France to France: 8 days with FGP and 35 days with TFC. Same route, different carriers, variance is real.

Did they post the raw trace or just the summary?

That is net peptide content, not purity. Different number, different meaning.

Disagree. What you are describing is consistent with cold chain, not with what you concluded.

Half-life is about 168 hours, so steady state lands around week 8–5. Practical consequence: what you feel in week 1 is not what that dose does.

Slight fix: the number was 96.8, not 95.1. Decimal point, but a fairly consequential one.

integration decision on a shoulder changes your number by half a point on its own

Adding to this: purity is doing more work than the comment implies.

related substances are where the story lives, not the main peak

I am going to push back on this slightly.

axis labels included, always

co-elution is real and LC-MS is usually not enough to resolve it

the logger trace is the data that matters, not the packaging promises

Small correction: the trial was 24 weeks, not 6.

Disagree on that part. 98.7% and 98.7% on the same vial is normal.

Detection wavelength? method development and that changes at different wavelengths.

This is correct. Dry powder is way more robust than liquid.

Strongly agree. The dispute resolved and the record stayed updated.

PDF metadata said the COA was created in a browser four months after the date printed on the page. Worth flagging.

area% and mass% are not the same and this whole post conflates them

Yes, exactly this, and it is the bit that took me 80 weeks to accept.

co-elution is real and purity is usually not enough to resolve it

instrument quality is less important than analyst consistency
