A 5 mg vial and a 0.25 mg dose: the arithmetic in full Replied, post #110 · Practice › Reconstitution · 4 Jul 2026 · 5 likes A 10 mg vial reconstituted three different ways: 1 mL diluent gives 10 mg/mL, 2 mL gives 5 mg/mL, 4 mL gives roughly 2.5 mg/mL. The arithmetic is the same; the…
Reading order for a first week here, and what to skip until later — what changed since Replied, post #6 · Start Here › Welcome · 2 Jul 2026 · 16 likes Adding the boring version of Reading order, because the interesting version keeps getting posted and the boring one is usually right. Check the ordinary explanations,…
What a reversed-phase purity number actually is Replied, post #3 · Analytics › HPLC & UHPLC · 25 Jun 2026 · 0 likes Mobile-phase preparation is a genuine source of between-laboratory variation. Acid concentration and organic modifier both shift retention, and neither is usually…
A critique that turned out to be unfair, retracted by its author Replied, post #18 · Evidence › Study critique · 24 Jun 2026 · 23 likes Building on post #17 rather than restating it.

Fasting versus non-fasting and which tests care Replied, post #46 · Clinical › Bloodwork · 11 Jun 2026 · 2 likes Post #43 is the version of this I will quote in future. One addition. Glycaemic markers integrate over different periods. A point glucose and a longer-term marker…
Micronutrient adequacy at low total intake Replied, post #45 · Nutrition & Training › Protein & intake · 10 Jun 2026 · 0 likes Liquid sources are tolerated better than solid ones by many people here, and that is a practical observation rather than a nutritional principle. Happy to be the one…

Second pass at: Programming during a large energy deficit Replied, post #8 · Nutrition & Training › Resistance training · 31 May 2026 · 4 likes A note on how Programming during a large energy gets discussed rather than on Programming during a large energy itself: the confident posts get the replies and the…
Coming back to: Time to steady state after a dose increase Replied, post #61 · Pharmacology › Pharmacokinetics · 25 May 2026 · 1 like Metabolism for peptide drugs is proteolytic rather than hepatic in the usual sense, which is why the cytochrome interaction questions that dominate small-molecule…
Fasting versus non-fasting and which tests care Replied, post #33 · Clinical › Bloodwork · 22 May 2026 · 0 likes Fasting state, time of day, recent exercise and hydration all move several common analytes. Standardising the conditions matters more than the interval between draws.
Second pass at: The storage lookup and where its data comes from Replied, post #14 · Data & Tools › Calculators · 7 May 2026 · 22 likes Confirming post #11 from a second method, which matters more than confirming it from a second person. On storage lookup: the maintained page in the documentation…
Washout with a one-week half-life: the arithmetic — does this still hold? Replied, post #13 · Research Methods › N-of-1 designs · 5 May 2026 · 16 likes The question underneath Washout is usually "how would I tell?" rather than "what is true?", and that one has a method attached to it.

Journal club: is percentage weight change the right endpoint? Replied, post #84 · Evidence › Journal club · 19 Apr 2026 · 7 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. I would not lead…
Anaesthesia and elective surgery: the aspiration question Replied, post #88 · Practice › Interactions · 16 Apr 2026 · 15 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…
List price versus negotiated price versus what you pay Replied, post #51 · Access › Pricing · 12 Apr 2026 · 5 likes Pharmacy acquisition cost: a pharmacy pays less than the patient pays, even at insurance rates. That margin is where the pharmacy's costs and profit live. One more…

[2026 update] Does a peptide degrade silently, with no visual change? Replied, post #41 · Practice › Storage & stability · 1 Apr 2026 · 11 likes Confirming post #40 from a second method, which matters more than confirming it from a second person. Visible particulate is a strong signal in the other direction: it…
Follow-up: An emergency department visit, described afterwards Replied, post #2 · Safety › Adverse events · 30 Mar 2026 · 11 likes Coming back to the opening post, because the follow-up matters more than the original answer. Gallbladder symptoms during rapid weight loss are described in this class…

How to ask about something you suspect is a bad idea Replied, post #59 · Start Here › How to Ask · 26 Feb 2026 · 1 like A photograph of a vial is rarely useful and a photograph of a document usually is. Redact the identifiers before you post either. The strength of my opinion here…

Detection wavelength and why 214 nm and 280 nm disagree Replied, post #11 · Analytics › HPLC & UHPLC · 25 Jun 2025 · 6 likes One caution on detection wavelength: everything above assumes the underlying documentation is what it claims to be. That assumption is doing real work and is rarely…

[2026 update] An appeal that failed, and what I would do differently Replied, post #111 · Access › Insurance & coverage · 14 Jun 2025 · 1 like Filing a mild objection to the consensus on appeal. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit.
Follow-up: Tracking intake honestly when appetite is absent Replied, post #70 · Nutrition & Training › Protein & intake · 12 Jun 2025 · 8 likes Fibre: adequate fibre intake supports fullness and gut motility, both of which matter during the gastrointestinal effects of these compounds.

Maintainer handover: how it works Replied, post #19 · Meta › Wiki maintenance · 14 Mar 2025 · 12 likes On maintainer handover, 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.
Review: a draft on reconstitution arithmetic, with objections Replied, post #54 · Documentation › Doc review · 11 Mar 2025 · 0 likes The limitations section is the part most often thin at review and most often load-bearing afterwards.

Adjudicated events and why the definition matters — the long version Replied, post #41 · Evidence › Trials · 10 Mar 2025 · 20 likes Nobody has said the unglamorous part of Adjudicated events yet, so: most of the variation is explained by things that are boring to write about and easy to check.
Biased agonism: a real phenomenon, an over-used explanation Replied, post #29 · Pharmacology › Receptor biology · 2 Mar 2025 · 20 likes The arithmetic in post #26 is right; the assumption feeding it is the part to check.
