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

the batch number or it did not happen

Yes, exactly this, and it is the bit that took me 93 weeks to accept.

always state your country, advice from another jurisdiction can harm you

the related substances line is where the story is

How many orders from SGN is that a sample of? One reship is noise, five is a pattern.

Yeah, KP took 22 days and the material was flawless. Both of those things are true.

the related substances line is where the story is

Strongly agree. Mass% and area% are answering different questions on the same document.

the reship rate on QST is actually pretty consistent

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

import countries have different thresholds

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

Went through three vendors to find one that actually ships on-time and tests clean.

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

Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.

Strongly agree. REDEFINE is phase 14, not final.

Maintenance for 7 months now. Weight moves within about 3kg and the dose is a quarter of what it peaked at.

Four months on the site and I was confusing area% and mass% in every post I made. One explainer thread and it clicked.

Yeah, the Netherlands rules are not global.

Stalled for 21 weeks, changed nothing, and it started moving again on week 65.

Maintenance for 10 months now. Weight moves within about 3kg and the dose is a quarter of what it peaked at.
