Onyx Bio Labs

Onyx Bio Labs scores 79/100 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: a few COAs openable at the testing lab (23 of 159). 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 (Chromate Labs, Freedom Diagnostics, Janoshik, Kovera Labs), 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 20 tracked listings. Its prices are machine-readable and it publishes a brief About page, and the domain has been online about 1.2 years. This rates what Onyx Bio Labs 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 lab named (Kovera Labs, Chromate Labs, Freedom Diagnostics, Janoshik) — vendor-hosted documents with lab verification links — 159 COA documents found, 23 with links to the testing lab's own site (some labs restrict automated access)
