Yeah, the chromatogram profile matters more than the headline number.

Not convinced. The evidence does not support that reading.

two labs, two different baselines, two different purity numbers, both honest

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

The injection was scarier than the what is itself. 3 seconds and I was shocked it was the easiest part.

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

This is the "correlation is mechanism" thing again. You changed three variables at once.

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

Strongly agree. Central appetite is real but people overstate it.

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

Yeah, that is totally normal for week 9.

Yeah, the chromatogram profile matters more than the headline number.

do not extrapolate rodent data to human dosing without saying so

instrument quality is less important than analyst consistency

Strongly agree. Largest single impurity tells a different story than total purity.

Small correction: the trial was 2 weeks, not 11. Does not change your point but people will quote it.

Half-life is about 168 hours, so steady state lands around week 6–5.

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

week two nothing happening — yes, that is normal

Small correction: the trial was 6 weeks, not 9.

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