-07. We read the lot row on the supplier front page on 2026-09-07, and the panel lines on the certificate index on 2026-09-01.
The klow name matches one published lot, and no other row: lot KLW-260412-A, certificate COA-2026-8537, tested June 2026. A certificate shows what one lot tested as; it does not show a product is safe or approved for use in people. Below is that certificate record, line by line, and what it can't tell you: what's in the entry, any research, or a second-lab report. See also why the literature column stays unfilled and what a filled cell had to survive.

Lot KLW-260412-A, HPLC purity 98.60 percent, certificate COA-2026-8537, tested June 2026, on a panel run by 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. Read from the supplier front page, read on 2026-09-07. The vial is sold as the KLOW combo vial at Peptara Labs.
Our rule, plainly: a purity figure only appears next to its own lot and certificate number. We never average it into a brand number or quote it for an unlisted lot. Only this entry's row is shown here.
A set of named lines. We list them to show the name matches a real document, not to explain each method. We read every line on the certificate index, read 2026-09-01.
| Line as the panel names it | What it establishes | What it does not establish | Where it was read |
|---|---|---|---|
| Identity by HPLC retention time | A matching retention time, read as an identity call. | Not the second identity method, and not purity. | Certificate index, 2026-09-01 |
| Identity by LC-MS | A second identity call, by mass spectrometry. | Identity, not how much of the lot is the named material. | Certificate index, 2026-09-01 |
| Chromatographic purity, HPLC | Purity read on HPLC against a release criterion of not less than 95.0 percent. | A threshold, not a measured figure for any other lot. | Certificate index, 2026-09-01 |
| Net peptide content | A named line on the panel. | No figure is attached to it here. The line is named, the number is not. | Certificate index, 2026-09-01 |
| Sterility | A named sterility line. | The batch tested, not a container in a reader's hands. | Certificate index, 2026-09-01 |
| Bacterial endotoxin | A named endotoxin line. | Not the second-laboratory endotoxin report, which does not cover this entry. | Certificate index, 2026-09-01 |
| Heavy metals panel | Arsenic, cadmium, chromium, mercury and lead, each Not Detected on the published batches. | A panel result, not a claim about another lot. | Certificate index, 2026-09-01 |
| Fentanyl immunoassay screen | A screen that closes the panel. | A screen, and nothing past it. | Certificate index, 2026-09-01 |
The lab, with its qualifier as always: 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.
A panel shows what it measured, for the batch it names, on the day it was issued. It doesn't tell you what's in the entry, and we don't state that: none of our sources records it, and our one-name rule bars naming other entries anyway.
A certificate isn't research either. It records one lot by named methods. None of our sources includes a literature search for this name, so that column says not searched. See why the literature column stays unfilled.
Two more gaps. Net peptide content is a named line with no figure here, because we didn't download a panel file for this entry. And no second-lab endotoxin report covers it: key batches carry an independent bacterial endotoxin report from Janoshik, and none is this one. See what a filled cell had to survive.
Both names, side by side: back to the resolution table.
We match names to records. We report what a record says, when we read it, and where a lookup came back empty. We say nothing about how any material behaves, in anyone, anywhere. The entry named here is sold for research and carries no approved human use. Nothing on this site is medical advice or an instruction, and we never ask you to do anything.
On the supplier front page, read 2026-09-07, the lot is KLW-260412-A with an HPLC purity of 98.60 percent and certificate COA-2026-8537. The figure only appears with that lot and certificate number.
In order: identity by HPLC retention time, a second identity check by LC-MS, chromatographic purity on HPLC against a release criterion of not less than 95.0 percent, net peptide content (named, no figure here), sterility, bacterial endotoxin, a heavy metals panel reading Not Detected for arsenic, cadmium, chromium, mercury and lead, and a fentanyl immunoassay screen.
No. Key batches in the catalogue carry an independent bacterial endotoxin report from Janoshik, but none covers this entry. The panel's own endotoxin line is the only one for this name.
