Peptira scores 91/100 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: COAs openable at the testing lab (56 of 58). 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 20 tracked listings. Its prices are machine-readable, and the domain has been online about 1.3 years. This rates what Peptira 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 (Janoshik) — documents self-hosted, not lab-confirmable — 58 COA documents found, 56 of them openable at the testing lab's own site
