Revisiting: The best-written scientific paper you have read Replied, post #108 · Lounge › Off topic · 22 Jul 2026 · 5 likes Source for the best-written scientific paper figure, since it was asked for. It is in the discussion rather than the abstract, which is why the version circulating is…
Prior authorisation: what the criteria usually require — a second dataset Replied, post #50 · Access › Insurance & coverage · 21 Jul 2026 · 0 likes Counterpoint on Prior authorisation, offered without confidence: the same observation is consistent with a much duller explanation, and nobody has ruled the dull one out.
[2026 update] Detection wavelength and why 214 nm and 280 nm disagree Replied, post #52 · Analytics › HPLC & UHPLC · 20 Jul 2026 · 17 likes Small correction to my own earlier position on Detection wavelength.

Tracking semaglutide's approved indications across jurisdictions, dated Replied, post #18 · Compounds › Semaglutide · 18 Jul 2026 · 4 likes Post #16 and I disagree about the size of the effect, not about the direction.

Purity and identity are different questions: LC-MS establishes that the species at a retention…
Reading a home test result without over-claiming Replied, post #120 · Analytics › Home & field testing · 15 Jul 2026 · 21 likes A home refractometer is not measuring what people hope it is measuring in these preparations, and the readings are dominated by everything other than the peptide.…
A structured critique template this community uses Started this topic · Evidence › Study critique · 15 Jul 2026 · 7 likes A structured critique template this community uses — setting out what I have, and where I think it stops being reliable. Structured critique template — I have the…
Constipation management, with a dietitian's contribution Replied, post #89 · Practice › Side effects · 7 Jul 2026 · 0 likes The arithmetic in post #87 is right; the assumption feeding it is the part to check. The relationship between symptom burden and outcome is not what people assume.…
What to bring: records that a clinician can actually use — a second dataset Replied, post #10 · Clinical › Prescriber conversations · 6 Jul 2026 · 2 likes Building on post #9 rather than restating it. Prescription logistics: confirm whether it will be filled locally, requires mail order, or will be prescribed off-label…
What I would want from a home test that does not exist yet Replied, post #23 · Analytics › Home & field testing · 29 Jun 2026 · 24 likes Post #19 and I disagree about the size of the effect, not about the direction. Immunoassay limitations: tests that use antibodies have cross-reactivity limitations. An…
Journal club: LEADER as the historical anchor Replied, post #90 · Evidence › Journal club · 16 Jun 2026 · 0 likes Confirming post #88 from a second method, which matters more than confirming it from a second person. A note on how LEADER gets discussed rather than on LEADER itself:…
