What each test measures
Purity (HPLC)
How much of the sample is the declared peptide. Chromatography (HPLC) separates the sample's components; purity is the share that is the peptide. The rest are related substances left over from synthesis.
Measured content
How many milligrams of peptide are in the vial, compared with what the label says. For example, 10.10 mg in a 10 mg vial is 101% of the amount declared.
Blends (GLOW, KLOW)
A vial with several peptides doesn't have a single purity percentage: the lab measures the amount of each ingredient, and that's what we show.
Endotoxins
Fragments of bacterial cell walls that can be left over from manufacturing. The report gives the endotoxin units (EU) in one vial. We publish it for the lots that have this test.
Each result applies to the sample the lab analyzed, not to every vial in the lot.
How to verify a certificate yourself
- Tap “Verify at Janoshik” next to the certificate. The report opens on the lab's website, not ours.
- Check that the report number, the lot and the results match the ones on this page and on the product page.
- If a certificate has no link, use the key printed at the bottom of the report on Janoshik's website. Questions? Email us at info@kailab.com.co.
What we publish and what we don't
- We only publish a certificate if its lot number matches the vials we ship.
- A report without a lot number, or from another lot, doesn't go on the page.
- When the lot changes, we change the certificate.
