Limitless Biotech
Lot-numbered certificates on its product pages, none in our lab mirrors; Finnrick passes 7 of 22 samples; an Ohio pharmacy-board case names it as a clinic's unlicensed DSIP source. Public-data audit, no first-hand order, 47/100.

Two audits, side by side. Composite, subscores, shipping, payment, coupons. Summit Biotech takes the higher composite this cycle.

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.
