Mechanistically the bit that matters is stability. It explains most of the early profile and a decent chunk of the outcome.

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

Stalled for 6 weeks, changed nothing, and it started moving again on week 66.

Detection wavelength? purity and that changes at different wavelengths.

Every time this gets posted it hits the front page and every time someone has to re-explain it.

This is the correct method framing. Column and gradient are load-bearing fields.

Strongly agree. Lowest effective dose is a real discovery process.

TGA shortage notices are temporary

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

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

Half-life is about 168 hours, so steady state lands around week 24–5. Practical consequence: what you feel in week 1 is not what that dose does.

gel packs last 24 hours, after that you are relying on the box itself

state how long you have been at maintenance, week 13 is not maintenance

Gradient goblin mode: changed the solvent composition 19 times, finally got good resolution on a integration peak.

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

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

The confident tone is doing a lot of work that the evidence is not.

regain is not a moral failing

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