Trust signals
Rivn publishes a public testing gallery with 37 report images during the August 14, 2026 review. The reports name Freedom Diagnostics in Nashville and link results to a lot or batch. PeptidePrices inspected three reports: BPC-157/TB-500 accession 2604030206 (search code RIVN2604030206, lot 7831), Cagrilintide accession 2604030200 (RIVN2604030200, lot 2217), and KPV accession 2606290305 (RIVN2606290305, lot KPV-122). Each exact accession appeared in Freedom Diagnostics' official public file list. The sampled scope included LC-MS identity, HPLC purity, and net content. It did not include sterility, endotoxin, or heavy-metals results, and this review did not inspect every gallery image. Match the product and lot to the report before relying on it. Affiliate status does not affect the rating.
Evidence summary
Rivn provides unusually strong public evidence for a new vendor. PeptidePrices matched three sampled Freedom Diagnostics accessions to the laboratory's official public file list, and each report linked the tested results to a product lot.
The 9/10 rating combines a 9 for COA practices, 10 for reputation, 7 for transparency, and 9 for operations. The remaining limits are the short company history, an unnamed owner, limited evidence outside Trustpilot, and no sterility, endotoxin, or heavy-metals results in the sampled reports.
