How to verify a certificate

  1. Find the lot number on your vial. It is printed on the label, for example KB55627.
  2. Look it up. Enter it at buyselankpeptide.com/verify, or open the matching lot in the COA archive.
  3. Check the lab's own record. Scan the Freedom Diagnostics QR code printed on the certificate, then search for klow.bio under the Company tab to view the laboratory record.
  4. Compare the details. Lot number, the laboratory’s reference numbers, purity and dates should match exactly.

What a certificate of analysis does and doesn't show

  • A COA reports the identity, purity and content of the specific sample tested, on its test date. Results apply to that lot only.
  • HPLC purity measures the main peak relative to other detected components. It does not identify the peak on its own; the separate identity test (LC-MS) does that.
  • Mass confirmation matches molecular weight. It does not by itself confirm amino-acid order.
  • Endotoxin and microbial results apply only where those tests appear on the certificate. Lots without them are marked "Not tested".
  • A certificate does not establish stability after the test date or suitability for any particular purpose.
