KPV lab tests

275 certificates of analysis for KPV are on file — 269 for single vials and 6 for blends and other forms — from 170 shops and 22 labs. The latest was tested on 29 Sep 2026.

These are certificates shops have chosen to publish, verified for authenticity before listing. Because shops decide which COAs to make public, the set reflects the batches they published rather than every production batch — a selection bias we state openly. What shop COAs show →

Measured amount in amber when it is under 90% or over 130% of the label; Check label when it is under 80% or over 150%. Records without a lot number link as View →. Blend and other-form rows keep their place and page; they are tagged and left out of the figures above, because a blend certificate reports one purity and one amount for the whole vial. Blends with their own page: KLOW lab tests (108)

Seven checks for any KPV certificate

Batch-matched and independent. The certificate names the lot in your hands and comes from a lab the vendor neither owns nor pays.
Purity against the range. Read the figure against what other certificates for this compound report. How to read HPLC and mass-spec results
Mass-spec identity. Only mass spectrometry shows which molecule is in the vial.
Net content, measured. Purity and quantity are separate questions. Why 10 mg isn't 10 mg
Endotoxin on the batch. A missing line means not tested, not passed. Endotoxin testing and LAL interpretation
A lab you can check. Named on the certificate, with a way to verify it. Testing labs we track · Red flags in a certificate of analysis
What no test shows. A clean certificate says nothing about efficacy, dosing or long-term safety.
