EZ Peptides scores 94/100 in pepmg's criteria-based Vendor Score, which rates only what a vendor publishes about lab testing and about itself, not its products and not its prices. What we observed: most COAs openable at the testing lab (158 of 230). The biggest credibility signal pepmg weighs is how a vendor publishes lab tests: the documents counted above open at the testing lab's own site (Janoshik), where the lab itself can confirm the result, and the rest are hosted by the vendor, where it cannot. Neither price nor catalog size affects this score, but for context it prices around the tracked median across the compounds it shares with other tracked vendors, over 35 tracked listings. Its prices are machine-readable and it publishes an About page, and the domain has been online about 2.8 years. This rates what EZ Peptides publishes about lab testing and about itself, not the purity or authenticity of any vial, which pepmg can't verify, so read the COAs yourself. Research use only.

• Strength Third-party COAs, results hosted at the lab (Janoshik) — strongest public signal — 230 COA documents found, 158 of them openable at the testing lab's own site
