Independent desk-research record
The strongest batch-specific COA evidence in this set — a named independent lab verified one product's Certificate of Analysis — alongside a named legal entity and a detailed EU delivery table.
Calculated from 8 weighted, source-linked categories.
This record has completed the minimum evidence standard: category rationale, source-linked citations and a calculated score are published below.
PARTICLE s.r.o. publishes a real, current, batch-specific Certificate of Analysis (Thymosin Beta-4/TB-500, batch LYO-0736, tested 3 Sept 2026) issued by named independent lab Liquilabs s.r.o. (Zlatníky-Hodkovice, Czechia), covering peptide screening, FTIR, mass spectrometry, microbial and endotoxin testing at 99.8% purity. Only one product's COA was opened during this review, so catalogue-wide consistency is not confirmed. The company publishes a named entity, address, phone, email and hours, but GMP/ISO/regulatory claims are self-stated and no business registration number is shown.
