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

Composite score

62
OF 100
VENDOR AUDIT

Particle Peptides

Slovak shop that publishes its full certificate archive: 79 reports from Apigenex and Liquilabs, 9 checkable on the lab's own server. Older lots run short of label; 2025-26 Liquilabs lots meet it. Sells retatrutide as "GLP-3". Public-data audit, no first-hand order, 62/100.

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.
