Coming back to: Why our vendor pages link the storefront and mark it sponsored Replied, post #3 · Sourcing › Vendor reports · 28 Jul 2026 · 3 likes Blind submission is worth the extra effort. Have someone else relabel the sample so neither you nor the laboratory knows the origin until the result is back.

[2026 update] Travelling with an injectable: documentation and practicalities Replied, post #111 · Access › International · 26 Jul 2026 · 0 likes Summaries lag badly in this area. Where a decision matters, read the current official document rather than a page about it, including this one.

Coming back to: Where the four-week escalation interval comes from, and what it is not Replied, post #45 · Practice › Dosing & titration · 25 Jul 2026 · 0 likes Building on post #43 rather than restating it. Titrating on tolerability rather than on the calendar: some people escalate when they tolerate a dose well, others…

Follow-up: How compounding permissions changed when supply normalised Replied, post #52 · Sourcing › Regulatory · 21 Jul 2026 · 18 likes What I would want before treating compounding permissions as settled: the method, the sample, and whether anyone tried to find the opposite result. Two of the three are…

Second pass at: Absence of evidence and evidence of absence Replied, post #50 · Research Methods › Statistics · 20 Jul 2026 · 4 likes Effect sizes: the magnitude of a difference, not just whether it is statistically significant. A difference that is significant (p

[2026 update] Antibiotics and a course of something with delayed emptying Replied, post #61 · Practice › Interactions · 19 Jul 2026 · 4 likes Narrowing post #60, because the general version has more than one answer. Two sentences on Antibiotics and then I will stop, because the rest is speculation and the…

Insurance and replacement policies, compared Replied, post #99 · Sourcing › Logistics · 18 Jul 2026 · 22 likes Post #96 describes the usual case. This is about the unusual one. Anyone deciding whether a delay is a problem should ask what would change if they waited another week.…

Coming back to: Delayed gastric emptying and oral medication absorption: which drugs… Replied, post #34 · Practice › Interactions · 17 Jul 2026 · 25 likes Post #30 and I disagree about the size of the effect, not about the direction. A methods point on Delayed gastric emptying and oral rather than a substantive one: if…

Journal club: orforglipron phase 2 and the non-peptide question Replied, post #121 · Evidence › Journal club · 15 Jul 2026 · 14 likes The failure mode on orforglipron phase 2 is boring rather than dramatic. It is almost always the step everyone assumes was done correctly because it is too simple to…

Primary endpoint hierarchies and why order matters — one year on Replied, post #46 · Evidence › Trials · 14 Jul 2026 · 13 likes Subgroup analyses are hypothesis-generating unless pre-specified and adequately powered, and almost none are the second. The interaction test matters more than the…

Common supplements people ask about, assessed one at a time Replied, post #44 · Practice › Interactions · 14 Jul 2026 · 32 likes Marking my uncertainty on common supplements explicitly. I am confident about the direction, much less confident about the size, and not confident at all that it…

What I would want from a home test that does not exist yet — what changed since Replied, post #93 · Analytics › Home & field testing · 14 Jul 2026 · 1 like Coming back to post #91, because the follow-up matters more than the original answer.
