Every Kisspeptin vial against its label
One dot per vial, placed by how much it held compared with the amount on the label. 89% held more than the label and 11% held less. The ones to worry about sit on the left.
Dot chart of 27 vials (every Kisspeptin vial on file), each placed by its measured amount compared with the label, from 50% under to 50% over. 7 are within 5% of the label, 20 are 5 to 20% under or more than 5% over, 0 are more than 20% under, 0 are more than 50% over, and 0 were empty.
What an honest Kisspeptin lab report should show
Use this list on the report a vendor sends you, before you trust the numbers on it. How to read a COA
- Lot match. The lot or batch number on the report matches the one printed on your vial.
- Named, independent lab. The report names a lab you can contact and check it with. A PDF with only the vendor's logo doesn't count.
- HPLC and mass spec. HPLC measures purity and mass spectrometry confirms identity. You need both.
- Recent, batch-dated test. The test is dated for this batch, not one report reused for years.
- Purity isn't identity. A high purity figure says nothing about what the compound is unless the mass spec result matches it.
- Contaminants. Endotoxin, heavy metals and sterility results, where the lab offers them. Most reports leave these out.

Kisspeptin: common questions
Which Kisspeptin vendors pass lab testing?
No vendor has 5 or more independent lab reports for Kisspeptin yet, so none is ranked. The table on this page lists every vendor's results so far.
How often do Kisspeptin vials fail testing?
0 of 27 Kisspeptin 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 Kisspeptin vials underdosed?
Usually not; if anything they run over. The typical Kisspeptin vial on file held +8.2% 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 Kisspeptin vials test at?
The median Kisspeptin vial tested at 99.66% 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 Kisspeptin results come from?
From 14 independent lab reports, mostly commissioned by buyers, covering 27 vials from 6 vendors, dated Aug 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 Kisspeptin?
No. VendorVerify doesn't sell peptides of any kind. Vendors can't pay to change their score, rank or warnings. No affiliate links, no coupon codes, no paid rankings.
