HIGHER COMPOSITEVENDOR AUDIT
Amino Club
A large, fast-growing US shop, selling since January 2026 from a New Jersey address, with the most complete certificate set we have read: 112 lot-level certificates cover all 51 products, and every one we checked against the lab's own records matched. Identity is tested by HPLC retention time only, no buyer has published an independent test, the GLP-1s are sold under code names, refunds are refused except for transit damage, and the site names no legal entity. Prices sit well below our index on most staples. Public-data audit, no first-hand order, 67/100.
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.
