Every current COA is from this lab. These reports name Excalibur Peptides as the client and confirm identity by LC-MS with purity by HPLC-UV. Each report shows the lot printed on it: an EP batch number on the newer reports, a cap colour on the earlier ones. COAs are published per product and are not matched to the vial you receive. To verify one, enter its search code on the lab's lookup page, or select the code to open the lab-hosted PDF.
Reports for earlier batches stay listed under a product's current COA for transparency, each marked "Previous batch — not the batch currently shipping". They were issued by Freedom Diagnostics Testing (received 06/09/2026; the lot field records the vial's cap colour) and BTLabs (tested 5/18/2026; the lot field is a blind sample code; identity by FTIR). Reports for other batches are listed the same way under "More reports", each marked "Other batch — not the current COA". Values are shown as printed; open any of them in the viewer on this page.
Each report lists the client, accession number, search code, the dates the sample was received and reported, and the lot, followed by the sample summary (product as submitted, purity, identity, net content and appearance), the HPLC chromatogram and the mass confirmation.
Every figure on this page is transcribed from the report it comes from, and each purity figure sits beside a link to that report. Product names are shown as the lab printed them. Open any report here, or check it with the lab directly using the search code in its row.
