Every KPV vial against its label
One dot per vial, placed by how much it held compared with the amount on the label.
Dot chart of 22 vials (every KPV vial on file), each placed by its measured amount compared with the label, from 50% under to 50% over. 4 are within 5% of the label, 18 are 5 to 20% under or more than 5% over, 0 are more than 20% under or more than 50% over, and 0 were empty.
KPV: common questions
Which KPV vendors pass lab testing?
No vendor has 5 or more lab reports for KPV yet, so none is ranked. The table on this page lists every vendor's results so far.
How often do KPV vials fail testing?
0 of 23 KPV vials on file failed (0.0%). A vial fails if it's empty, under 95% pure, more than 20% under its label, or more than 50% over it.
Are KPV vials underdosed?
Usually not; if anything they run over. The typical KPV vial on file held +13.7% compared with the amount on its label. Individual vials vary much more than that, and the chart on this page shows every one.
What purity do KPV vials test at?
The median KPV vial tested at 99.75% purity. We count anything under 95% as a failed vial and give full marks for purity at 99.5% or higher, because small differences above that are within normal lab-to-lab variation.
Where do these KPV results come from?
From 15 independent lab reports, mostly commissioned by buyers, covering 23 vials from 12 vendors, dated Apr 2025 to Sep 2026. VendorVerify doesn't test anything itself. A report a vendor paid for is only used if the lab can verify it, and it is marked as vendor-commissioned and counts at half weight.
Does VendorVerify sell KPV?
No. VendorVerify doesn't sell peptides of any kind. VendorVerify sells nothing and takes no money from vendors. No affiliate links, no coupon codes, no paid rankings.
