Batch record

KLOW 80 80 mg

What this record shows — two layers. (1) An analytical report supplied with the lot by the manufacturer (purity, sterility, endotoxins, heavy metals). (2) Independent third-party verification commissioned by VP Peptides from Sonic Laboratories (Ohio, USA), analyzed by LC-MS/MS and verifiable by code on the laboratory’s own site. Each layer is shown separately below; a parameter not in a given document is marked NOT TESTED or PENDING, never inherited from the other certificate.

Analytical documentation supplied with the lot by the manufacturer — reference PEP2608NP008, reported 2026-08-01. These figures come from the supplier’s own certificate; they are not independently verified by VP Peptides. The supplier document is retained on file and available on request; where the certificate does not state a method, the method is shown as not stated rather than assumed.

Parameters marked NOT TESTED are not part of this chemistry report (Sonic reports identity, purity, content, impurities and residual solvents by LC-MS/MS). Sterility, endotoxins and the elemental panel require a separate microbiological/ICP-MS report.

Provenance timeline

One tested vial ≠ the whole batch. A laboratory result characterizes the sample tested. Full batch assurance also involves multi-vial sampling, content uniformity and stability monitoring. We show this openly rather than imply one test covers every vial.

About this compound

Research use only. This batch record is analytical documentation for laboratory research material. VP Peptides products are not drugs, foods, or cosmetics; not for human or veterinary use, diagnosis, treatment, or administration. Nothing here is a claim of safety or efficacy. A verified parameter describes the tested material only.
