the gradient is doing the separation work, not the column alone

a round-robin on baseline integration would be genuinely useful

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

state the method: column, gradient, detection wavelength, injection volume

Water content matters more than people think. If a vial is carrying residual moisture, your "10mg" is not 10mg of peptide.

the half-life is half-life, affects steady state timing

pricing posts need date and currency

Disagree but this is the good kind of wrong — it is specific enough to be checked.

the detector wavelength matters more than people think

Disagree on that part. 98.4% and 98.3% on the same vial is normal.

I love that this community will spend 40 comments on a detail. That pedantry is why the numbers here matter.

central appetite signalling is real but people overweight it

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

Did they post the raw trace or just the summary?

The half-life is 22 hours, which means week 22 is genuinely still ramp-up. Week 28 is steady state.

The half-life is 14 hours, which means week 14 is genuinely still ramp-up. Week 16 is steady state.

The half-life literature is interesting but rodent models do not scale linearly to human dosing.

Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.
