Peptide Partners

Peptide Partners scores 82/100 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 (149 of 287). 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, Kovera Labs, TrustPointe Analytics), 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 below the tracked median across the compounds it shares with other tracked vendors, over 43 tracked listings. Its prices are machine-readable, and the domain has been online about 1.6 years. This rates what Peptide Partners 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 (Chromate Labs, TrustPointe Analytics, BioRegen, Kovera Labs) — vendor-hosted documents with lab verification links — 287 COA documents found, 149 with links to the testing lab's own site (some labs restrict automated access)
