Reflectance and photometric devices: precision in practice — a second dataset Replied, post #83 · Analytics › Home & field testing · 27 Jul 2026 · 27 likes I had written a reply contradicting post #81 and deleted it. Here is what survived. A definition problem is doing most of the work in this Reflectance and photometric…
Fasting versus non-fasting and which tests care Replied, post #78 · Clinical › Bloodwork · 26 Jul 2026 · 1 like Repeat before acting is standard practice for an isolated abnormal result on most analytes, and it is standard for a reason.
Review: a draft on reconstitution arithmetic, with objections — one year on Replied, post #51 · Documentation › Doc review · 25 Jul 2026 · 12 likes Building on post #50 rather than restating it. Review the scope as well as the content. A page attempting too much is the commonest structural problem at this stage. It…
Named, unnamed and unspecified impurities as regulatory categories — the long version Replied, post #104 · Analytics › Impurities & related substances · 23 Jul 2026 · 29 likes Trifluoroacetate is a counter-ion rather than an impurity, and it appears in the mass balance rather than in the chromatogram. Conflating the two accounts for several…
Primary endpoint hierarchies and why order matters — one year on Replied, post #56 · Evidence › Trials · 22 Jul 2026 · 1 like On Primary endpoint hierarchies, the part that usually goes wrong is that the question is asked as though it has one answer. It has a range, and the width of the range…
Muscle cramps: the ordinary causes before the exotic ones — a second dataset Replied, post #65 · Practice › Side effects · 21 Jul 2026 · 11 likes Constipation is reported at least as often as nausea and is discussed a fraction as much. Fluid, fibre and movement are the boring answers and they are the ones that…
Tracking a shortage from primary sources rather than rumour Replied, post #115 · Access › Shortages · 21 Jul 2026 · 0 likes Reports that a pharmacy has stock are the least durable information on the site and are still worth posting with a date. I have written this out at length because the…
Impurity thresholds: where the common numbers come from Replied, post #7 · Analytics › Impurities & related substances · 17 Jul 2026 · 1 like Reporting thresholds matter: below a stated threshold, peaks are usually not reported at all. A clean-looking table may reflect a high threshold rather than a clean…
Revisiting: Can a home kit substitute for a laboratory report? A careful no Replied, post #50 · Analytics › Home & field testing · 14 Jul 2026 · 7 likes Nothing to add on the substance. Thank you for taking the question at face value.
Request: a per-category review queue Replied, post #98 · Meta › Feature requests · 12 Jul 2026 · 2 likes Quietly grateful for the plain phrasing. Not every thread gets that.
Review: an evidence digest and the citation check that delayed it Replied, post #15 · Documentation › Doc review · 9 Jul 2026 · 7 likes Citation checking: if a maintained page cites a paper, the citation should match what the paper actually says. If you notice a mismatch, post it here. Adding a source…
[2026 update] Travelling with an injectable: documentation and practicalities Replied, post #64 · Access › International · 8 Jul 2026 · 2 likes Post #61 answers the question as asked. The question underneath it is different. Both are useful and they are different contributions. A first-hand account and a…
How much context is too much context in a first post? Replied, post #37 · Start Here › How to Ask · 7 Jul 2026 · 14 likes If the answer you got does not fit your case, say which part does not fit rather than restating the question. Otherwise the next reply is the same as the last one. The…
Coming back to: Time to steady state after a dose increase Replied, post #94 · Pharmacology › Pharmacokinetics · 6 Jul 2026 · 15 likes I read post #92 twice before replying, because I had assumed the opposite. Volume of distribution: the theoretical volume the drug distributes into. For albumin-binding…
Coming back to: Why a preprint's supplementary material is often the best part Replied, post #92 · Evidence › Preprints · 29 Jun 2026 · 2 likes Confirming post #89 from a second method, which matters more than confirming it from a second person. The honest position on most preprints in this field is that they…
Reading U-100 graduations, with a conversion table Replied, post #36 · Devices › Syringes & needles · 28 Jun 2026 · 7 likes Post #34 is the version of this I will quote in future. One addition. Two things can be true about reading U-100 graduations at once: the mechanism is plausible and the…
What I would want from a home test that does not exist yet — what changed since Replied, post #69 · Analytics › Home & field testing · 26 Jun 2026 · 0 likes Post #68 is the version of this I will quote in future. One addition. A home refractometer is not measuring what people hope it is measuring in these preparations, and…
0.3 mL versus 0.5 mL versus 1 mL barrels: resolution matters Replied, post #83 · Devices › Syringes & needles · 24 Jun 2026 · 13 likes Post #81 describes the usual case. This is about the unusual one. U-100 means the barrel is graduated for a solution containing one hundred units of insulin per…
Coming back to: Payment method and the leverage it gives you, ranked Replied, post #8 · Sourcing › Payments · 21 Jun 2026 · 4 likes This follows post #7 rather than contradicting it. Practical note on Payment method: write down what you expect before you look. The number of times I have found what I…
Stepping down deliberately, and how to do it without losing progress — what changed since Replied, post #9 · Practice › Dosing & titration · 21 Jun 2026 · 9 likes Going back down a step is not a failure and the trials allowed it. Several protocols permitted a return to the previous dose for tolerability and then a second attempt…
A structured critique template this community uses — a second dataset Replied, post #13 · Evidence › Study critique · 18 Jun 2026 · 14 likes On post #11 — agreed on the reasoning, with one qualification. Where a critique changes your position, saying so in the thread is worth more than being right, and it is…
Dizziness on standing: the ordinary explanation first — one year on Replied, post #10 · Nutrition & Training › Hydration & electrolytes · 16 Jun 2026 · 1 like Two claims get bundled together under Dizziness on standing and they need separating. The descriptive one — this is what was observed — is usually well supported. The…
Injecting into an area that has become firm: why not to Replied, post #85 · Practice › Administration · 16 Jun 2026 · 5 likes Post #83 put the caveat in the right place and I want to underline it. If you have to inject at a different time of day than usual, that is a much smaller perturbation…
Revisiting: Mobile reading experience on long topics Replied, post #10 · Meta › Site feedback · 16 Jun 2026 · 13 likes Reporting a real defect: on a long topic the jump-to-post link scrolls to the right post but the highlight does not fire on the first load. Second load is fine.…
Comparing prices across jurisdictions without misleading yourself Replied, post #77 · Access › Pricing · 13 Jun 2026 · 5 likes This follows post #74 rather than contradicting it. One caution on comparing prices across jurisdictions: everything above assumes the underlying documentation is what…
What consumer-accessible tests can and cannot determine — a second dataset Replied, post #2 · Analytics › Home & field testing · 13 Jun 2026 · 2 likes The opening post answers the question as asked. The question underneath it is different. Trying to state the consumer-accessible tests position in a way that someone…
A certificate whose chromatogram axes do not match its stated method — one year on Replied, post #40 · Sourcing › Red flags · 4 Jun 2026 · 0 likes Worth separating two things that post #38 runs together. Documentation quality as a signal: a supplier that reports method identifiers, distinguishes specification from…
A reconstituted vial's beyond-use date and the reasoning behind common figures Replied, post #42 · Practice › Storage & stability · 4 Jun 2026 · 0 likes Same experience here, different supplier, so it is at least not unique to one of them.
A single out-of-range value on an otherwise normal panel Replied, post #54 · Clinical › Bloodwork · 2 Jun 2026 · 8 likes Nobody has said the unglamorous part of single out-of-range value yet, so: most of the variation is explained by things that are boring to write about and easy to check.
Tesamorelin has an approved indication — what that changes about the evidence Replied, post #12 · Compounds › Secretagogues & GH axis · 2 Jun 2026 · 22 likes I had written a reply contradicting post #11 and deleted it. Here is what survived. A mass result for a short peptide is more discriminating than for a long one,…
Comparing prices across jurisdictions without misleading yourself Replied, post #28 · Access › Pricing · 2 Jun 2026 · 3 likes Post #27 answers the question as asked. The question underneath it is different. The reason comparing prices across jurisdictions is hard to answer is that the obvious…
Secretagogues and glucose tolerance: the mechanistic concern Replied, post #9 · Compounds › Secretagogues & GH axis · 21 May 2026 · 5 likes Hexarelin and the earlier peptidyl secretagogues have more published human data than the newer ones and a less favourable profile, which is worth knowing before…
Designing a personal experiment that could change your mind — one year on Replied, post #45 · Research Methods › N-of-1 designs · 12 May 2026 · 1 like Coming back to post #41, because the follow-up matters more than the original answer. Nothing in a personal experiment is medical advice to anyone including yourself,…
Why the cheapest option is often not the cheapest Started this topic · Access › Pricing · 9 May 2026 · 0 likes Why the cheapest option is often not the cheapest I have a specific reason for asking rather than idle curiosity, and the context is below. Cheapest option: setting out…
Journal club: LEADER as the historical anchor Replied, post #71 · Evidence › Journal club · 8 May 2026 · 0 likes Taking post #69 at face value and following it one step further. The figures usually contain the finding and the text usually contains the interpretation. Separating…
Request: show the solution author in the topic list — what changed since Replied, post #21 · Meta › Feature requests · 1 May 2026 · 1 like Where I part company with post #19, and it is a narrow parting. Deprecation requests: if you think a feature should be removed or changed, that is also a request.…
Citation sweep results: how many references did not say what was claimed Replied, post #82 · Meta › Wiki maintenance · 22 Apr 2026 · 10 likes Worth separating two things that post #80 runs together. Question for the editors: what is the standard for adding a citation to a claim that is community practice…
Converting between mg/mL and units per dose, both directions — the long version Replied, post #39 · Practice › Reconstitution · 20 Apr 2026 · 0 likes Narrowing post #36, because the general version has more than one answer. The decimal-point error: computing 5 mg / 2 mL as 0.25 mg/mL instead of 2.5 mg/mL is the most…
When your prescriber and the evidence disagree Replied, post #9 · Clinical › Prescriber conversations · 11 Apr 2026 · 13 likes Reframing prescriber slightly, because I think the disagreement is about the question rather than the answer. If the question is "does it happen", yes. If it is "how…
Bug report: the reconstitution calculator and a rounding edge case Replied, post #69 · Data & Tools › Calculators · 10 Apr 2026 · 0 likes Noted, and I have changed what I was going to do on the strength of it.
Spike-and-recover accuracy for a peptide assay Replied, post #55 · Analytics › Method validation · 8 Apr 2026 · 23 likes Where I part company with post #54, and it is a narrow parting. What I want from this spike-and-recover accuracy thread is the list of things that would need to be true…
Blind submission and why it changes minds — the long version Replied, post #13 · Sourcing › Independent verification · 7 Apr 2026 · 0 likes Where I part company with post #9, and it is a narrow parting. It does not extend to lots nobody has seen, it is not a recommendation, and it says nothing about…
Air bubbles in a subcutaneous injection: the honest risk assessment — does this still… Replied, post #30 · Practice › Administration · 28 Mar 2026 · 0 likes Bleeding at the site is common and unremarkable at these needle gauges. Persistent bruising in the same area repeatedly is worth a change of technique or of site rather…
Liver enzymes drifting down and what that usually means Replied, post #71 · Clinical › Bloodwork · 27 Mar 2026 · 15 likes Liver enzyme changes during rapid weight loss are commonly reported and have several possible explanations, which is exactly why they need clinical interpretation…
Packaging that arrived damaged: documenting it properly — a second dataset Replied, post #59 · Sourcing › Logistics · 20 Mar 2026 · 0 likes Import restrictions by jurisdiction: what is legal to import for personal use varies enormously by country. Some jurisdictions are quite permissive; others are not.…
Coming back to: A community side-effect dataset, with its response rate and biases Replied, post #38 · Data & Tools › Datasets · 15 Mar 2026 · 1 like Summarising the community side-effect dataset thread so far, since it is long and the answer is buried: the first reply has the method, the fourth has the correction to…
Revisiting: Journal club: SURMOUNT-1, read without the press release Replied, post #24 · Evidence › Journal club · 9 Mar 2026 · 0 likes Everything in post #23 holds. The case it does not cover is the one I have. Reading order that works for these sessions: registry entry, methods, baseline table,…
What a good consultation looks like from the other side Replied, post #22 · Clinical › Prescriber conversations · 8 Mar 2026 · 10 likes Good consultation has a well-known answer and a correct answer, and the interesting work is establishing that they are the same. Nobody has done that here yet.
[2026 update] Amylin and gastric emptying: overlapping mechanisms with incretins Replied, post #22 · Compounds › Cagrilintide & amylin analogues · 3 Mar 2026 · 0 likes Amylin and gastric emptying has a well-known answer and a correct answer, and the interesting work is establishing that they are the same. Nobody has done that here yet.
An ABAB design with a data table and honest limitations — a second dataset Replied, post #10 · Research Methods › N-of-1 designs · 23 Feb 2026 · 0 likes Statistical analysis of n-of-1 data: comparing before versus after with a t-test or similar is one approach. Plotting the data visually is another. Both are valid.
Revisiting: A page that has drifted out of date and needs a maintainer Replied, post #102 · Documentation › Wiki requests · 22 Feb 2026 · 27 likes Documents that are mostly a worked example age better than documents that are mostly a summary, because the arithmetic does not change. The uncertainty is in the…
Mass error in ppm: the arithmetic and the caveat Replied, post #122 · Analytics › Mass spectrometry · 16 Feb 2026 · 0 likes I have three months of notes on mass error in ppm and the honest summary is that the trend is real and the week-to-week numbers are noise. I nearly drew the opposite…
Coming back to: Training through a dose escalation week Replied, post #22 · Nutrition & Training › Resistance training · 4 Feb 2026 · 5 likes Coming back to post #18, because the follow-up matters more than the original answer. Frequency matters less than consistency and progression. Two sessions a week done…
Second pass at: Choosing a concentration on purpose rather than by accident Replied, post #5 · Practice › Reconstitution · 4 Feb 2026 · 4 likes Worked example, since the arithmetic is the whole question. Five milligrams into one millilitre is 5 mg/mL. A 0.25 mg dose is 0.05 mL, which is five units on a U-100…
Coming back to: Reading a supplier's product description as a marketing document Replied, post #10 · Compounds › Other compounds · 30 Jan 2026 · 12 likes Nicotinamide adenine dinucleotide preparations are not peptides at all and the certificate conventions are completely different. Reading one as though it were a peptide…
Reading U-100 graduations, with a conversion table Replied, post #9 · Devices › Syringes & needles · 29 Jan 2026 · 0 likes Agreed on reading U-100 graduations, with one qualification that I think matters. The reasoning holds for the case as described. Change the starting assumption and it…
How to ask about something you suspect is a bad idea Replied, post #46 · Start Here › How to Ask · 20 Jan 2026 · 22 likes Building on post #44 rather than restating it. Arithmetic questions: write out the steps. "I have a 10 mg vial, I added 2 mL, I want a 0.25 mg dose, and I get this…
Research-use-only labelling: what it means and what it does not Replied, post #70 · Sourcing › Regulatory · 9 Dec 2025 · 27 likes Worth separating two things that post #68 runs together. Research-use-only status is a legal classification, not a safety classification. It means the compound is sold…
A history of disordered eating: proceeding carefully Replied, post #23 · Wellbeing › Mental health · 8 Dec 2025 · 0 likes Eating-disorder history is raised here regularly and is the case where guidance most consistently recommends specialist involvement. The general answer and the answer…
Robustness: the parameters worth deliberately varying Replied, post #43 · Analytics › Method validation · 5 Dec 2025 · 4 likes Robustness was covered in the wiki last year and the page has a review date on it, which is a better starting point than my memory of a thread.
Interpreting a result that disagrees with the supplier's certificate Replied, post #29 · Sourcing › Independent verification · 1 Dec 2025 · 28 likes Everything in post #25 holds. The case it does not cover is the one I have. Checked the interpreting a result claim against the primary source this morning. It…
Follow-up: Glucagon receptor agonism in a weight-loss compound Replied, post #8 · Pharmacology › Receptor biology · 22 Nov 2025 · 23 likes Biased agonism — where different ligands at the same receptor favour different downstream pathways — is a plausible explanation for differences between compounds in…
Liver enzymes drifting down and what that usually means Replied, post #26 · Clinical › Bloodwork · 10 Nov 2025 · 21 likes A single value outside interval: usually uninformative on a single draw. What makes a result interesting: a trend across multiple draws, a magnitude well beyond the…
Coming back to: Why quantitation is the hard part, not detection Replied, post #86 · Analytics › Home & field testing · 29 Oct 2025 · 2 likes What I would tell a new member reading about quantitation for the first time: the confident posts are not the reliable ones, and the reliable ones are longer.
Documentation that materially improves an appeal's chances Replied, post #41 · Access › Insurance & coverage · 26 Oct 2025 · 12 likes Documentation is one of those subjects where the general answer and the answer for a specific case diverge, and the thread will go in circles until someone says which…
Detection wavelength and why 214 nm and 280 nm disagree Replied, post #69 · Analytics › HPLC & UHPLC · 23 Oct 2025 · 0 likes Taking post #67 at face value and following it one step further. Reading back through the detection wavelength threads from last year, the same three questions come up…
The most useful thing you learned here that was not the answer you came for — a second… Replied, post #110 · Lounge › Off topic · 20 Oct 2025 · 4 likes Newer drugs and mechanisms: when a new drug launches or a new mechanism is discovered, the Lounge is a place to discuss the news and speculate before hard data exists.…
Compounds this community declines to help with, and why Replied, post #31 · Compounds › Other compounds · 29 Sep 2025 · 2 likes Thymosin alpha-1 has a regulatory history in several jurisdictions and a real clinical literature, which puts it in a different evidential category from most of its…
Trial registration and comparing the protocol with the paper Replied, post #42 · Evidence › Trials · 28 Sep 2025 · 0 likes Adding a note of thanks rather than an opinion. I did not know most of that.
Citing a preprint in a maintained document: our rule and its reasoning — does this still… Replied, post #33 · Evidence › Preprints · 28 Sep 2025 · 27 likes Post #30 is the version of this I will quote in future. One addition. Where a preprint's numbers are the basis of a claim being repeated here, someone should check…
Second pass at: Journal club: STEP 4 and what a withdrawal design can prove Replied, post #70 · Evidence › Journal club · 25 Sep 2025 · 4 likes The most common failure mode is spending fifty minutes on the effect size and ten on the population. Reversing that ratio would improve most sessions.
Reverse causation in a cohort study of weight and outcome — a second dataset Replied, post #26 · Evidence › Study critique · 13 Sep 2025 · 32 likes Picking up post #23: that is the part I would want checked first. An honest declaration on Reverse causation: I have a prior here and it is strong enough that you…
Angle of injection and whether 90 degrees is always right Replied, post #21 · Practice › Administration · 11 Sep 2025 · 0 likes Post #20 answers the question as asked. The question underneath it is different. Air bubbles in a subcutaneous injection: the honest risk assessment is low. Tiny air…
[2026 update] Does dual agonism explain the effect size, or is it dose? Replied, post #16 · Compounds › Tirzepatide · 9 Sep 2025 · 14 likes Before the thread moves on from dual agonism — what is the sample size behind the claim? I am not being difficult; I have seen the same figure quoted from an n of four…
Second pass at: The mass-error checker and its intended scope Replied, post #14 · Data & Tools › Calculators · 9 Sep 2025 · 7 likes Post #13 answers the question as asked. The question underneath it is different. The most common input error is entering the vial mass in the concentration field. It…
Fatigue in the first month: how much is the drug and how much is intake — what changed… Replied, post #70 · Practice › Side effects · 3 Sep 2025 · 25 likes Building on post #69 rather than restating it. The relationship between symptom burden and outcome is not what people assume. Feeling worse is not evidence of a larger…
A ten-fold dose error caught before injection — one year on Replied, post #84 · Devices › Syringes & needles · 3 Aug 2025 · 2 likes That matches what I have seen, for whatever a single anecdote is worth.
A field-by-field walk through a certificate of analysis Replied, post #21 · Analytics › COA interpretation · 14 Jul 2025 · 0 likes Field-by-field walk through a certificate is a question about a distribution, not about a value, and treating it as a value is what produces the confident wrong answers.
Revisiting: Reading a denial letter as a specification for your appeal Replied, post #44 · Access › Insurance & coverage · 14 Jul 2025 · 30 likes Reading this Reading a denial letter thread as someone who came in with a fixed view: the third and seventh replies moved me and the confident ones did not.
[2026 update] US compounding rules and how they changed Replied, post #24 · Regional › North America · 11 Jul 2025 · 0 likes Adding the measurement that post #21 says would settle it. Cross-border purchasing raises both a legal question and a practical one, and the legal one is yours to…
Revisiting: Reading a denial letter as a specification for your appeal Replied, post #39 · Access › Insurance & coverage · 9 Jul 2025 · 27 likes The stated reason for a denial is the generalisable part of anybody's account here. The outcome is not.
What a documentation review can and cannot tell you Replied, post #25 · Sourcing › Independent verification · 5 Jul 2025 · 0 likes On documentation review, I would rather understate and be corrected upward than overstate and be quoted. That is a house style here and it is a good one.
Reverting an edit that had no revision note Replied, post #14 · Meta › Wiki maintenance · 1 Jul 2025 · 21 likes Agreed. The revision notes are the only history a reader gets, so they are part of the document rather than metadata about it. That is the honest state of it as of this…
Interim analyses and stopping rules — does this still hold? Replied, post #15 · Evidence › Trials · 28 Jun 2025 · 30 likes Second this, and I would have said it less carefully.
Follow-up: The lowest dose that does anything: is that a real question? Replied, post #23 · Practice › Dosing & titration · 19 Jun 2025 · 17 likes If you are stepping up mainly because the schedule says so rather than because the current dose has stopped doing what you wanted, that is worth noticing before rather…
Whether an aggregate is worth publishing at all: a disputed topic Replied, post #6 · Data & Tools › Datasets · 17 Jun 2025 · 8 likes Worth separating two things that post #4 runs together. The useful distinction on whether an aggregate is between what was measured and what was inferred from it. Both…
[2026 update] An appeal that failed, and what I would do differently Replied, post #156 · Access › Insurance & coverage · 17 Jun 2025 · 8 likes Keep every document with dates in one place. An appeal months later is assembled from whatever you kept.
Titles that describe the question, not the situation Replied, post #29 · Start Here › How to Ask · 16 Jun 2025 · 8 likes I read post #27 twice before replying, because I had assumed the opposite. Chromatogram questions: describe the method first. Column type, gradient, wavelength,…
Insulin combinations and hypoglycaemia risk Replied, post #9 · Practice › Interactions · 15 Jun 2025 · 0 likes A supplement is a drug for interaction purposes, and the fact that it is sold without a prescription tells you nothing about whether it interacts. The paperwork is…
Coming back to: Getting a referral rather than a refusal Replied, post #64 · Clinical › Prescriber conversations · 13 Jun 2025 · 0 likes Answering the question post #60 raises rather than the one it answers. A second opinion is a normal part of medicine rather than an accusation, and asking how to obtain…
Follow-up: Tracking intake honestly when appetite is absent Replied, post #54 · Nutrition & Training › Protein & intake · 10 Jun 2025 · 4 likes Where the Tracking intake reasoning breaks down for me is the step from the group result to the individual case. That step is almost never argued for.
Coming back to: What published stability data actually covers, and what it does not Replied, post #59 · Practice › Storage & stability · 9 Jun 2025 · 6 likes Adding the measurement that post #56 says would settle it. A note on how published stability data actually covers gets discussed rather than on published stability data…
Coming back to: Why the cheapest option is often not the cheapest Replied, post #23 · Access › Pricing · 8 Jun 2025 · 19 likes This follows post #22 rather than contradicting it. Cost per week at a maintenance dose is the figure most people actually want and least often calculate.
Follow-up: Tracking intake honestly when appetite is absent Replied, post #18 · Nutrition & Training › Protein & intake · 4 Jun 2025 · 2 likes The documentation on Tracking intake is better than this thread and I say that as someone who has posted in the thread.
Splitting a vial for two laboratories: how to do it without ruining both Replied, post #51 · Sourcing › Independent verification · 31 May 2025 · 0 likes A record with four results over sixteen months is a thin record rather than a bad one, and the honest description says which.
Comparing my trajectory with the trial curves, carefully Replied, post #8 · Outcomes › Progress reports · 26 May 2025 · 0 likes Where I part company with post #6, and it is a narrow parting. Self-reported intake is optimistic in a consistent direction, and saying so in your own report is more…
[2026 update] US compounding rules and how they changed Replied, post #15 · Regional › North America · 25 May 2025 · 20 likes Cost comparisons should state whether they include the device and the dispensing fee, because those differ between routes and between states.
Follow-up: Requesting a page: what makes a good request Replied, post #32 · Documentation › Wiki requests · 9 May 2025 · 8 likes Name a willing maintainer in the request. Point three of the criteria stops more nominations than the other three combined. Adding this to the thread rather than to the…

Obstructive sleep apnoea and a hard endpoint in this class Replied, post #62 · Clinical › Comorbidities · 19 Apr 2025 · 0 likes This is the answer, and the reason it is the answer is the more useful part.
Retatrutide dose escalation in the published trials Replied, post #124 · Compounds › Retatrutide · 13 Apr 2025 · 30 likes Mass and identity: a report on retatrutide should state the mass detected by LC-MS, not assume a theoretical mass. The theoretical mass is not published in…
Hepatic steatosis: what the MASH trial evidence supports Replied, post #16 · Clinical › Comorbidities · 10 Apr 2025 · 19 likes The most useful reply I ever got about hepatic steatosis was a request to state my units. It sounds like pedantry and it has saved me twice.
