LA Peptides rebuilt its storefront in early October 2026. Every page, including product pages and prices, now opens only after a free members sign-up that asks visitors to confirm they are 21 or older and buying for research use. The pricing board compares 57 offers from LA Peptides’ catalog. In PeptideBenchmark’s certificate record, last reviewed October 6, 2026, 134 of 153 certificate-to-product relationships were verified at the issuing laboratory; the record also keeps entries from LA Peptides’ previous site, which no longer serves them. Reported purity averages about 99.7%.
Readers with a free LA Peptides members account who want to check their own lot: find the lot’s certificate in the COA portal, then confirm its printed code at Bioviridian or Freedom Diagnostics.
A reader needs a free LA Peptides account to confirm a board price (latest observed October 5, 2026). A certificate covers a single lot, so match the batch on your vial to its certificate before relying on a result. LAP-1 (S), LAP-2 (T) and LAP-3 (R) are LA Peptides’ house labels for semaglutide, tirzepatide and retatrutide. The CJC No DAC / Ipamorelin listing reads 5 mg, but a Bioviridian certificate for it (COA5220, lot 1318) measured 5.81 mg and 5.32 mg of its two peptides, so the board compares that vial as 10 mg in total.
Bioviridian and Freedom Diagnostics provider verification; COA portal requires a free account
LA Peptides lists its certificates in a members-area COA portal, and its site says the QR code on each vial label opens that lot’s certificate. A Bioviridian Inc. certificate’s Web Verification Code (for example COA5201) opens the laboratory’s own copy at bioviridians.com, and a Freedom Diagnostics report, opened by its report code at the laboratory, names LA Peptides as the client. PeptideBenchmark’s certificate record, last reviewed October 6, 2026, holds 153 certificate-to-product relationships, including 100 backed by a Bioviridian certificate and 37 by a Freedom Diagnostics report; 134 were verified at the issuing laboratory. Of 61 products with a certificate, an endotoxin result appears for 44, a heavy-metals panel for 34 and a sterility test for 27.

Assayed content is not fill accuracy. Laboratories report net peptide content, and peptides ship as salts, so an honestly filled vial commonly assays below its gross label — a figure under 100% is not evidence of a short vial. These numbers are also not comparable between vendors: they exist only where a laboratory reports net content, so they partly reflect which laboratory a vendor uses.
