Feel Good Peptides

Feel Good Peptides scores 90/100 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 (90 of 131). 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 (Horizon Analytical), 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 about 1.2x the tracked median across the compounds it shares with other tracked vendors, over 37 tracked listings. Its prices are machine-readable and it publishes a brief About page, and the domain is newer, online since Dec 2025, which pepmg counts as neutral rather than a mark against it. This rates what Feel Good 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 lab named (Horizon Analytical) — vendor-hosted documents with lab verification links — 131 COA documents found, 90 with links to the testing lab's own site (some labs restrict automated access)
