What has changed at Rivn Peptides, dated
Rivn Peptides since 27 August 2026: 5 dated entries, newest first, none edited after the fact.
- Trustpilot read: 4.9 across 641
97% five-star, 0% one-star.
- Score 8/10 → 10/10
claims-consistent and clean-record AWARDED (8/10 to 10/10). Disclosed timing: Rivn became an affiliate partner of ours the same day, which is what prompted the re-read, so the evidence is set out in full. In August its site showed a '4.9 / 1,247 reviews' widget against a Trustpilot record of 326 — one unverifiable claim costing two points. On 19 Sep 2026 we checked the homepage, /about, /testing and /faqs: the widget is gone, replaced by a section pointing at the real Trustpilot profile; no in-house review count appears anywhere; the FAQ's 99%+ purity claim matches the published certificates (99.81%, 99.91%); and a searchable 47-certificate library with per-lot purity, net content, heavy metals and endotoxin has replaced the 7 loose images we saw on 6 Sep. No regulator action found. The vendor fixed the defect; the rubric does not withhold points as a penalty for having once had one. Still vendor-stated and unverified: ISO 9001 facilities, 'Certified GMP', and the lab's ISO/IEC 17025 accreditation
- Score 10/10 → 9/10
CORRECTION, same day: claims-consistent WITHDRAWN (10/10 to 9/10). The award above was inconsistent with how we scored the same defect elsewhere. Rivn's site states 'Manufactured in ISO 9001 certified facilities', 'Certified GMP', and ISO/IEC 17025 for its laboratory, publishing no certifying body, certificate number or register entry for any of the three. We withheld this exact point from Ameano Peptides for marketing an 'accredited third-party' while naming no lab, and from Idun Peptides for 'accredited laboratories' plural against a single lab on every certificate — both vaguer claims than these. Our own evidence file had already recorded the three claims as unverified; we noted them and awarded the point anyway, which was an error. Disclosure: Rivn became our affiliate partner the same morning, and the re-read that caught this happened while the site owner was pressing to have our primary partner shown first, so the correction benefits a commercial interest of ours. It stands on the four prior rulings, not on that. The other 9 points are unchanged and the certificate library and removed review widget are real improvements. Next: the same criterion is being re-checked across all 59 vendors, our partners included — if it was applied loosely once it was probably applied loosely elsewhere
- Score 3/8 → 8/10
re-issued under rubric v2 (was 3/8); not awarded: claims-consistent, clean-record
- First scored: 3/8
first assessment under rubric v1 (corrected 19 Sep 2026: this row read 15/8, an impossible score, from a transcription error when the ledger was backfilled; the v2 row below records the original as 3/8)
