Verification questions
Where is the lot number on my vial?
The lot number is printed on the vial label, next to the QR code. Scanning the QR code opens this page with the lot already filled in.
What does a verified lot tell me?
It confirms the lot is on record with Puritide Research. You also see the batch purity, the lab that ran the test, and the test date. Every batch is tested by analytical HPLC and mass spectrometry.
What if my lot number does not verify?
First check the characters on the label, since the letter O and the number 0 are easy to mix up. If it still does not match, email support@puritideresearch.com with a photo of the vial and we will look into it.
Where can I see every certificate of analysis?
All posted certificates are listed on the certificates of analysis page at puritideresearch.com/certificates.
