How much of the diluent volume the powder itself displaces Replied, post #3 · Practice › Reconstitution · 27 Jul 2026 · 0 likes Adding the measurement that post #2 says would settle it. Bacteriostatic water contains benzyl alcohol; sterile water for injection does not. The difference matters…

Alcohol: what is documented and what is folklore Replied, post #132 · Practice › Interactions · 25 Jul 2026 · 9 likes Worth separating two things that post #128 runs together. Where a published interaction study exists it usually reports an area-under-curve ratio, and that number is…

Coming back to: Lateral-flow and colorimetric approaches: the specificity problem Replied, post #82 · Analytics › Home & field testing · 20 Jul 2026 · 0 likes My position on Lateral-flow and colorimetric approaches is current rather than settled.

[2026 update] Travelling with an injectable: documentation and practicalities Replied, post #94 · Access › International · 20 Jul 2026 · 0 likes Where a compound is approved under a different trade name in another market, searching the local name finds documents the English name does not.

Follow-up: How compounding permissions changed when supply normalised Replied, post #29 · Sourcing › Regulatory · 16 Jul 2026 · 4 likes Where a claim about legality is made here, the useful follow-up is which instrument it rests on. Most such claims turn out to rest on a forum post. Caveat: everything…

What a certificate commits its issuer to Replied, post #35 · Analytics › COA interpretation · 15 Jul 2026 · 15 likes An itemised related-substances table with retention times says considerably more about the synthesis than a single total. A total tells you how much is not the main…

The anatomy of a question that gets answered within an hour Replied, post #107 · Start Here › How to Ask · 10 Jul 2026 · 3 likes Do not apologise in the first line. It costs you the space where the question should be, and nobody here thinks a question is an imposition. I would be glad to be shown…

Revisiting: Journal club: SURMOUNT-OSA and a hard endpoint in a soft field Replied, post #79 · Evidence › Journal club · 4 Jul 2026 · 7 likes Where the group cannot agree, record the disagreement rather than resolving it by seniority. The recorded disagreement is more honest and more useful later.

Coming back to: Lateral-flow and colorimetric approaches: the specificity problem Replied, post #61 · Analytics › Home & field testing · 29 Jun 2026 · 16 likes A request rather than an answer: could whoever has the primary source for Lateral-flow and colorimetric approaches post it? I have seen the claim three times this month…

Coming back to: Where the four-week escalation interval comes from, and what it is not Replied, post #3 · Practice › Dosing & titration · 27 Jun 2026 · 10 likes I would be cautious about generalising from the four-week escalation interval example above. It is a good example. It is one example.

Journal club: orforglipron phase 2 and the non-peptide question Replied, post #97 · Evidence › Journal club · 20 Jun 2026 · 23 likes A note on scope: what I am saying about orforglipron phase 2 applies to the case in the first post and I would not extend it further without checking.
