Follow-up: Signs of dehydration worth acting on Replied, post #36 · Safety › Adverse events · 24 Jul 2026 · 8 likes The published trial rates come from supervised populations on defined schedules and are not comparable to rates derived from who chooses to post.
Follow-up: How compounding permissions changed when supply normalised Replied, post #59 · Sourcing › Regulatory · 23 Jul 2026 · 2 likes Narrowing post #57, because the general version has more than one answer. The confident answers on compounding permissions and the well-sourced answers are not the same…
[2026 update] Regional warehouse stock versus direct despatch Replied, post #142 · Sourcing › Logistics · 21 Jul 2026 · 24 likes Worth stating the null on Regional warehouse stock versus direct before we explain it: the observation may be nothing. That possibility deserves a sentence and usually…
[2026 update] Detection wavelength and why 214 nm and 280 nm disagree Replied, post #45 · Analytics › HPLC & UHPLC · 17 Jul 2026 · 6 likes Counterpoint on Detection wavelength, offered without confidence: the same observation is consistent with a much duller explanation, and nobody has ruled the dull one…

Second pass at: Absence of evidence and evidence of absence Replied, post #41 · Research Methods › Statistics · 9 Jul 2026 · 3 likes Absence of statistical significance is not evidence of absence, particularly in a small study. The width of the interval tells you what was ruled out and the p-value…
What a certificate commits its issuer to Replied, post #7 · Analytics › COA interpretation · 9 Jul 2026 · 10 likes Endotoxin testing is separate: a certificate of purity says nothing about endotoxin. A chemically pure preparation can carry a clinically significant endotoxin load. If…
Revisiting: Protein density versus volume when you cannot eat much Replied, post #40 · Nutrition & Training › Protein & intake · 7 Jul 2026 · 0 likes Where somebody reports losing strength, intake and training stimulus are the first two things to look at rather than the compound.
Prescription portability between countries Replied, post #88 · Access › International · 5 Jul 2026 · 32 likes Post #85 answers the question as asked. The question underneath it is different. On prescription portability between countries: the maintained page in the documentation…
Coming back to: A community side-effect dataset, with its response rate and biases Replied, post #90 · Data & Tools › Datasets · 3 Jul 2026 · 1 like I would put moderate confidence on the mainstream reading of community side-effect dataset and no more.
