Disclosure: Purgo Labs is our affiliate partner; we earn nothing from Modern Research Peptides. Scores come from the public rubric, which has no partnership input.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.

Certificates are hosted by the lab, not the vendor: the BPC-157 10mg report for lot MR0571WED is served from coas.freedomdiagnosticstesting.com (Search Code MRP2606250345, received 25 Jun, reported 28 Jun 2026), and the lab's own lookup returned 'Document found' on 29 Sep 2026.
Two vials measured on the report — 11.21 and 11.43mg on a 10mg label (average 11.32mg), purity 99.76 / 99.78% by HPLC-UV, LC-MS identity confirmed, endotoxin and fentanyl screens included. Product titles print the measured content next to the label ('TB-500 10mg (11.58 mg)', 'TB-500 5MG (5.69 mg)').

Only vials both vendors list at the same size, read on each vendor's product page on the date shown. "After code" is list × the code's stated discount — a calculation, labelled as one; stacking with sale pricing is not cart-tested.

What we found at Modern Research Peptides
Read 29 September 2026 on the vendor's own pages
The paperwork is unusually good for a vendor this new: the lab, not the vendor, hosts every certificate, each one carries two measured vials, and the product titles put the measured milligrams beside the label. What is missing is a company — a Gmail address and dead policy links are all there is behind the storefront, and nineteen Trustpilot reviews do not yet say much. 8/10 on the vial; ask who you are paying.

Where Modern Research Peptides ranks by compound
Modern Research Peptides appears in 2 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-09-298/10 — first assessment (rubric v2); not awarded: review-base (4.2 / 19), identity (no entity or address; Gmail contact) — certificates served from the lab's own domain
Purgo Labs: the caveat
Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
Modern Research Peptides: the caveat
No legal entity or street address anywhere — the contact page is a Gmail address and the footer's Refund Policy and Terms of Service links 404 (the Terms and Conditions page that does exist says all sales are final). Trustpilot 4.2 across 19 reviews, unclaimed — not yet a review base. A discount-code post in a ranking site's subreddit is the bulk of its Reddit footprint.
