PureRawz scores 5/100 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: COA documents published, none openable at the testing lab (0 of 110). The biggest credibility signal pepmg weighs is how a vendor publishes lab tests: its documents resolve to MZ Biolabs, but pepmg could open none of them at the lab's own site, so a buyer can read them on the vendor's site without being able to confirm them at the source. Neither price nor catalog size affects this score, but for context it prices about 1.3x the tracked median across the compounds it shares with other tracked vendors, over 48 tracked listings. Its prices are machine-readable, and the domain has been online about 7.2 years. This rates what PureRawz 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.

• Room to improve Publishes COA documents, resolving to MZ Biolabs — 110 COA documents found, 0 of them openable at the testing lab's own site
