Second pass at: Cost versus information: making the trade-off explicitly Replied, post #28 · Analytics › Home & field testing · 27 Jul 2026 · 1 like Reconstitution behaviour is a legitimate home observation. A cake that will not dissolve, a solution that hazes, visible particulate — all are real information and all…
Coming back to: Lateral-flow and colorimetric approaches: the specificity problem Replied, post #86 · Analytics › Home & field testing · 24 Jul 2026 · 28 likes Colorimetric tests: colour intensity correlates with concentration, but the relationship is non-linear at extremes and the correlation depends on the exact conditions…
[2026 update] Travelling with an injectable: documentation and practicalities Replied, post #101 · Access › International · 22 Jul 2026 · 2 likes Post #100 answers the question as asked. The question underneath it is different. Currency and exchange rates: paying in different currencies has different costs and…
Restarting after a long gap: what the labelling implies Replied, post #34 · Practice › Dosing & titration · 20 Jul 2026 · 0 likes Doubling after a miss adds a peak for no gain and is not what any labelling in this class recommends. That is a description of the labelling rather than advice about…
Follow-up: Signs of dehydration worth acting on Replied, post #24 · Safety › Adverse events · 14 Jul 2026 · 20 likes Medullary thyroid carcinoma is the reason these compounds are contraindicated in people with personal or family history of MTC or multiple endocrine neoplasia type 2.…
What I would want from a home test that does not exist yet Replied, post #27 · Analytics › Home & field testing · 4 Jul 2026 · 32 likes Sample handling matters: if a sample is contaminated or degraded before testing, the test gives you the result for the degraded sample, not for fresh material. That is…
Selection into a registry and what it does to the estimate — a second dataset Replied, post #5 · Evidence › Study critique · 1 Jul 2026 · 0 likes Narrowing post #4, because the general version has more than one answer. Selection is a question about a distribution, not about a value, and treating it as a value is…
What steady state means for the decision to escalate Replied, post #20 · Practice › Dosing & titration · 28 Jun 2026 · 6 likes Concentration and dose get conflated constantly in this subcategory. Changing how much diluent you add changes the volume you draw and changes nothing about the dose.
Racemisation and why it is invisible to a mass measurement Replied, post #128 · Analytics › Impurities & related substances · 15 Jun 2026 · 14 likes Building on post #127 rather than restating it. Incomplete deprotection leaves a protecting group attached, raising the mass substantially and usually pushing retention…
Why cagrilintide alone is discussed so much less than in combination — does this still… Replied, post #9 · Compounds › Cagrilintide & amylin analogues · 15 Jun 2026 · 10 likes My position on cagrilintide alone is current rather than settled. I have revised it once already and I expect to again, so treat it accordingly.
Ultrasound and skinfolds: operator dependence in practice Replied, post #11 · Outcomes › Body composition · 9 Jun 2026 · 0 likes Where I have landed on ultrasound and skinfolds, having got it wrong once in public: the direction is clear, the magnitude is not, and anyone quoting a precise…
Why fasting instructions for oral semaglutide are not optional advice Replied, post #14 · Compounds › Oral incretins · 25 May 2026 · 3 likes Post #12 and I disagree about the size of the effect, not about the direction. Trial adherence in an oral trial with strict administration requirements is genuinely…
