How do I check Tesamorelin (Premium Research Peptides)'s certificate myself?
Find the certificate on tesamorelin.co.uk and read four things: an independent laboratory is named; the client field names Tesamorelin (Premium Research Peptides), not a supplier; the compound line names the peptide you are buying, not only a batch code; and the report opens on the laboratory's own website from its task number and key (verify.janoshik.com for Janoshik). Then compare the batch number on the report with the one on your vial. The free COA Checker on this site runs the first three checks on a photo of the certificate.
