Lots on record: 5mg lot LF-01A-2609 (Kovera Labs, tested 10/7/26, 99.481% purity); 10mg lot LF-01B-2609 (Kovera Labs, tested 9/29/26, 99.871% purity); 20mg lot LF-01D-2609 (Kovera Labs, tested 9/29/26, 99.839% purity); 40mg lot LF-01F-2609 (Kovera Labs, tested 10/7/26, 99.829% purity).

Check it yourself

  1. Match the lot number printed on your vial to the lot shown for its size.
  2. Tap "Verify at the lab". It opens the laboratory's own record, not ours.
  3. Compare the figures. If the lab's record and this page ever differ, trust the lab and tell us.

Every certified lot, for every compound, is listed on the certificates page. To order, see the Retatrutide product page.

What each result means

Identity says whether the vial holds Retatrutide at all. The lab measures the molecular mass of the material by mass spectrometry and compares it with the mass Retatrutide should have. A purity figure cannot answer this on its own, because a vial can be almost entirely one substance and still be the wrong one.

Purity is the share of the material that is the target peptide rather than related fragments or leftovers from synthesis, measured by HPLC. Net content is how many milligrams of peptide are actually in the vial. The two are separate measurements, so a lot can test very pure and still read under or over its labeled amount. Both numbers are shown exactly as the certificate states them.

Endotoxin and sterility are separate tests run on newer lots. Where a lot has no result on record, it says "not yet reported" rather than leaving the line out, so a missing test is never mistaken for a passed one.
