Maximum tolerated is not maximum approved
Weight reduction in the long programmes flattens at roughly sixty to seventy-two weeks. The timing is consistent, predictable and almost never mentioned in advance.
Explainers
For readers arriving new: what these drugs are, how they are given, what the words on the label mean, and how to tell a measurement from a marketing claim. Written to be read once.
Everything filed here
What the anaesthetists said, and then said again
This is the single interaction with ordinary medical care that patients most need to disclose, and it is the one most often not asked about.
The restart nobody plans for
The convention — resume lower, re-escalate — is not caution. It follows directly from the elimination half-life.
Background rates, and why they matter for attribution
Pancreatitis is rare, was adjudicated in the outcome programmes, and did not show the imbalance early case reports suggested.
Why a 0.036-dalton difference is the hardest number in peptide identity
Every instrument specification quoted in an advertisement is a best case obtained on a calibration mixture, not on a submitted vial.
Disregard limits: what a regulated laboratory does with a tiny peak
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.
GIP was a failed target for thirty years. Then it was not.
What adding GIP activity does, on the current evidence, and what remains unresolved.
Steady state is not a metaphor — it is an arithmetic fact about exenatide
What the pharmacokinetic data supports about dose timing, missed doses and interruption.
Peak capacity, and the honest measure of a separation
Gradient slope is the single most consequential method parameter for a reported purity figure, and it is the one most often omitted.
The eighteenth month, and the conversation that should have happened in the third
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.
The specification sheet says 500,000. The report says conforms.
Every instrument specification quoted in an advertisement is a best case obtained on a calibration mixture, not on a submitted vial.
What orthogonal actually means, and what it does not
Aggregates dissociate in the mobile phase and are recorded as monomer. Only a size-based separation reports them.
Adverse events by dose, adverse events by week
Trial adverse-event tables count episodes reported to a study nurse. They are the best data we have and they systematically under-record the mundane.
Where the receptor is: a tissue-by-tissue account of liraglutide’s reach
The central effects are not a bonus. On the current evidence they are the principal mechanism of weight loss.
Choosing a needle for a subcutaneous peptide
Skin thickness at the standard injection sites is approximately two millimetres in adults and varies remarkably little with body mass. That single finding is why short…
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.
Dose-limiting: a definition worth being strict about
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.
Gastric emptying is a mechanism, not a side effect
The central effects are not a bonus. On the current evidence they are the principal mechanism of weight loss.
How a release document is put together in a regulated plant
Nothing on this page is difficult. It is simply unfamiliar, and unfamiliarity is what makes a weak certificate look like a strong one.
Reading a barrel: the graduation that is not the one you think
The graduation interval differs between barrel sizes, and a 1 mL barrel is frequently marked in two-unit steps. Reading one as though it were marked in single units halves…
