Evidence summary

Modern Research Peptides COAs and evidence

The vendor's 124 official PDF reports provide unusually broad sample-specific evidence, with exact matching COAs on 78 of 81 current in-stock single-vial strengths. One historical lab link is unavailable, and three current strengths remain unmatched.

The working 25% coupon, stated shipping choices, and 4.2/5 Trustpilot profile support the 9/10 overall rating, weighted from COA 10, reputation 8, transparency 8.5, and operations 9. The review sample is small and includes service complaints; the COA score reflects the retained lab files, not customer opinions.

Modern Research Peptides COA tests and exact matches

On September 24, 2026, we enumerated 62 product groups and 133 certificate links from Modern Research Peptides' archive. Eight repeated links leave 125 unique official Freedom URLs. We retained and inspected 124 one-page lab-hosted PDFs; each prints a matching accession, search code and client MRP. The remaining historical TB-500 URL returned 404 and receives no verified label. The reports include identity and purity findings where printed, and 123 of 124 include a measured content result; the LIPO-C liquid report does not list net peptide content. One April 2 CJC-1295 No DAC 10mg report, MRP2604010067, records 5.68mg net content, or 56.8% of the labeled amount, despite 99.80% purity. A newer July report, MRP2607020449, records 10.10mg for the same listed strength. Both lot-specific results remain visible in the library. Across the distinct PDFs, 82 show endotoxin results, 36 microbial PCR results, 27 elemental-impurity ICP-MS results, and 86 fentanyl-screen results. These panels are present in selected reports, not the whole catalog. PCR screening is not a sterility test. Eighty exact current report records attach to 78 of 81 in-stock single-vial listed strengths. CJC No DAC 5mg, NAD+ 400mg, and GLP2-T 80mg have no exact match. The NAD+ 400mg archive group points to a PDF whose printed product is 500mg, so it stays unassigned to the 400mg offer.

Modern Research Peptides customer reviews

Trustpilot's exact-domain profile displayed 4.2/5 from 19 reviews on October 3, 2026. Many customers praised quick dispatch and helpful replies; a one-star review reported a missing order and unanswered messages, and a three-star review described slow communication after ordering. A newer two-star review raised a product-outcome complaint that we treat as customer opinion, not analytical evidence. The profile was unclaimed and the sample remains small. Finnrick listed Modern Research Peptides but said it had published no independent laboratory result for the vendor as of September 3, 2026. We found no substantial exact-domain Reddit review thread in the September 24 check.

Modern Research Peptides checkout and shipping

A signed-in checkout showed Visa, American Express and Discover through NMI, explicitly excluding Mastercard on that gateway. Backup credit/debit card and same-day bank payment each advertised a 2.5% payment discount; Apple Pay, Google Pay and Bitcoin were also listed, with 10% advertised for Bitcoin. Code PEPTIDEPRICES reduced a BPC-157 10 mg item from $29.32 to $21.99; standard shipping was $9.99, making the cart total $31.98. The checkout listed standard shipping at up to seven business days for $9.99, expedited at two to three business days for $14.99, and overnight at $65. The site advertises free expedited shipping at $250 and free overnight at $500. Its shipping policy makes dispatch subject to payment review and says Alaska, Hawaii and PO boxes may use USPS Priority. The refund policy permits full cancellation beforeshipment and limits returns after shipment, with exceptions for damaged or incorrect orders reported promptly.

Modern Research Peptides company disclosures

Modern Research Peptides publishes contact, shipping, refund, terms and privacy pages, a 21-plus research-use checkout attestation, and a certificate archive. The reviewed public pages did not establish a legal entity name or operating address. The archive's MRP client code is connected to this storefront by its direct links and MRP-branded vial photographs; our verification is specific to the published reports, not an assertion about every future batch.
