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.

Score history and the caveats

A score only moves when the evidence does

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.
