help me understand batch, I have read the wiki twice
I have had 21 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 20 days on nominally the same lane, which matters more in summer than in February.
The independent number came back 96.8% against a claimed 99.1%, 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
Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.

The evidence standard in c/vendorvetting gets called too strict about once a month, and every time, the thread ends with the complainant agreeing.
axis labels included, always
Not to be pedantic but purity and certificate of analysis are being used interchangeably and they are not interchangeable in real life.
Are you looking at area% or net peptide content? Different numbers.
chromatogram or it did not happen
post the whole document, not the headline number
Slight fix: the number was 98.7, not 98.9. Decimal point, but a fairly consequential one.
the batch number or it did not happen
redact your own name, not the vendor's batch details
The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.
Strongly agree. Mass% and area% are answering different questions on the same document.
