Methodology
How a vendor gets on this list.
Fraud-flagged means a vendor was reported in the last 90 days for substantively misleading claims, fake COAs, or non-delivery. Manually flagged means editorial has documented a serious concern (label-quantity divergence >30%, repeated COA refusal, recall history, etc.). Low-grade means the composite (40% lab quality, 20% sentiment, 15% COA transparency, 15% reliability, 10% verified $/mg) lands at D, E, or F.
