Two audits, side by side. Composite, subscores, shipping, payment, coupons. Particle Peptides takes the higher composite this cycle.
EU-based vendor with the deepest catalog-COA surface in our cohort and a clear methodology improvement curve from 2024 to 2025+. 2024-vintage Apigenex-tested batches show a content-vs-label gap (70–80% measured content on label-stated quantities); 2025+ Liquilabs assays meet label. Carries Retatrutide under the alias "GLP-3" — buyers searching for retatrutide may not realise.
Brand-new (2026) research-peptide storefront operating under the VeloPep Labs name, with third-party COAs via Freedom Diagnostics and competitive per-mg pricing. Two things hold the score back from its catalog promise — the GLP compounds ship under proprietary house labels ("GLP-3 RT", "GLP-2 TRZ") rather than their real identities, and the operation has no public track record yet. Public-data preview; first-hand audit pending.
