Part of the GLP range is sold under store names, and each product page carries a Bioviridian certificate for Peak Lab Peptides whose identity row names the compound: GLP-1 S is semaglutide, GLP-1 T is tirzepatide and GLP-3 is retatrutide. GLP-1 C is cagrilintide, on a certificate for sample “GLP-1 CAG 10mg” whose identity result is Cagrilintide, and the page of GLP-1 C + GLP-1 S, the blend of the two, carries both the cagrilintide and the semaglutide certificates.

Testing: Labs & Certificates of Analysis
Peak Lab Peptides publishes a certificate library of 48 reports, each naming Bioviridian as the laboratory and HPLC + MS as the method, with the purity, the lot and a pass result. On September 24, 2026 Prof. Peptide read one in full, BPC 157 10mg (COA6663, lot BC-202607-001): identity confirmed by LC-MS/MS, content 10.65 mg and purity 99.7% by RP-HPLC at 214 nm. The same certificate, fetched from Bioviridian's own host, matched it field for field.
On October 11, 2026 Prof. Peptide looked up certificates from the library and found each one at Bioviridian's own file store, with the code, vendor, sample name, purity, content and issue date agreeing. The sample-received date on Peak Lab's copies differs from the laboratory's on all three, so the panel below counts none of them as matched.
