Peptriva's Dual-Verification Protocol: Each Batch Undergoes Independent Third-Party U.S. Lab Re-Testing
Peptriva announces its Dual-Verification Standard, where every peptide lot is tested at manufacture and re-tested by an independent U.S. lab before shipping, with results published in a searchable COA library.
Peptriva, a California-based supplier of research peptides, today announced that every product lot now undergoes a rigorous Dual-Verification Standard. Under this protocol, each lot is analytically tested twice before shipment: once at the manufacturer and again by an independent U.S. laboratory upon arrival at Peptriva's cold-chain facility. The results of both tests are published in a public, batch-searchable Certificate of Analysis (COA) library, ensuring researchers can verify the exact documentation for the vial in hand.
The process begins with the manufacturer's COA, which details purity by high-performance liquid chromatography (HPLC), identity by mass spectrometry, heavy-metal screening by ICP-MS, endotoxin testing, and PCR microbial screening. Once the lot arrives at Peptriva's facility in Paramount, California, it is re-assayed by Freedom Diagnostics, an independent U.S. testing laboratory, before being cleared for sale. Both sets of results are batch-matched to the lot number printed on each vial and are accessible through Peptriva's public COA library.
"In this industry, purity claims are everywhere and verification is rare," said a Peptriva spokesperson. "We built Peptriva on a simple rule: identity and purity are established analytically, not asserted. Two independent tests per lot, published where anyone can check them - hold us to the third-party numbers."
The Dual-Verification Standard applies across Peptriva's catalog of 40 compounds, including GLP-1 analog reference compounds such as retatrutide, semaglutide, and tirzepatide, as well as cytoprotective sequences, growth-hormone secretagogues, copper peptides, and laboratory consumables. All products are specified at 99% purity or higher. Orders placed before 5 p.m. ET ship the same day from Peptriva's California warehouse, with free tracked two-day delivery on every U.S. order and a 30-day money-back guarantee. No account is required to view pricing or Certificates of Analysis.
All Peptriva products are supplied strictly for in vitro laboratory research use only and are not for human or veterinary use. The company's storefront is age-gated to researchers 21 and older.
