Pinch or no pinch, and how needle length changes the answer Writing it up because I had to work it out twice and would rather nobody else did.
A question about pinch that I think has a definite answer, unlike most of what I ask here.
I have the reasoning below and I am fairly confident about the direction. I am not confident about the size, and the size is what the decision turns on.
Reading rather than answering, but this is the post I would point somebody at.
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.
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.
Pinch: I would want to see the raw numbers rather than the summary before agreeing. Summaries lose exactly the information that would settle this.
Taking post #5 at face value and following it one step further.
A new needle for each injection is not fussiness. A needle blunts on first use and a blunted needle is the reason the second injection hurts more than the first.
Happy to expand any of that if it is the useful part.
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.
Posting it because the silence on this was starting to look like agreement.
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.
Second-hand, so weight it accordingly.
Saving this. It is the version I will quote when the question comes round again.
Building on post #8 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.
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.
A definition problem is doing most of the work in this pinch discussion. Once the term is pinned down I suspect the disagreement mostly goes away and what is left is small.
Post #16 describes the usual case. This is about the unusual one.
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.
The right answer here may simply be that it has not been measured.
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.

Not disagreeing with anyone above, just adding the bit I keep having to look up.

It is worth stating the boring hypothesis before the interesting one.
Building on post #21 rather than restating 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.
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.
That is a description of practice, not a recommendation of it.
Offering a way to settle pinch rather than another opinion about it. Two measurements, taken the same way, a fortnight apart. If the difference is within the noise, the question was not answerable at this precision.
Clear enough that I do not think I have a follow-up, which is unusual.
Post #25 is the version of this I will quote in future. One addition.
Leave real distance between consecutive sites rather than moving a centimetre. Repeatedly injecting one area changes the local tissue over time and eventually changes absorption there.
Adding a source would improve this post and I do not have one to hand.

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.
Adding the measurement that post #29 says would settle it.
