Rivn Peptides gets our 9/10 rating (Highly Trusted), with 47 lab reports (COAs) on file. See how scores are calculated →
The four factors average 8.8 by weight, which rounds to 9/10.
Direct answer
PeptidePrices rates Rivn Peptides 9/10. Its retained archive contains 47 unique Freedom Diagnostics reports, all matched to specific official laboratory records by printed fields and analytical graphs. Fifteen September reports add endotoxin, PCR microbial and metals results; 32 earlier reports measure identity, purity and content. Reports with conflicting units, missing nominal units or unspecified blend ratios remain visible without an exact product match. The customer-review and company evidence is separate from these laboratory findings.
Testing lab: Freedom Diagnostics
Evidence summary
Rivn provides strong public laboratory evidence for a new vendor. PeptidePrices retained 47 unique Freedom Diagnostics reports from 53 complete exports and matched each to a specific official laboratory file by its printed fields and analytical graphs.
The 9/10 rating combines a 9 for COA practices, 10 for reputation, 7 for transparency and 9 for operations. The laboratory archive includes 15 September reports with LAL endotoxin, PCR microbial and ICP-MS metals panels, alongside 32 earlier identity/purity/content reports. The remaining company limits are its short history, an unnamed owner and limited independent discussion outside Trustpilot.
Rivn Peptides is the storefront of Rivn Research LLC. It publishes a street address in Gallatin, Tennessee, a phone number, a support email, and weekday business hours. Its terms use Tennessee law. The Rivn Peptides domain was registered in January 2026. The current Rivn Research storefront domain was registered in August 2026.
Reviewed October 4, 2026: Rivn’s public archive links 53 complete one-page PDF exports representing 47 unique Freedom Diagnostics reports. All 47 match specific official laboratory records by printed client, accession, product, lot, date, results and analytical graphs; duplicate exports do not inflate the certificate count. Fifteen September reports include LC-MS identity, HPLC-UV purity, measured content, LAL endotoxin passes at an assay sensitivity of ≤0.05 EU/mL, PCR results of no detectable microbial DNA, and ICP-MS passes for arsenic, cadmium, lead and mercury. The other 32 reports show identity, purity and content without those additional panels. PCR microbial screening is not a sterility culture. Examples include Tirzepatide 60 mg, lot TR60-7311, at 99.81% purity and 68.91 mg; Retatrutide 10 mg, lot RT10-4553, at 99.99% and 13.80 mg; and NAD+ 500 mg, lot Nad500-78, at 99.96% and 612.21 mg. The Epithalon report prints 10 g while its storefront card says 10 mg, so it does not supply a 10 mg product match. Reports with missing nominal units or unspecified blend component ratios remain inspectable without exact listing eligibility. The archive covers January–September 2026 samples; currently shipping physical lots were not independently established.
After Rivn moved its storefront, Trustpilot merged the old and new profiles. The live profile listed 4.9/5 from 607 reviews. Recent reviews commonly described fast shipping, packaging, and customer support. Trustpilot states that Rivn asks customers to review; independent discussion outside Trustpilot was limited during this review.
