Independent analysis puts a SWB dulaglutide lot at 98.6%, against 96.9% on the certificate
The result is unremarkable. What the report omits is not.

Diminishing returns, quantified
Where the curve flattens, what flattens with it, and what does not.
The interventions with trial support, and the much longer list without
Dietary measures are widely recommended, plausible on mechanism, and supported mainly by observational data and clinical experience.
Aggregation: the impurity your chromatogram dissolved before it looked
We describe each pathway in enough chemical detail to explain why it is invisible to the method the trade uses, because that is the part which has practical consequences.
Holograms, QR codes and other things that are not verification
Reported from the analysis, not from a warning notice.
The quiet end of the relabeller trading as Vantris Bio
A proper account of an operation that existed, and of what closing it cost.
A supplier suspends shipping to Argentina after 11 consecutive customs detentions
The route did not close because of a rule about peptides.
Holograms, QR codes and other things that are not verification
Reported from the analysis, not from a warning notice.
Priming a pen is not optional
Aseptic technique here is four steps and none of them are difficult. They are, however, routinely compressed to two.
The word “confirmed” is doing an enormous amount of work on this certificate
An intact mass measurement establishes elemental composition, at best. The number of distinct sequences consistent with a given composition is astronomically large.
Independent analysis puts a WWB semaglutide lot at 95.3%, against 94.2% on the certificate
The report states the gradient, the wavelength and the integration threshold, which is more than most.
Inspectors cite the relabeller trading as Vantris Bio over sterility assurance
The observation that closes a facility is rarely the dramatic one.
Why summer is a documented quality problem in this trade
The route did not close because of a rule about peptides.
SURPASS-2 extension data: what happens after the trial stops
A design note rather than a result: what the comparator was, and what that permits you to conclude.
The supply gap as a clinical event
A supply interruption is a discontinuation with no notice, no taper and no plan. That is a distinct clinical situation.
Inspectors cite Halvard & Pike Apothecary of Portland, Maine over sterility assurance
The observation that closes a facility is rarely the dramatic one.
The slide that was not in the abstract
Reported from the sessions, and from the two hours afterwards.
A supplier suspends shipping to Portugal after 3 consecutive customs detentions
The route did not close because of a rule about peptides.
SURPASS-2 misses on a secondary endpoint the coverage has not mentioned
A design note rather than a result: what the comparator was, and what that permits you to conclude.
The out-of-range flag is a statistical convention with a printer attached
Two sources of noise sit under every number: how reproducible the assay is, and how much the analyte varies within the same person on the same day.
Why the independent testing market grew a chemistry arm and not a microbiology one
The absence of microbiological capability in this market is a commercial fact with a straightforward explanation, and it is worth understanding before blaming anybody for it.
What STEP 4 and SURMOUNT-4 actually established
What the trials measured was continuation against withdrawal. What patients want to know is continuation at a lower dose, and that study has largely not been done.
Canada declines to reimburse tirzepatide outside a specialist service
Efficacy was never the question in this appraisal. Duration of treatment was.
STEP 4 misses on a secondary endpoint the coverage has not mentioned
A design note rather than a result: what the comparator was, and what that permits you to conclude.
What the new India guidance says about stopping
The evidence base is thin and the document says so, which is to its credit.
LAL, kinetic chromogenic, recombinant factor C: three ways to the same figure
Three compendial method families are in routine use and a fourth, based on a recombinant enzyme rather than crab lysate, is now compendial in its own right.
Every fortnight, every third week, seasonally: an unstudied practice
What the exposure arithmetic says about a fortnightly schedule, and where the arithmetic stops being informative.
Norway caps tirzepatide prescribing to 15 specialist centres
Efficacy was never the question in this appraisal. Duration of treatment was.
What changed at MKM in September, and what the company will not say about it
Documentation practice is the only part of vendor quality a buyer can assess before purchase.
India pharmacy body issues counselling standards for tirzepatide initiation
The evidence base is thin and the document says so, which is to its credit.
The quiet end of Calder Vale Peptides of Skipton
A proper account of an operation that existed, and of what closing it cost.
We split six vials four ways and posted them
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 the trials counted as intolerance
An effect is dose-limiting when it prevents adequate intake, prevents normal activity, or produces a risk of its own. Discomfort alone is not the test.
STEP 2 extension data: what happens after the trial stops
A design note rather than a result: what the comparator was, and what that permits you to conclude.
Poland caps tirzepatide prescribing to 22 specialist centres
Efficacy was never the question in this appraisal. Duration of treatment was.
What the new Australia guidance says about stopping
The evidence base is thin and the document says so, which is to its credit.
From the floor in Xi'an: 15 posters, one theme
Reported from the sessions, and from the two hours afterwards.
The shelf life ends when the diluent goes in
At low concentrations a measurable fraction of peptide can adsorb to glass and plastic surfaces, and the loss is largest exactly where it is least expected.
Retention time is not identity
Matching a retention time against a standard is evidence of consistency, not proof of identity. Two different species can elute at the same time on one method.
Homopeptide 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.
