Stepping down deliberately, and how to do it without losing progress — what changed since Replied, post #90 · Practice › Dosing & titration · 23 Jul 2026 · 22 likes Holding a dose indefinitely: the trials did not study indefinite holding at a non-maximum dose. The trials escalated to a target and then held that. What happens if you…
Spreadsheets: an appreciation — what changed since Replied, post #109 · Lounge › Off topic · 22 Jul 2026 · 1 like Picking up post #106: that is the part I would want checked first. Politics and public policy: healthcare policy that affects access to these compounds is relevant…

Tracking a shortage from primary sources rather than rumour Replied, post #93 · Access › Shortages · 9 Jul 2026 · 22 likes post #92 is right about the mechanism and I think understates the practical bit. International supply chains: a shortage in one country does not mean shortage in…
Carryover and the ghost peak from last week's standard — what changed since Replied, post #87 · Analytics › HPLC & UHPLC · 29 Jun 2026 · 3 likes On integration: where the baseline is drawn matters more than most people realise.

Coming back to: Measurement error in a self-reported exposure Replied, post #28 · Evidence › Study critique · 29 Apr 2026 · 3 likes Criticise the method, not the author: a paper with a weak design is not a bad paper by someone with bad intentions. It is a paper that answers a limited question.…
[2026 update] Composite endpoints and the component doing the work Replied, post #88 · Evidence › Trials · 27 Apr 2026 · 12 likes Multiplicity and multiple comparisons: if a trial tests many hypotheses, the chance of a false positive on at least one by random chance increases. This is why…

Follow-up: State-level differences that actually matter Replied, post #96 · Regional › North America · 9 Apr 2026 · 19 likes Canada: Health Canada licenses compounds. Prescribing is provincial. Compounds are prescription-only. Coverage varies between public and private insurance.
Documenting a payment dispute without naming and shaming Replied, post #6 · Sourcing › Payments · 6 Apr 2026 · 27 likes Bank transfer and finality: once a bank transfer is sent, it is final. The money is gone. There is no recourse with the bank if the supplier disappears. That is why…

Seven-day rolling means and why weekly readings mislead — one year on Replied, post #43 · Outcomes › Progress reports · 12 Feb 2026 · 0 likes Protein intake and resistance training: both self-reported and therefore optimistic in most reports.
