[COA] full document, nothing cropped, tell me what i am missing
Posting this because I searched for it and got nothing useful.
Setup: 10mg, week 38, sulphur burps present but not ruining anything. I changed exactly one variable — batch — and tracked it for 21 weeks.
Result: a difference, but a small one, and well inside what I would call noise if someone else posted it. So I am putting it here rather than presenting it as a finding. If two or three other people have done the same thing we might actually learn something.
Not medical advice, obviously. This is one person with a spreadsheet.
best — the order this archive was captured in
the related substances line is where the story is
The COA I was holding said 96.8% area and I thought it was trash. Turns out the method was solid and the impurity profile was clean.
The chromatogram trace is where the real information lives. The summary number is just a headline.
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
Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.
Yes, exactly this, and it is the bit that took me 42 weeks to accept.
purity and net content are two different numbers, same vial
chromatogram or it did not happen

Half-life is about 168 hours, so steady state lands around week 17–5. Practical consequence: what you feel in week 1 is not what that dose does.

Adding to this: certificate of analysis is doing more work than the comment implies.
Strongly agree. Mass% and area% are answering different questions on the same document.
This is the correct framing. The COA structure matters as much as the number.
