Post #28 answers the question as asked. The question underneath it is different.
Small methodological point on pinch: repeating a measurement is cheap and resolves most of what is being argued about here at no cost to anyone.

Pinch or no pinch, and how needle length changes the answer posts 31–60
This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.
I read post #31 twice before replying, because I had assumed the opposite.
Leaving the needle in for a couple of seconds after depressing the plunger reduces leakage at the site. It costs nothing and it is the fix for the "some came back out" question.
It cost nothing to check and would have cost something not to.

f.villalobos, post #20: Pinch has a well-known answer and a correct answer, and the interesting work is establishing that they are the same. Nobody has done that here yet. Go to post
I would keep pinch and the decision it usually gets used for separate in this thread. They are related and they are not the same question, and merging them is why the last one went badly.
Pinch is worth one more sentence than it usually gets, and the sentence is the one about how the number was arrived at.

Everything in post #35 holds. The case it does not cover is the one I have.
If you have to inject at a different time of day than usual, that is a much smaller perturbation than it feels for a weekly compound with a week-long half-life.
I would want to see it done twice before believing it once.

Building on post #36 rather than restating it.
Injecting into an area that has become firm: lipohypertrophy — thickened fatty tissue from repeated injection in one area — changes local tissue absorption. Avoid injecting into areas that are noticeably firm or lumpy and allow those areas to recover for at least a few months.
A partial answer, offered because a partial answer beats none.

An honest declaration on pinch: I have a prior here and it is strong enough that you should weight what I say downward. Stating it rather than hiding it.
Injection discomfort: comes from needle gauge (finer = less discomfort), volume (smaller = less discomfort), temperature (room temperature or warmed is less uncomfortable than cold), and technique (smooth, purposeful injection is less uncomfortable than hesitant). All four are under your control.

Needle length matters less than angle for subcutaneous delivery in most people. A short needle at ninety degrees and a longer one at forty-five put the material in roughly the same place.

What I would tell a new member reading about pinch for the first time: the confident posts are not the reliable ones, and the reliable ones are longer.

On post #39 — agreed on the reasoning, with one qualification.

That is the shape of it. The detail is where I would expect to be corrected.

f.fenwick, post #13: Picking up post #10: that is the part I would want checked first. I would be cautious about generalising from the pinch example above. It is a good example. It is one example. Go to post
This follows post #43 rather than contradicting it.
An update on my earlier pinch post: the pattern held for another six weeks and then stopped, which I did not predict and cannot explain.
Drawing up with one needle and injecting with another: a reasonable practice if you have extra needles. Fresh needle for injection reduces tissue drag and can decrease discomfort. Not necessary, but not harmful either.
Stating my assumptions rather than smuggling them in.

b.jankowiak, post #29: Post #25 describes the usual case. This is about the unusual one. The reason pinch is hard to answer is that the obvious measurement and the relevant quantity are not the same thing, and substituting one for the other is silent. Go to post
On post #43 — agreed on the reasoning, with one qualification.
Adding a null result on pinch. I looked, carefully, and found nothing, and null results deserve posting precisely because they never are.

Pinch would be much easier to settle if anyone reported the denominator. Almost nobody reports the denominator.
Post #47 answers the question as asked. The question underneath it is different.
The single most common technique error described here is drawing to the wrong graduation because the barrel was read at an angle. Read it straight on, at eye level, every time.
Not the whole picture, but the part of it I can speak to.

Confirming post #50 from a second method, which matters more than confirming it from a second person.
What I would want before treating pinch as settled: the method, the sample, and whether anyone tried to find the opposite result. Two of the three are usually missing.

Grateful for the specificity. Vague answers to this question are what sent me looking.

k.kimani, post #12: Bleeding at the site is common and unremarkable at these needle gauges. Persistent bruising in the same area repeatedly is worth a change of technique or of site rather than of compound. One case, stated as one case. Go to post
Pinch is well covered in the tag pages, and the older discussions are better than the recent ones because they were argued out properly. Worth twenty minutes before adding to this one.

Pinching a fold is useful for lean tissue and unnecessary elsewhere. The point is to keep the needle out of muscle, and whether you need to depends on the site and on you.
Collapsed as off-topic by two members at trust level 3 or above
Post #54 is right about the mechanism and I think understates the practical bit.
Taking pinch seriously for a moment rather than deflecting: the honest position is that the community has observations and no controlled comparison, and those two things support very different sentences.
Bleeding at the site is common and unremarkable at these needle gauges. Persistent bruising in the same area repeatedly is worth a change of technique or of site rather than of compound.
I would rather be precise about what I do not know than vague about what I do.

Pinch or no pinch: the decision depends on needle length and on your own anatomy. A longer needle (8 mm and up) reaches subcutaneous tissue easily without a pinch. A shorter needle (4-6 mm) is safer with a gentle pinch. The pinch size matters less than people think; the injection angle matters more.

Agreed on pinch, with one qualification that I think matters. The reasoning holds for the case as described. Change the starting assumption and it does not, and the starting assumption is the part nobody states.
Bleeding at the injection site: normal and usually minimal. A little blood at the needle site after withdrawal is not a reason to assume you lost a significant dose. The needle passed through tissue and there is a small amount of bleeding in the tract.
If anyone has run this properly I would rather read that than my own guess.

Injecting into an area that has become firm: lipohypertrophy — thickened fatty tissue from repeated injection in one area — changes local tissue absorption. Avoid injecting into areas that are noticeably firm or lumpy and allow those areas to recover for at least a few months.
Not a strong opinion, just a consistent one.
