[Resolved] the QST batch dispute — vendor retested at their own cost, numbers matched, my error
Full timeline, because the accusation was mine and it was loud. June: my sema 10mg tested well under the COA. I posted it as a below-spec result and named the vendor. Three days later: QST offered to retest the retained sample from batch QST-2506 at their own cost, and to send me both reports regardless of outcome.…
"Reconstituted, coat pocket, conference, home again" is the entire explanation and it is a genuinely useful one, because it is the same finding as the 61% thread.
Dry powder tolerates abuse. Reconstituted solution does not. Two days in a coat pocket at body temperature is a far more aggressive exposure than a week in a courier van, and nobody thinks of it that way because it happened at home.
i have written thousands of words about cold chain and i put a mixed vial in a coat. i am not going to pretend that is anything other than embarrassing.
It is also the second accidental data point on real-world reconstituted degradation this quarter, and there is almost none of it published. Crossposting with permission.
i will lend anyone a logger who wants to run their own coat-pocket experiment deliberately. genuinely.
this is the most niche offer on the internet and i want to take you up on it
modmail me. four loggers, all idle, all bored.
