Follow-up: A site rotation scheme that is easy enough to actually follow

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.

Not the answer, but possibly the question that gets there.

Where I part company with post #13, and it is a narrow parting.

Two claims get bundled together under site rotation scheme and they need separating. The descriptive one — this is what was observed — is usually well supported. The causal one — this is why — usually is not.

Almost every disagreement in threads like this one dissolves once you say which of the two you are making.

Understood, and I withdraw the assumption I opened with.

I had written a reply contradicting post #25 and deleted it. Here is what survived.

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.

That holds for the case as described. Change the assumptions and it may not.

Taking post #32 at face value and following it one step further.

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 am aware this is the third time this month I have made this point.

I have no financial interest in anything named in this thread and I want to say so before I comment on site rotation scheme, because it is the sort of subject where it matters.

Post #52 describes the usual case. This is about the unusual 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.

That is all I can say without guessing.

Confirming post #61 from a second method, which matters more than confirming it from a second person.

Angle of injection: 90 degrees into pinched tissue ensures subcutaneous placement. It is not always necessary and shallower angles can work, but 90 degrees into a small pinch is the safest technique to learn first.

A guess, clearly labelled as one.

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.
