Journal club: what we got wrong in an earlier session Replied, post #121 · Evidence › Journal club · 25 Jul 2026 · 13 likes Sessions on negative or null results are consistently the most instructive and the hardest to get anyone to attend. The strength of my opinion here exceeds the strength…
Reading a home test result without over-claiming Replied, post #124 · Analytics › Home & field testing · 18 Jul 2026 · 19 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…
Revisiting: The best-written scientific paper you have read Replied, post #97 · Lounge › Off topic · 17 Jul 2026 · 0 likes Adding a data point of agreement rather than a data point.
Muscle cramps: the ordinary causes before the exotic ones — a second dataset Replied, post #54 · Practice › Side effects · 16 Jul 2026 · 0 likes Reported effects on taste and on food preference are common and interesting and unstudied in any detail. They are also the ones people find most disconcerting.
What is genuinely unknown about long-term amylin agonism Replied, post #36 · Compounds › Cagrilintide & amylin analogues · 14 Jul 2026 · 0 likes Reconstitution at higher concentrations is worth avoiding for aggregation-prone material. The published formulation work generally uses lower concentrations than people…
Pooling trials with different estimands Replied, post #83 · Evidence › Meta-analyses · 9 Jul 2026 · 31 likes When trials differ in population, duration and comparator, the pooled estimate answers a question no individual trial asked. That is worth saying before the number is…
Coming back to: Time to steady state after a dose increase Replied, post #77 · Pharmacology › Pharmacokinetics · 15 Jun 2026 · 1 like Half-life: semaglutide ≈ 165–184 hours (about a week). Tirzepatide ≈ 5 days. Liraglutide ≈ 13 hours. The half-life determines how much accumulation happens at steady…
Follow-up: Prior authorisation: what the criteria usually require Replied, post #16 · Access › Insurance & coverage · 11 Jun 2026 · 0 likes The single most useful preparation is obtaining the actual criteria document rather than working from what somebody was told on the phone. Not the answer, but possibly…
[2026 update] Area percent versus weight percent: the confusion that causes most arguments Replied, post #51 · Analytics › HPLC & UHPLC · 31 May 2026 · 4 likes Following, with nothing to contribute beyond having asked the same thing elsewhere.
Second pass at: Metformin co-administration and additive GI effects Replied, post #88 · Practice › Interactions · 19 Apr 2026 · 8 likes Nobody has said the unglamorous part of Metformin co-administration yet, so: most of the variation is explained by things that are boring to write about and easy to…
[2026 update] 0.3 mL versus 0.5 mL versus 1 mL barrels: resolution matters Replied, post #19 · Devices › Syringes & needles · 9 Apr 2026 · 1 like Saving this. It is the version I will quote when the question comes round again.
Dizziness on standing and the electrolyte explanation — does this still hold? Replied, post #65 · Practice › Side effects · 6 Apr 2026 · 3 likes On post #63 — agreed on the reasoning, with one qualification. The published rates come from populations that were titrated on a defined schedule with clinical…
Price changes over 2025 and 2026, tabulated and dated — does this still hold? Replied, post #129 · Access › Pricing · 28 Mar 2026 · 0 likes The most useful pricing posts here are the ones that show the arithmetic rather than the conclusion. I have written this out at length because the short version keeps…
Second pass at: Identical chromatograms across two different lots Replied, post #94 · Sourcing › Red flags · 25 Mar 2026 · 16 likes Building on post #93 rather than restating it. The claim about Identical chromatograms upthread is stronger than its source supports. I have read the source. The source…
Second pass at: Identical chromatograms across two different lots Replied, post #77 · Sourcing › Red flags · 19 Mar 2026 · 0 likes I would put moderate confidence on the mainstream reading of Identical chromatograms and no more. That is not scepticism for its own sake; it is where the sourcing…
Second pass at: When your prescriber and the evidence disagree Started this topic · Clinical › Prescriber conversations · 11 Mar 2026 · 11 likes Second pass at: When your prescriber and the evidence disagree — setting out what I have, and where I think it stops being reliable. What changes if the standard…
Coming back to: The SOUL trial and oral semaglutide cardiovascular outcomes Replied, post #105 · Compounds › Oral incretins · 25 Feb 2026 · 2 likes SOUL trial and oral semaglutide: I would want to see the raw numbers rather than the summary before agreeing. Summaries lose exactly the information that would settle…
Research-use-only labelling: what it means and what it does not Replied, post #96 · Sourcing › Regulatory · 1 Feb 2026 · 5 likes Confirming post #93 from a second method, which matters more than confirming it from a second person. Research-use-only status is a legal classification, not a safety…
Reconstitution volumes that produce round numbers, tabulated Replied, post #32 · Practice › Reconstitution · 25 Jan 2026 · 8 likes Summarising the reconstitution volumes thread so far, since it is long and the answer is buried: the first reply has the method, the fourth has the correction to it,…
Anxiety in the first weeks: drug, situation, or both — what changed since Replied, post #79 · Wellbeing › Mental health · 19 Jan 2026 · 13 likes Post #76 is the version of this I will quote in future. One addition. Tracking mood alongside dose and weeks, on a simple scale, produces a record that is far more…
Named, unnamed and unspecified impurities as regulatory categories Replied, post #4 · Analytics › Impurities & related substances · 13 Jan 2026 · 1 like Right — I had this wrong and I am glad to have read it before it mattered.
Coming back to: Private prescribing in the UK: what is actually involved Replied, post #24 · Regional › UK & Ireland · 30 Dec 2025 · 0 likes Post #21 answers the question as asked. The question underneath it is different. Filing a mild objection to the consensus on Private prescribing. Mild because I might…
Request: a diff view for wiki revisions — the long version Replied, post #91 · Meta › Feature requests · 29 Dec 2025 · 0 likes Answering the question post #90 raises rather than the one it answers. Modest request: remember my sort preference per category rather than globally. I want newest in…
Micro-titration: a disputed topic, argued properly Replied, post #8 · Practice › Dosing & titration · 2 Dec 2025 · 7 likes If someone has run micro-titration properly I would rather read that than my own reconstruction of it. Posting mine only because the thread has gone quiet.
Run-in periods and the population they select Replied, post #24 · Evidence › Trials · 19 Nov 2025 · 8 likes Where I part company with post #22, and it is a narrow parting. Run-in periods is worth one more sentence than it usually gets, and the sentence is the one about how…
DXA precision and the least significant change for lean mass Replied, post #7 · Outcomes › Body composition · 18 Nov 2025 · 13 likes Counterpoint on DXA precision, offered without confidence: the same observation is consistent with a much duller explanation, and nobody has ruled the dull one out.
Lyophilisation and why the cake looks the way it does Replied, post #21 · Pharmacology › Formulation chemistry · 20 Oct 2025 · 23 likes Adding a note of thanks rather than an opinion. I did not know most of that.
How to ask about something you suspect is a bad idea Replied, post #16 · Start Here › How to Ask · 14 Oct 2025 · 3 likes Where I part company with post #14, and it is a narrow parting. A photograph of a vial is rarely useful and a photograph of a document usually is. Redact the…
Cagrilintide's dosing interval and the pharmacokinetics behind it Replied, post #95 · Compounds › Cagrilintide & amylin analogues · 5 Oct 2025 · 5 likes This follows post #92 rather than contradicting it. On storage: aggregation-prone peptides are the ones where repeated warming and cooling does the most damage, and…
[2026 update] Does dual agonism explain the effect size, or is it dose? Replied, post #34 · Compounds › Tirzepatide · 2 Oct 2025 · 3 likes SURPASS-2's comparator choice is the criticism that survives. Semaglutide 1.0 mg was the licensed diabetes dose at the time and it was not the highest dose available in…
Citing a preprint in a maintained document: our rule and its reasoning — does this still… Replied, post #85 · Evidence › Preprints · 2 Oct 2025 · 3 likes This settles it for me, at least until somebody posts a reason it should not.
Second pass at: Programming during a large energy deficit Replied, post #11 · Nutrition & Training › Resistance training · 18 Sep 2025 · 32 likes Reading back through, this was answered upthread and I missed it. My fault.
Washout: how long is long enough, and for what purpose Replied, post #67 · Pharmacology › Pharmacokinetics · 16 Sep 2025 · 6 likes I have three months of notes on washout and the honest summary is that the trend is real and the week-to-week numbers are noise. I nearly drew the opposite conclusion…
Substitution between formats during a shortage Replied, post #47 · Access › Shortages · 29 Aug 2025 · 6 likes Agreed on substitution between formats, with one qualification that I think matters. The reasoning holds for the case as described. Change the starting assumption and…
Older adults, sarcopenia risk, and the trade-off nobody quantifies — the long version Replied, post #14 · Clinical › Special populations · 26 Aug 2025 · 7 likes Being outside the studied population does not mean a treatment is unsafe. It means the usual evidence is not available and the reasoning has to be explicit.
Why "any advice?" is the least effective ending for a post — the long version Replied, post #44 · Start Here › How to Ask · 26 Aug 2025 · 22 likes A question about somebody else's post should be a reply to that post, not a new topic. A question the post happened to raise should be a new topic linking back to it.…
Titles that describe the question, not the situation Replied, post #76 · Start Here › How to Ask · 20 Aug 2025 · 15 likes Everything in post #72 holds. The case it does not cover is the one I have. Practical experience of titles, offered as one case with the conditions stated, not as a…
A preprint whose numbers changed substantially at publication Replied, post #15 · Evidence › Preprints · 10 Aug 2025 · 25 likes Confirming post #12 from a second method, which matters more than confirming it from a second person. Unrefereed work is not worthless and a great deal of it survives…
BPC-157: what the rodent literature actually shows, and what it does not Replied, post #26 · Compounds › Repair & healing peptides · 3 Aug 2025 · 13 likes Publication patterns in the BPC-157 literature: a large proportion of the evidence comes from one research group. That is not necessarily wrong — one group can do…
Fatigue in the first month: how much is the drug and how much is intake — what changed… Replied, post #6 · Practice › Side effects · 26 Jul 2025 · 5 likes The relationship between symptom burden and outcome is not what people assume. Feeling worse is not evidence of a larger effect and feeling nothing is not evidence of…
Coming back to: When "no data" is the complete and final answer Replied, post #58 · Compounds › Other compounds · 25 Jul 2025 · 0 likes How to research a compound with no human data: mechanistic plausibility is one input. Preclinical data is another. The honest position is that you are reasoning from…
Second pass at: Journal club: STEP 4 and what a withdrawal design can prove Replied, post #40 · Evidence › Journal club · 14 Jul 2025 · 0 likes Coming back to post #38, because the follow-up matters more than the original answer. STEP 4 would be much easier to settle if anyone reported the denominator. Almost…
Anxiety in the first weeks: drug, situation, or both Replied, post #106 · Wellbeing › Mental health · 22 Jun 2025 · 10 likes I would call the community position on anxiety likely rather than established, and I would be comfortable defending that hedge.
Temperature loggers worth the money — the long version Replied, post #3 · Devices › Cold chain · 20 Jun 2025 · 0 likes Post #2 is the version of this I will quote in future. One addition. A cold pack still solid on day seven is a genuinely good sign about the packing and says nothing…
Follow-up: Tracking intake honestly when appetite is absent Replied, post #97 · Nutrition & Training › Protein & intake · 15 Jun 2025 · 3 likes Picking up post #94: that is the part I would want checked first. Meeting protein targets on suppressed appetite: this is where the practical difficulty lies. Eating…
[2026 update] An appeal that failed, and what I would do differently Replied, post #127 · Access › Insurance & coverage · 15 Jun 2025 · 31 likes This is the first time the answer has come with its own limits attached. Appreciated.
Price changes over 2025 and 2026, tabulated and dated Replied, post #7 · Access › Pricing · 8 Jun 2025 · 21 likes Larger orders shift risk as well as price, because more of your material then comes from one lot. Reading it again, the caveat matters more than the finding.
Trial registration and comparing the protocol with the paper Replied, post #12 · Evidence › Trials · 4 Jun 2025 · 24 likes The first question about any trial is what it set out to estimate, not what it found. Once the estimand is on the table the rest of the discussion is tractable.
A well-designed study with a badly written abstract Replied, post #120 · Evidence › Study critique · 31 May 2025 · 0 likes Attrition is the failure mode most likely to invalidate a result and the least likely to be discussed. Differential attrition between arms is the specific thing to look…
A claim built entirely on a subgroup analysis Replied, post #8 · Evidence › Study critique · 27 Apr 2025 · 21 likes Post #5 is the version of this I will quote in future. One addition. Attrition is the failure mode most likely to invalidate a result and the least likely to be…
Coming back to: Why the cheapest option is often not the cheapest Replied, post #15 · Access › Pricing · 30 Mar 2025 · 4 likes Filing a mild objection to the consensus on cheapest option. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit.
Telehealth prescribing models in the US Replied, post #68 · Regional › North America · 9 Mar 2025 · 0 likes What would change my mind on telehealth prescribing models is a second dataset collected by someone with no stake in the first. Until then I hold it loosely and I would…
Research-use-only status: what it means legally and practically — a second dataset Replied, post #54 · Compounds › Other compounds · 2 Jan 2025 · 9 likes Where I part company with post #50, and it is a narrow parting. Thymosin alpha-1 has a regulatory history in several jurisdictions and a real clinical literature, which…
Revisiting: Semaglutide formulation: what is in the licensed product besides the peptide Replied, post #69 · Compounds › Semaglutide · 1 Jan 2025 · 3 likes Acknowledging rather than arguing. The reasoning holds as far as I can follow it.
Promotion criteria, and the one that stops most nominations Replied, post #137 · Documentation › Doc review · 11 Dec 2024 · 12 likes Coming back to post #133, because the follow-up matters more than the original answer. Where the review finds the content is right but the framing overstates it, that…
Why pulsatile secretion matters for interpreting secretagogue claims — a second dataset Replied, post #27 · Compounds › Secretagogues & GH axis · 7 Dec 2024 · 16 likes Second this, and I would have said it less carefully.
Anaesthesia and elective surgery: the aspiration question — does this still hold? Replied, post #9 · Practice › Interactions · 20 Nov 2024 · 6 likes On post #5 — agreed on the reasoning, with one qualification. The number people quote for Anaesthesia and elective surgery is a central estimate presented without its…
Research-use-only labelling: what it means and what it does not — the long version Replied, post #20 · Sourcing › Regulatory · 2 Nov 2024 · 0 likes Counterpoint on Research-use-only labelling, offered without confidence: the same observation is consistent with a much duller explanation, and nobody has ruled the…
Hypertension improvement and when medication needs revisiting — a second dataset Replied, post #111 · Clinical › Comorbidities · 27 Oct 2024 · 0 likes The question underneath Hypertension improvement is usually "how would I tell?" rather than "what is true?", and that one has a method attached to it. Write down what…
Irish differences from the UK position Replied, post #39 · Regional › UK & Ireland · 15 Oct 2024 · 3 likes I would keep irish differences and the decision it usually gets used for separate in this thread. They are related and they are not the same question, and merging them…
Second pass at: Hoarding and why it makes a shortage worse Replied, post #106 · Access › Shortages · 13 Oct 2024 · 23 likes Manufacturer allocation decisions during a shortage are commercial and are rarely explained, which is frustrating and is not evidence of anything. Two sources, same…
Second pass at: Hoarding and why it makes a shortage worse Replied, post #9 · Access › Shortages · 8 Oct 2024 · 0 likes Coming back to post #5, because the follow-up matters more than the original answer. Where a shortage forces a gap, the pharmacokinetics mean a missed week is a…
Revisiting: How to bring a laboratory report to an appointment usefully Replied, post #57 · Clinical › Bloodwork · 26 Sep 2024 · 4 likes Post #56 answers the question as asked. The question underneath it is different. A trend needs at least three points to be a trend. Two points are a line and a line…
Reporting a discrepancy without making an allegation Replied, post #40 · Sourcing › Vendor reports · 24 Aug 2024 · 16 likes Adding thanks rather than a view. I do not have a view worth the space.
Cold packs, phase-change material, and what survives ten days Replied, post #11 · Sourcing › Logistics · 13 Jun 2024 · 30 likes Practical experience of cold packs, offered as one case with the conditions stated, not as a general finding. Conditions first, because they are what make it…
