What a split-sample exercise can establish, and what it cannot
Duplicate submissions under different names test within-laboratory repeatability, which is a different quantity from between-laboratory reproducibility.
The badge economy, and what it is actually certifying
Every step between the laboratory report and the product page removes information, and the badge is the last step.
HJ names the synthesis and fill sites behind its catalogue
Documentation practice is the only part of vendor quality a buyer can assess before purchase.

What Medutest can tell you about a vial by weighing its water
Water is a reactant in hydrolysis, a plasticiser that mobilises the amorphous matrix, and a carrier for everything else. All three matter.
What changed at SGN in October, and what the company says prompted it
Documentation practice is the only part of vendor quality a buyer can assess before purchase.
Sending the same vial twice, under two names
Two years ago we ran an anonymised version of this comparison and promised a named one. This is it, with every method printed in full.
CPC names the synthesis and fill sites behind its catalogue
Documentation practice is the only part of vendor quality a buyer can assess before purchase.
What the four services actually offer, test by test
Endotoxin is the more tractable of the two questions, and a kinetic chromogenic determination is neither slow nor exotic. It is simply not on the menu.
Set the threshold at a tenth of a per cent and the small impurities vanish
Baseline placement under a tailing peak is a judgement call with a direct effect on the area. It is one of the few places where two competent analysts genuinely disagree.
Independent analysis puts a TFC tirzepatide lot at 97.7%, against 95.0% on the certificate
The report states the gradient, the wavelength and the integration threshold, which is more than most.
SSA names the synthesis and fill sites behind its catalogue
Documentation practice is the only part of vendor quality a buyer can assess before purchase.
Holograms, QR codes and other things that are not verification
Reported from the analysis, not from a warning notice.
The named comparison we promised two years ago
The Journal submitted split samples from single lots to three assay services, under names unconnected to this publication, and published each method alongside each result.
What Sweden customs does to a parcel it has decided to examine
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.
Independent analysis puts a WXT tirzepatide lot at 96.4%, against 93.6% on the certificate
The report states the gradient, the wavelength and the integration threshold, which is more than most.
Custody, condition and the temperature nobody logged
A result on one vial generalises to a batch only if the vial was drawn in a way that makes it representative — and nobody records how it was drawn.
VendorInvestigate result on a Wuxi semaglutide lot lands 2.1 points above the supplier’s stated figure
The supplier confirmed the determination and supplied the method behind its own figure inside a week.
