Germany: water content, and what it actually costs here
Confession thread, sort of.
I went from 15mg to 7.5mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 22 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 early fullness I did not need and a data point I cannot interpret. Two lessons in one.
Posting it in the hope that somebody at week 66 reads it before doing the same thing.
best — the order this archive was captured in
post the whole document, not the headline number
Retitled to remove editorialising. Put the evidence in the body.
Metadata check caught a COA that was created in a browser four months after the analysis date. Not evidence of fraud, but worth flagging to Homopeptide.
Sent one vial to Janoshik and VendorInvestigate. 98.3% and 98.4%. Cost me more than the vial did and I would do it again.
Are you looking at area% or net peptide content? Different numbers.
the related substances line is where the story is
Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.
Respectfully this is a sample of one presented as a finding.

Cosigning. The batch number is load-bearing information.
axis labels included, always
the method line is doing real work, not just window dressing
chromatogram or it did not happen
Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.
area% is not mass%, and here is exactly why it matters
redact your own name, not the vendor's batch details
This is the correct framing. The COA structure matters as much as the number.
Three years on this site and the questions have not changed at all. Which is depressing or reassuring depending on the day.
I am going to push back on this slightly.

Adding to this: COA is doing more work than the comment implies.
Strongly agree. Mass% and area% are answering different questions on the same document.
