Two audits, side by side. Composite, subscores, shipping, payment, coupons. Research Peptide Hub takes the higher composite this cycle.
Brand-new (2026) research-peptide storefront with third-party COAs attributed to Freedom Diagnostics and competitive per-mg pricing. Two things hold the score back - the GLP compounds ship under proprietary house labels (now "RPH-R3", "RPH-TRZ2") rather than their real identities, which carries a regulatory-exposure deduction, and the operation has no public track record yet. Public-data audit; we have placed no test order.
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.
