customs clearance often breaks the cold chain, factor that in

Yeah, data logger is the only acceptable proof.

Are you looking at area% or net peptide content? Different numbers.

Peak temperature and how long at that temperature?

purity and net content are two different numbers, same vial Disagree on that part.

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

Yeah, data logger is the only acceptable proof.

chromatogram or it did not happen

lyophilised powder is far more forgiving than reconstituted solution

excursion claims need a logger trace or a photo at unboxing, not "it felt warm"
