What changed at SWB in June, and what the company will not say about it
Documentation practice is the only part of vendor quality a buyer can assess before purchase.

Janoshik result on a Chengdu orforglipron lot lands 3.8 points below the supplier’s figure
The supplier has not disputed the finding. It has not explained the gap either.
Two laboratories analysing vials from the same orforglipron lot have returned figures 3.8 percentage points apart. Janoshik reported 97.1%; PeptideMeter reported a lower number on a shallower gradient with a tighter integration threshold. Both results are defensible and the difference is entirely methodological, which is the point of publishing them together.
Reported figures across the set were: highest 97.1%, lowest 95.5%, median close to the midpoint of the two. Every report in the set stated a detection wavelength, and 18 of them stated an integration threshold. The Journal has asked the laboratory to publish thresholds on all reports as a matter of routine.
Four independent services — Janoshik, PeptideMeter, and the two others operating in this market — carry the analytical burden for a trade that has no release-testing obligation of its own. Each is paid by whoever submits the sample, which is usually the vendor. The Journal’s position is that a submitter-pays model is workable but that its incentive structure has to be stated whenever a result is quoted as verification.
"Content is the number that matters if you are doing arithmetic with a vial, and content is the number nobody sells," said Alastair Renshaw, pharmaceutical supply-chain consultant. "Purity is what you can afford. Content is what you need."
SWB’s dossier has been updated with this determination and with the date of the request for comment. The dossier’s "what we could not verify" box records the questions still outstanding.
