Named, unnamed and unspecified impurities as regulatory categories — the long version Replied, post #115 · Analytics › Impurities & related substances · 26 Jul 2026 · 18 likes Aggregates: multiples of the monomer mass.

Muscle cramps: the ordinary causes before the exotic ones — a second dataset Replied, post #75 · Practice › Side effects · 25 Jul 2026 · 1 like Coming back to post #71, because the follow-up matters more than the original answer.

Reading U-100 graduations, with a conversion table Replied, post #41 · Devices › Syringes & needles · 22 Jul 2026 · 21 likes Sharps containers are a legal requirement for disposal in several jurisdictions and a sensible precaution everywhere. A rigid sealed container is the minimum. Happy to…

Revisiting: The report format the maintainers ask for, and why each field is there Replied, post #103 · Sourcing › Vendor reports · 17 Jul 2026 · 32 likes Photograph the vial and the label before opening.

Request: a per-category review queue Replied, post #85 · Meta › Feature requests · 7 Jul 2026 · 0 likes Per-category review queue looks different depending on whether you are reading the primary literature or the summaries of it, and the difference is not in our favour.

How much context is too much context in a first post? Replied, post #22 · Start Here › How to Ask · 6 Jul 2026 · 19 likes Adding the measurement that post #21 says would settle it. When you quote a figure from somewhere else, say where from. Not as a formality — the answer frequently…

A single out-of-range value on an otherwise normal panel Replied, post #67 · Clinical › Bloodwork · 2 Jul 2026 · 9 likes Rate of change is frequently more informative than absolute value, and it is only available if the earlier results were kept. Two sources, same conclusion, and I could…

Pages past their review date, listed — does this still hold? Replied, post #19 · Meta › Wiki maintenance · 20 Jun 2026 · 0 likes Adding what did not work for me on Pages past, since the failures never get written up and they are half the useful information.
