Speaking as somebody who asked badly last month and got a polite request for four missing details: writing the question properly the first time takes ten minutes and saves two days. Learn from me.
How much context is too much context in a first post? I have a specific reason for asking rather than idle curiosity, and the context is below.
Counting it rather than describing it, because the count is the part that can be argued with.
9 instances over 9 weeks, recorded the same way each time, 3 of them different enough from the rest that I have set them aside and said so.
That is the whole dataset. The question in the title is what it does and does not support.
Questions you cannot explain: "I cannot say why I am asking this, but is this compound stable at room temperature?" is more productive than no question at all. People here know that some questions cannot be asked in public and they will work with that constraint.
Staff note on titles, since it comes up. We retitle topics fairly often, always leaving the original in the first post and always logging it. It is not a criticism of the wording — it is that a title is how somebody finds this in eighteen months.
Worth separating two things that the opening post runs together.
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 number for the syringe mark" is answerable. "How many units" is not.
I have kept the units in throughout, for the obvious reason.
Post #5 is right about the mechanism and I think understates the practical bit.
Avoid "any advice?" at the end. It is so generic that people do not know which part of the post it refers to. Pick the specific part and ask that specific question instead.
Not the answer, but possibly the question that gets there.
Lab result questions: state the result, the reference interval, and what else is on the same panel. A single flag on a single draw is usually uninformative without context.
It is one reading of the data and not the only reasonable one.
Context that matters: compound, how long in, current dose, relevant history. Context that does not matter: how you feel, your hopes for the outcome, your medical history beyond what affects this specific question. The first set gets you answered. The second set makes the reply longer without making it better.
That is a description of practice, not a recommendation of it.

When you quote a figure from somewhere else, say where from. Not as a formality — the answer frequently depends on whether the number came from a certificate, an independent report or a forum post.
What you have already read matters. Saying "I read the maintained page on this and I still have a gap" tells people they do not need to point you at the same resource you have already found. That is a genuine time saver.
The specific question in the title is more useful than you might think. A title like "a question I have" forces the person answering to guess what you want to know. A title with the actual question gets you an answer in two hours instead of two days.
This follows post #10 rather than contradicting it.
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 least and ask that one first.
That is one dataset and I would not build a rule on it.
Post #13 answers the question as asked. The question underneath it is different.
Chromatogram questions: describe the method first. Column type, gradient, wavelength, detection method. Everything else follows from method. A chromatogram without method is a number without context.
Marking that as an opinion rather than a finding.
That is clearer than the version I had in my head. Thank you.
Coming back to post #16, because the follow-up matters more than the original answer.
A question about somebody else's post should be a reply to that post, not a new topic. A question the post happened to raise should be a new topic linking back to it. The difference is whether the answer is useful without the original.
I would put the burden of proof on the interesting explanation, not the dull one.
It is fine to say you cannot explain why you are asking. Nobody will press, and the technical part of the question can usually be answered without the context.
I checked the source rather than the summary, and they differ.
Understood. Thank you for being specific about the limits of it.
On post #18 — agreed on the reasoning, with one qualification.
Chromatography questions need the method before anything else: column, gradient, wavelength, injection volume. A purity figure with no method attached cannot be discussed, only repeated.
That is the practical version. The rigorous version is longer and says the same thing.
Post #21 answers the question as asked. The question underneath it is different.
Edit the first post rather than adding the missing detail in reply nine. People arriving later read the first post and stop.
Happy to be corrected if someone holds better data than mine.
Post the arithmetic you already did. Half the questions here are answered by someone spotting which line of your working is wrong, and that is impossible if you only give the answer you got.
A guess, clearly labelled as one.
Noted, and thank you for writing it out rather than summarising it.
Quantities without units are the single commonest reason a question sits unanswered. "Two and a half" is not a dose, a volume or a concentration until you say which.
Disagreement-style questions: "I read this and it contradicts what I heard here, which is right?" is answerable. "Is this a bad idea?" without giving the context is not.
Do not apologise in the first line. It costs you the space where the question should be, and nobody here thinks a question is an imposition.
Seconded. It reads as careful rather than confident, which is the right register.
