VENDOR MATCHUP · AUDITED

Limitless Biotech vs Research Peptide Hub

Two audits, side by side. Composite, subscores, shipping, payment, coupons. Research Peptide Hub takes the higher composite this cycle.

Composite score

47
OF 100
VENDOR AUDIT

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.

vs
HIGHER COMPOSITE
66
OF 100
VENDOR AUDIT

Research Peptide Hub

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.
