Alcohol: what is documented and what is folklore Replied, post #134 · Practice › Interactions · 26 Jul 2026 · 0 likes Adding a reference point for alcohol. Mine is a single case, collected without controls, and I am posting the method alongside it so it can be discounted appropriately.
Revisiting: The best-written scientific paper you have read Replied, post #110 · Lounge › Off topic · 23 Jul 2026 · 20 likes Best-written scientific paper has been discussed here with more heat than it deserves, mostly because two definitions have been in play the whole time.
Second pass at: What a 2 ppm match establishes, and what it does not Replied, post #47 · Analytics › Mass spectrometry · 21 Jul 2026 · 1 like Where the 2 ppm match reasoning breaks down for me is the step from the group result to the individual case. That step is almost never argued for.
A pooled estimate that changed when one trial was added Replied, post #26 · Evidence › Meta-analyses · 20 Jul 2026 · 6 likes Picking up post #23: that is the part I would want checked first. When a meta-analysis is unhelpful: if the included studies are heterogeneous in population,…
What a certificate commits its issuer to Replied, post #37 · Analytics › COA interpretation · 15 Jul 2026 · 1 like Reading old certificates: if a certificate is dated years ago, the lot it describes might be old. That is not automatically a problem but it is worth noting. Fresh…

What is not established is whether the tolerability profile differs from…
The anatomy of a question that gets answered within an hour Replied, post #105 · Start Here › How to Ask · 8 Jul 2026 · 24 likes This follows post #102 rather than contradicting it. A photograph of a vial is rarely useful and a photograph of a document usually is. Redact the identifiers before…
Tracking a shortage from primary sources rather than rumour Replied, post #79 · Access › Shortages · 1 Jul 2026 · 2 likes Post #78 is right about the mechanism and I think understates the practical bit. Planning around a known shortage window is easier than reacting to one, and the notices…
Common supplements people ask about, assessed one at a time Started this topic · Practice › Interactions · 30 Jun 2026 · 5 likes Common supplements people ask about, assessed one at a time — setting out what I have, and where I think it stops being reliable. A follow-up question about common…
What I would want from a home test that does not exist yet Replied, post #21 · Analytics › Home & field testing · 27 Jun 2026 · 3 likes Research-use-only material is not certified for anything by anybody, and no home procedure changes that. What home checks buy you is early detection of the obvious…
Reading a home test result without over-claiming Replied, post #89 · Analytics › Home & field testing · 22 Jun 2026 · 3 likes Research-use-only material is not certified for anything by anybody, and no home procedure changes that. What home checks buy you is early detection of the obvious…
Ultrasound and skinfolds: operator dependence in practice Replied, post #13 · Outcomes › Body composition · 11 Jun 2026 · 7 likes Adding the boring version of ultrasound and skinfolds, because the interesting version keeps getting posted and the boring one is usually right. Check the ordinary…
