VENDOR AUDIT
Summit Biotech
Held for reference, not a current recommendation. The link we drew from the December 2024 FDA warning letter to "Summit Research Peptides" to the current Summit Biotech site is an inference, not a record - the letter names summitpeptides.shop, while summitbiotechusa.com was registered months later; the only hard tie is a same-name domain that 301-redirects to it. The catalog is login-walled, our data is from May 2026, and there is no independent buyer record, so readers cannot re-check anything. We have removed it from the ranked vendor list.
