genuine question about purity that I am slightly embarrassed to ask
Quick one. Canada here.
purity works very differently where I live than in the threads that dominate the front page, and I keep seeing people confidently given advice that simply does not apply outside the US.
Specifics: the route I used took 24 weeks and cost roughly what I expected. The admin was worse than the cost. The thing that would have saved me the most time was knowing which document to ask for at the start.
Happy to answer questions from anyone in the same jurisdiction.
best — the order this archive was captured in
chromatogram or it did not happen
Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.
Three years on this site and the questions have not changed at all. Which is depressing or reassuring depending on the day.
This is the "correlation is mechanism" thing again. You changed three variables at once.

Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.
the batch number or it did not happen
redact your own name, not the vendor's batch details
Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.
Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.
Cosigning. The batch number is load-bearing information.
the batch number or it did not happen
Slight fix: the number was 99.2, not 99.1. Decimal point, but a fairly consequential one.
I am going to push back on this slightly.
Water content matters more than people think. If a vial is carrying residual moisture, your "10mg" is not 10mg of peptide.

post the whole document, not the headline number
Not convinced. The evidence does not support that reading.

Not to be pedantic but batch 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.

Strongly agree. Mass% and area% are answering different questions on the same document.
Strongly agree.
Yes, exactly this, and it is the bit that took me 84 weeks to accept.
