VENDOR AUDIT
Particle Peptides
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.
