Research Peptides Lab Products, Prices & COAs

Research Peptides Lab is a United States research-material storefront. Its exact domain was registered on August 17, 2025. The site publishes support@researchpeptideslab.com, U.S.-only shipping terms, and a public report library. PeptidePrices did not find a legal entity, named owner, or street address on the reviewed public pages.

The public COA page linked 49 images representing 38 distinct Freedom Diagnostics accessions. PeptidePrices checked every exact search code against Freedom Diagnostics' published index, downloaded all 38 issuer-hosted PDFs, and compared every vendor image with its corresponding original. All 49 images matched. PeptidePrices found no evidence that Research Peptides Lab edited the certificates. Twenty-seven issuer originals themselves show receipt on December 31, 2025 and reporting on January 1, 2025, so that impossible chronology is an issuer-record error. All 38 reports state identity and HPLC purity; ten include measured content and 28 say content was not requested. None show endotoxin, sterility, heavy-metals, or microbial panels.

Trustpilot displayed 4.6/5 from 25 exact-domain reviews on August 24, 2026. The record is positive but small and concentrated at five stars. The vendor's product page separately showed 373 reviews at the top, 195 in its tab and summary, and only seven generic review cards embedded directly in the page source. Because no independent ledger was exposed and the totals conflict, PeptidePrices excludes that vendor-published display from reputation scoring. Customer opinion does not establish identity, purity, content, or sterility.
