About Research Peptides Lab

US research-peptide vendor (domain Aug 2025) with a clean public storefront, transparent pricing, and fast tracked shipping, but its entire trust pitch rests on 40+ advertised third-party COAs that name no lab and cannot be opened or verified. Reputation is thin (Trustpilot 4.6/5, ~21 reviews) with no independent testing.

Pros

  • Transparent public catalog with openly listed at-market pricing, fast same-day fulfillment, tracked DHL/FedEx shipping, free over $200, and reversible card payment recourse
  • Strong research-use-only labeling, valid HTTPS, ScamAdviser Very Likely Safe, and no FDA/DOJ/seizure action on record

Cons

  • Trust pitch rests on 40+ COAs that name no testing lab, show no batch IDs or dates, and do not resolve to openable documents; zero independent corroboration (no Finnrick page)
  • Thin, young reputation (~21 Trustpilot reviews, no forum footprint) plus a contradictory refund policy (60-day money-back marketing vs Terms all-sales-final) and an anonymous operator with no entity or address

Our verdict
Avoid · 48.5/100

A plausibly legitimate, non-scam young vendor with transparent pricing and fast tracked US shipping, but no testing lab is ever named, the advertised COAs are not openably verifiable, and a ~11-month domain plus a self-contradictory refund policy (60-day guarantee vs all-sales-final) cap trust. Unverifiable until real named-lab COAs appear.
