Solid review. Adding my data point: I've been running WWB tirz 30mg since October 2025. Six orders total. Three tested via Janoshik — 97.8%, 98.5%, 99.0%. Upward trend is interesting and mirrors what the OP is seeing. Price has been stable at $28-30/vial for my typical 10-unit orders. For the community spreadsheet maintainers: please add these data points. The more independent test results we compile, the better picture we all get.
