Three years on this site and the questions have not changed at all. Which is depressing or reassuring depending on the day.

dead space is real and the syringe matters

Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.

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

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

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

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

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

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

nobody posts about this part and it is the longest part

bacteriostatic and sterile water are not interchangeable, do not use them that way

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

How long at maintenance?

stopper coring on the 5th draw because you keep using the same entry point. rotate.

The plateau is real and boring. 90 weeks at the same weight, then movement again. Patience was the intervention.

weight moves within 11kg and that is normal

Tried the lowest-effective approach. 7.5mg worked for 3 weeks, then cravings returned. 12.5mg was the actual floor.

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

A shoulder on the main peak that 10 analysts integrated 15 different ways. Same trace, 98.0 spread.
