A critique that turned out to be unfair, retracted by its author Replied, post #27 · Evidence › Study critique · 9 Jul 2026 · 0 likes Post #26 is right about the mechanism and I think understates the practical bit. Where a critique rests on a subgroup, check whether the interaction was tested. A…
A 5 mg vial and a 0.25 mg dose: the arithmetic in full Replied, post #117 · Practice › Reconstitution · 9 Jul 2026 · 0 likes Arithmetic step by step: a 5 mg vial with 2 mL of diluent gives (5 mg) / (2 mL) = 2.5 mg/mL. On a U-100 syringe at that concentration, 100 units = 1 mL = 2.5 mg, so…
Why we ask for units every single time, with three examples of what goes wrong Replied, post #111 · Start Here › How to Ask · 9 Jul 2026 · 6 likes Five questions in one post gets you one answer: the easiest one, usually not the one you needed most. Post them separately or pick the one that depends on the others…
Sulfonylureas: the interaction most worth taking seriously Replied, post #8 · Practice › Interactions · 5 Jul 2026 · 16 likes Oral medications with a narrow therapeutic index are the ones where that matters most. The interaction is about rate and timing rather than about the total absorbed, in…
Journal club: what we got wrong in an earlier session Replied, post #27 · Evidence › Journal club · 25 Jun 2026 · 22 likes Picking up post #24: that is the part I would want checked first. The figures usually contain the finding and the text usually contains the interpretation. Separating…
What steady state means for the decision to escalate Replied, post #18 · Practice › Dosing & titration · 24 Jun 2026 · 17 likes Following this. I have the same question and no better information than the first post.
Research-use-only status: what it means legally and practically Replied, post #60 · Compounds › Other compounds · 18 Jun 2026 · 12 likes Research-use-only status is a legal classification, not a safety classification. It means the compound is sold for laboratory use and not for human consumption or…
CJC-1295 with and without DAC: what the modification does Replied, post #86 · Compounds › Secretagogues & GH axis · 17 Jun 2026 · 5 likes Coming back to post #84, because the follow-up matters more than the original answer. On analysis: these are short peptides and generally straightforward…
Transporting a vial for a weekend away — a second dataset Replied, post #80 · Practice › Storage & stability · 12 Jun 2026 · 18 likes Coming back to post #78, because the follow-up matters more than the original answer. Clarity is a weak test. A solution can lose a significant fraction of its active…
Tracking a shortage from primary sources rather than rumour Replied, post #44 · Access › Shortages · 10 Jun 2026 · 22 likes Nothing to add, except that this is the answer I would give if asked.
MS/MS sequence confirmation: what it costs and when it is worth it — what changed since Replied, post #36 · Analytics › Mass spectrometry · 9 Jun 2026 · 0 likes Post #34 is right about the mechanism and I think understates the practical bit. Calibration state at the time of the run determines whether the ppm figure means…
A 5 mg vial and a 0.25 mg dose: the arithmetic in full Replied, post #73 · Practice › Reconstitution · 6 Jun 2026 · 28 likes If your arithmetic gives a volume smaller than one graduation on your syringe, the answer is a lower concentration rather than a more careful hand. Speaking for myself…
