The case in front of me: semaglutide · 5 mg/mL. I have done this once and I suspect I got away with it rather than got it right. For context: I keep records of every…
For reference: tirzepatide · 2–8 °C. I have read the obvious sources and they disagree with each other, so I would rather ask people who have actually done this. I…
Every supplier sheet I have says "store lyophilised powder at −20 °C for long-term, 2–8 °C for short-term, room temperature acceptable for shipping". Nobody explains…
Conditions: semaglutide · 30 °C. I have done this once and I suspect I got away with it rather than got it right. For context: I keep records of every batch, every…
Stated plainly: aggregation · a GLP-1 receptor agonist · minus 80 °C. I keep seeing this stated as a fact with no explanation attached, and unexplained facts make me…
Conditions: oxidation · minus 20 °C. This is one of those things that everyone repeats and nobody derives. This matters practically, not just academically, because it…
What I am working with: dulaglutide · 25 °C. This is a procedural question rather than a theoretical one, and I would like the procedure rather than the theory. What…
Stated plainly: orforglipron · 5 mg/mL. This is a procedural question rather than a theoretical one, and I would like the procedure rather than the theory. What I…
What I have: mazdutide · 30 °C. I would rather be corrected now than propagate something wrong. I am specifically not interested in a testimonial; I am interested in…
Stated plainly: dulaglutide · room temperature. This has the shape of a fact but I cannot find its origin. What I found instead were three secondary sources all…
The case in front of me: oxidation · liraglutide · Janoshik. I have done this once and I suspect I got away with it rather than got it right. For context: I keep…
The particulars: fibrillation · ecnoglutide · 2–8 °C. I understand the observation; what I do not understand is the mechanism behind it. I have read the two review…
Concretely: semaglutide · 37 °C · five days. I want to decide this in advance so that I am not deciding it under pressure later. Assume I will follow the plan I write…
Details up front: hydrolysis · retatrutide · 4 °C. I suspect the usual explanation for this is wrong, or at least incomplete. I am aware this may have a boring…
The vial was lyophilised at the time, which I understand may matter a great deal. I keep seeing this stated as a fact with no explanation attached, and unexplained…
Numbers first: mazdutide · 30 °C. I would like to understand the steps well enough to explain them to someone else. I have access to a refrigerator with a logger and…
The specifics, since they change the answer: 25 °C · ecnoglutide. Somebody stated this to me confidently and I would like to check it before repeating it. I would…
Setup, so nobody has to ask: aggregation · mazdutide · 30 °C. The empirical answer seems settled. The explanation does not. If the honest answer is that nobody knows,…
Setup, so nobody has to ask: 25 °C · cagrilintide. This has the shape of a fact but I cannot find its origin. What I found instead were three secondary sources all…
Numbers first: hydrolysis · dulaglutide · 37 °C. I suspect the usual explanation for this is wrong, or at least incomplete. I am aware this may have a boring answer.…
