The slide that was not in the abstract
Reported from the sessions, and from the two hours afterwards.
A shortage listing ends. 8 pharmacies now have a business model and no legal basis for it.
The document is four pages. Three of them are about dates.
Side effects, cost, supply, target: four reasons with four trajectories
The trials studied planned withdrawal. Almost nobody stops that way.
Counter-ion, water, salt: three masses with no chromatogram
Aggregates dissociate in the mobile phase and are recorded as monomer. Only a size-based separation reports them.
Why summer is a documented quality problem in this trade
The route did not close because of a rule about peptides.
Inspectors cite the relabeller trading as Vantris Bio over sterility assurance
The observation that closes a facility is rarely the dramatic one.
From the floor in Shanghai: 5 posters, one theme
Reported from the sessions, and from the two hours afterwards.
What the new the United Kingdom guidance says about stopping
The evidence base is thin and the document says so, which is to its credit.
Low endotoxin recovery: the interference nobody looks for
We submitted vials for endotoxin determination and report the results, the method and the laboratory, because a pyrogen figure without a method is as empty as a purity…
Quadrupole, time-of-flight, orbital trap: what each class can and cannot see
Calibration drift is real, unremarkable, and the reason serious laboratories run internal standards.
What the survodutide schedule assumes about a person it has never met
We work the arithmetic out in full, because it is arithmetic and it is short.

The evidence base is thin and the document says so, which is to its credit.
The slide that was not in the abstract
Reported from the sessions, and from the two hours afterwards.
Independent analysis puts a SWB tirzepatide lot at 98.3%, against 95.6% on the certificate
The report states the gradient, the wavelength and the integration threshold, which is more than most.
CPC declines, for the 24th time, to name its synthesis house
Documentation practice is the only part of vendor quality a buyer can assess before purchase.
Measuring more frequently generates more flags and not more information
What the pivotal programmes measured and how often, which is a more defensible template than most published monitoring schedules.
Why summer is a documented quality problem in this trade
The route did not close because of a rule about peptides.
From the floor in Shanghai: 6 posters, one theme
Reported from the sessions, and from the two hours afterwards.
PeptideMeter result on a Tianjin liraglutide lot lands 4.0 points below the supplier’s figure
A reminder that a purity figure is the output of a method, and that methods differ.
What a 40% rise in coupling-reagent prices does to a 20 mg vial
Follow the resin, not the catalogue.
What the trial protocols permitted, and what the labels omitted
Nausea and gastric delay attenuate over weeks at an unchanged dose. That single physiological fact is the entire justification for holding.
Janoshik, Medutest, PeptideMeter, VendorInvestigate: a capability audit
Four independent services underpin confidence in this market. All four are competent at chemistry. Microbiology is a different accreditation, a different facility and a…

A design note rather than a result: what the comparator was, and what that permits you to conclude.
PeptideMeter result on a Changsha retatrutide lot lands 3.4 points below the supplier’s figure
A reminder that a purity figure is the output of a method, and that methods differ.
Sarcopenia is a diagnosis, not a synonym for losing lean mass
The rule that a quarter of weight lost is lean tissue has been in textbooks for decades and does not survive close reading.
What the older diet-and-exercise trials found in the hip
The evidence base is one secondary analysis, several small studies and a large amount of extrapolation from bariatric surgery.
What the trials adjudicated, and how
We give background rates alongside trial rates, because an event occurring during treatment is not thereby caused by it.
Calder Vale Peptides of Skipton closes after 21 years
A proper account of an operation that existed, and of what closing it cost.
Why summer is a documented quality problem in this trade
The route did not close because of a rule about peptides.
Chengdu export categories for peptide intermediates were quietly renamed
Follow the resin, not the catalogue.
Singapore health authority warns on falsified liraglutide pens
Reported from the analysis, not from a warning notice.
The convention nobody explains before handing over the vial
A unit is a volume. A dose is a mass. The bridge between them is concentration, and concentration is a number somebody has to calculate.
An interlaboratory comparison nobody had run
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.
