the Netherlands: area percent, and what it actually costs here
Confession thread, sort of.
I went from 5mg to 1.7mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 8 weeks later, at which point I had no way of knowing whether the dose increase did anything or whether it would have broken anyway.
So now I have injection-site soreness I did not need and a data point I cannot interpret. Two lessons in one.
Posting it in the hope that somebody at week 69 reads it before doing the same thing.

The chromatogram trace is where the real information lives. The summary number is just a headline.

This is the correct framing. The COA structure matters as much as the number.
the method line is doing real work, not just window dressing
no "is this good?" without saying what the compound and claimed purity are
area% is not mass%, and here is exactly why it matters
the batch number or it did not happen
redact your own name, not the vendor's batch details
I love that this community will spend 40 comments on a detail. That pedantry is why the numbers here matter.
Strongly agree. Mass% and area% are answering different questions on the same document.

Tested the GLB raw material and a reseller vial side-by-side. Same purity claim, different impurity profiles. Handling matters.

purity and net content are two different numbers, same vial

Disagree on that part. 98.4% and 98.3% on the same vial is normal.
Are you looking at area% or net peptide content? Different numbers.
What were the related substances listed individually?

What were the related substances listed individually?
Yes, exactly this, and it is the bit that took me 53 weeks to accept.
Cosigning. The batch number is load-bearing information.
axis labels included, always
chromatogram or it did not happen
Not to be pedantic but certificate of analysis and batch are being used interchangeably and they are not interchangeable in real life.

Removed a chain here. The rule is one line long and it is not negotiable.
