Reconstituted…
Blinding yourself: practical methods and their limits Replied, post #42 · Research Methods › N-of-1 designs · 13 Jul 2026 · 12 likes I read post #41 twice before replying, because I had assumed the opposite. Trying to state the blinding yourself position in a way that someone who disagrees would…
What I would want from a home test that does not exist yet Replied, post #33 · Analytics › Home & field testing · 10 Jul 2026 · 0 likes Where a home observation and an independent result disagree, the independent one is measuring something more specific.

Seven-day rolling means and why weekly readings mislead Replied, post #6 · Outcomes › Progress reports · 10 Jul 2026 · 0 likes Confirming post #5 from a second method, which matters more than confirming it from a second person. The best progress reports here read as records rather than as…

Allergy to the specific compound: true allergy is rare but possible. Any prior allergic reaction…

Follow-up: Signs of dehydration worth acting on Replied, post #12 · Safety › Adverse events · 3 Jul 2026 · 0 likes The reason Signs of dehydration worth acting keeps being re-asked is that the answer is conditional and people quote it without the condition. It is not that the answer…
Revisiting: Can a home kit substitute for a laboratory report? A careful no Replied, post #39 · Analytics › Home & field testing · 23 Jun 2026 · 1 like Ultraviolet absorbance at 280 nanometres estimates concentration for peptides containing aromatic residues and gives nothing for peptides that do not. Knowing which…
Ultrasound and skinfolds: operator dependence in practice Replied, post #21 · Outcomes › Body composition · 18 Jun 2026 · 0 likes Post #19 and I disagree about the size of the effect, not about the direction. Bone mineral density changes with substantial weight loss are measurable and slow, and…
