Batch registry

Batch verification — documented, and what wasn’t.

Most suppliers publish a purity number. We publish the whole picture: which tests a batch actually passed, which were not run, who produced the report, and whether VP commissioned it. Below is the current registry.

Three levels of documentation

Not all “lab tested” claims mean the same thing. We label every result by where it comes from:

Supplier batch documentation

Analytical data generated or commissioned by the manufacturer of the material.

Third-party lab report

A report from an independent U.S. laboratory (Sonic Laboratories, Ohio), verifiable by code on the lab’s own site.

VP independent verification

Analysis that VP Peptides itself commissions from an independent laboratory. FULFILLED for the three verified batches below (Sonic Laboratories); PENDING for the rest.

Every parameter carries a status

VERIFIED a documented result exists  ·  NOT TESTED not part of the report  ·  PENDING commissioned, result not in yet. An empty field is never left to imply testing happened.

The three verified batches carry an independent Sonic Laboratories report (Ohio, USA · LC-MS/MS): identity purity net peptide content related substances residual solvents all VERIFIED. Sterility, endotoxins and heavy-metal / elemental panels are NOT TESTED in these chemistry reports. Remaining catalog items carry supplier batch documentation and show VP independent verification pending until a VP-commissioned report is on file.

One tested vial ≠ the whole batch. A report characterizes the sample that was tested. Full batch assurance also involves multi-vial sampling, content uniformity and stability monitoring. We say so rather than imply a single test covers every vial.

Research use only. This registry is analytical documentation for laboratory research materials. 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.
