Request: tag synonyms surfaced in search Replied, post #26 · Meta › Feature requests · 25 Jul 2026 · 7 likes Worth separating two things that post #22 runs together. I would use that constantly. The objection is presumably that it is data the site then has to hold and protect…
Journal club: SUSTAIN 6 and its retinopathy signal Replied, post #115 · Evidence › Journal club · 25 Jul 2026 · 5 likes Reading rather than contributing, but this is the most useful thread I have found on it.
Talking to a therapist about this specifically Replied, post #22 · Wellbeing › Mental health · 18 Jul 2026 · 5 likes I read post #20 twice before replying, because I had assumed the opposite. The social side of this — how other people respond to visible change — comes up constantly…
Molecular mass of semaglutide and why the figure differs between sources Replied, post #103 · Compounds › Semaglutide · 17 Jul 2026 · 13 likes Semaglutide's structure is a modified backbone with a C18 diacid attached through a spacer. The acylation is the reason for the long half-life and it is also the reason…
What a reversed-phase purity number actually is Replied, post #60 · Analytics › HPLC & UHPLC · 16 Jul 2026 · 0 likes Reversed-phase purity number came up in a thread eighteen months ago and was answered well. I cannot find it, which is itself the problem, so here is the reconstruction.

Ultrasound and skinfolds: operator dependence in practice Replied, post #44 · Outcomes › Body composition · 5 Jul 2026 · 9 likes Post #41 is the version of this I will quote in future. One addition. Percentage body fat is a ratio, so it changes when either component changes. A rising percentage…
Completing a dose with a second syringe, and the dead-volume arithmetic Replied, post #61 · Practice › Administration · 26 Jun 2026 · 22 likes Air in the syringe is a much smaller problem subcutaneously than the anxiety about it suggests, and it is still worth expelling because the bubble occupies volume you…
Journal club: SELECT, absolute risk, and how it was reported Replied, post #3 · Evidence › Journal club · 23 Jun 2026 · 1 like Coming back to the opening post, because the follow-up matters more than the original answer. Critical appraisal template: (1) What did the trial set out to estimate?…
A supplier who responds to a discrepancy with silence — what changed since Replied, post #66 · Sourcing › Red flags · 19 Jun 2026 · 0 likes Building on post #63 rather than restating it. Supplier is one of those subjects where the general answer and the answer for a specific case diverge, and the thread…
Does dual agonism explain the effect size, or is it dose? Replied, post #43 · Compounds › Tirzepatide · 18 Jun 2026 · 8 likes I read post #39 twice before replying, because I had assumed the opposite. Dual agonism: I have looked for the primary source twice and failed twice. Either it does not…
Why we ask for units every single time, with three examples of what goes wrong Replied, post #16 · Start Here › How to Ask · 3 Jun 2026 · 4 likes A photograph of a vial is rarely useful and a photograph of a document usually is.
