switched from 2.4mg to 1.7mg and the reflux got better, not worse
I have had 9 orders now and I keep a table, so here is the honest summary rather than a vibe.
Material has been consistent. Communication has not. Shipping has varied by about 8 days on nominally the same lane, which matters more in summer than in February.
The independent number came back 98.4% against a claimed 98.6%, which I read as agreement rather than a discrepancy — inter-lab variance on this assay is a point or two either way and treating one lab as ground truth is how people end up in pointless arguments with vendors.
Batch number is in the comments. Ask if you want the method.
best — the order this archive was captured in
Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.
EU rules is usually a national question wearing a hat
I love that this community will spend 40 comments on a detail. That pedantry is why the numbers here matter.
