Questions with no answer at all. Not questions with no accepted answer — those are elsewhere.
Numbers first: an HPLC purity test · orforglipron. I would rather over-plan the first cycle and simplify later. I am prepared to do the work if someone can tell me…
I have both a purity figure and a content figure, which is why the discrepancy is visible. I would rather over-plan the first cycle and simplify later. I am prepared…
The clinician who ordered the panel was not concerned; I would still like to understand it. The figures are clear enough; the question is what they mean and what they…
Conditions: 96.4% · a C4 column · dulaglutide. The figures are clear enough; the question is what they mean and what they do not. I can supply the numbers if the…
The specifics, since they change the answer: liraglutide · 10 mg/mL. I am at the decision point and I would rather think it through than improvise. I would rather…
I have read the medicinal chemistry paper and the pharmacology paper, which helped and did not finish the job. I am trying to choose between two options that are…
Concretely: Suzhou · Norway. I would like to know the limits of what can be inferred from this. What I am trying to avoid is over-reading a single result, which I…
The case in front of me: nausea · oral semaglutide · PIONEER-1. I would like to know the limits of what can be inferred from this. What I am trying to avoid is…
For reference: date of analysis · QST. I would like to define my thresholds before I have a result, for obvious reasons. I want a plan with explicit stopping rules,…
What I am working with: 5 mg · 8 mg/mL. I have worked this out and I would like someone to find the error, because I suspect there is one. My working so far, for the…
Concretely: early satiety · liraglutide · STEP 1. I would like to know the limits of what can be inferred from this. What I am trying to avoid is over-reading a…
For reference: MKM · semaglutide. Somebody stated this to me confidently and I would like to check it before repeating it. I would accept a well-reasoned negative…
Stated plainly: 5 mg · two weeks · early satiety. I keep seeing this stated as a fact with no explanation attached, and unexplained facts make me suspicious. My…
The case in front of me: magnesium · tirzepatide. I want to decide this in advance so that I am not deciding it under pressure later. Assume I will follow the plan I…
The case in front of me: a Karl Fischer water content test · liraglutide. I want to decide this in advance so that I am not deciding it under pressure later. Assume I…
Stated plainly: Suzhou · the United States. I have read the primary source rather than the summary, which has left me with more questions. I understand the headline.…
For reference: tirzepatide · forty-two days. I would rather understand the derivation than memorise the outcome. Two people I asked gave two answers that differ by a…
The particulars: liraglutide · 99.1%. I would rather understand the derivation than memorise the outcome. Two people I asked gave two answers that differ by a factor…
I am comparing a supplier certificate against an independent result on the same lot. I have worked this out and I would like someone to find the error, because I…
Stated plainly: STEP 3 · mazdutide. This is asserted often enough that I assumed it was established, and then I went looking for the source. I have searched the…
Setup, so nobody has to ask: orforglipron · 2 mg/mL. I would like to set this up properly once, rather than adjust it repeatedly. My budget is real but not tight, and…
Stated plainly: 95.2% · a C18 column · semaglutide. I have read the primary source rather than the summary, which has left me with more questions. I understand the…
What I have: vomiting · orforglipron. I can predict the outcome but I cannot explain it, which means I will get the next case wrong. I would like to know how…
For reference: a 1 mL luer-lock syringe · 60 mg · 3.33 mg/mL. I would rather understand the derivation than memorise the outcome. Two people I asked gave two answers…
