The cold chain in this trade is a gel pack and an optimistic estimate
A gel pack has a finite thermal budget, and once it is spent the payload equilibrates with whatever is outside the box. The only question is how long that takes.

The Supply Chain Dispatch
Reported from the analysis, not from a warning notice.
The health authority in India has issued a warning on falsified semaglutide injection pens found in the legitimate supply chain. The Journal has reviewed the notice and the accompanying photographs; the distinguishing features are a batch-number font difference and a needle-shield colour, neither of which a patient could reasonably be expected to detect.
Comparison of 12 certificates supplied by the reseller against the laboratory’s public archive matched 10 of them to reports commissioned by other parties, in some cases more than a year earlier. The reseller did not respond to two written requests for comment.

The document is the weakest link in this trade. A certificate is a PDF; a laboratory letterhead is an image; a lot number is a string. Nothing in the ordinary transaction allows a buyer to confirm that a given report was issued for a given vial, and the four independent services differ in whether they offer any lookup at all.
Lorcan Feeney, analytical services director at an independent laboratory, said the underfill finding was the more consequential one. "Nobody is being poisoned by a low content figure. Everybody using that vial is out by a fifth in every calculation they make."
Our series on identity confirmation covers the analytical detection of substitution in detail, including the mass differences that correspond to the commonest related compounds.

Where two methods disagree, the conservative convention is to report the lower figure. It is not universal, and whether a laboratory follows it belongs on the report.

The supplier has not disputed the finding. It has not explained the gap either.
The sequence predicts the failure mode. A methionine predicts oxidation; an asparagine followed by a glycine predicts deamidation; a cysteine predicts disulphide scrambling.
