Adding the measurement that post #2 says would settle it.
Reconstitution behaviour is a legitimate home observation. A cake that will not dissolve, a solution that hazes, visible particulate — all are real information and all are free.
Two sources, same conclusion, and I could not rule out that one copied the other.
Precision of home tests: most consumer-accessible devices are not precise to the level people want ("is this 99% pure or 97% pure"). They give a yes/no or a rough category, not a quantitative number.
A partial answer, offered because a partial answer beats none.
Post #42 is right about the mechanism and I think understates the practical bit.
Where a home observation and an independent result disagree, the independent one is measuring something more specific. That does not make the home observation useless — it makes it a different measurement.
The variance between people here is larger than the effect being discussed.
The honest cost comparison is a home kit against a single independent submission. For most people the second answers the question and the first answers a different, smaller one.
Marking that as an opinion rather than a finding.
Agreed on all of that, and I have nothing to add to it.
Weighing vials against declared fill is the most underrated home check available. It needs a balance with adequate resolution and it catches fill problems that no certificate would show.
Immunoassay limitations: tests that use antibodies have cross-reactivity limitations. An antibody raised to semaglutide will cross-react to some degree with tirzepatide and other structurally similar compounds. The test result conflates them.

Cost versus information: making the trade-off explicitly
Cost versus information: making the trade-off explicitly Writing it up because I had to work it out twice and would rather nobody else did. Asking about cost versus information directly, because I have read…
