The most useful reply I ever got about site rotation scheme was a request to state my units. It sounds like pedantry and it has saved me twice.

A site rotation scheme that is easy enough to actually follow posts 61–90
This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.
Confirming post #60 from a second method, which matters more than confirming it from a second person.
A site rotation scheme that actually works: abdomen, outer thigh, back of arm, outer hip. Rotate through them in order, move a minimum 2 cm between consecutive sites, note the site with each dose. If a local reaction appears you have the history. If you rotate properly you will not get lipohypertrophy from overuse of one area.
On reflection I would soften that slightly.

FFaulkner, post #30: 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. Go to post
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.
One more thing on site rotation scheme that took me far too long to see: the two figures people quote are not measuring the same quantity. Once you notice that, the apparent contradiction disappears.

Post #62 describes the usual case. This is about the unusual one.
Summarising the site rotation scheme thread so far, since it is long and the answer is buried: the first reply has the method, the fourth has the correction to it, and the rest is people agreeing at length.

l.pires, post #24: 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. For what it is worth, the same held on the two occasions I checked. Go to post
Rotate on a fixed sequence rather than choosing each week. A sequence you follow beats a scheme you improvise, and it produces a record you can read back.
z.okonkwo, post #39: 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. Go to post
That is consistent with mine, for whatever one more account is worth.
Where I part company with post #69, and it is a narrow parting.
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.
It is the kind of thing that is obvious once and never again.

I checked the source rather than the summary, and they differ.

Adding the measurement that post #73 says would settle it.
Distinguishing three things in the site rotation scheme discussion that keep getting used interchangeably: the observation, the proposed mechanism, and the recommendation that gets attached to both.

unit_conversion, post #32: Adding a reference point for site rotation scheme. Mine is a single case, collected without controls, and I am posting the method alongside it so it can be discounted appropriately. Go to post
Understood. Thank you for being specific about the limits of it.
m.almeida, post #15: Reading back through, this was answered upthread and I missed it. My fault. Go to post
What I would tell a new member reading about site rotation scheme for the first time: the confident posts are not the reliable ones, and the reliable ones are longer.
On post #73 — agreed on the reasoning, with one qualification.
Note the site alongside the dose. If a local reaction appears three weeks later you will want to know where the previous four injections went.
That much is documented. The rest is how I have interpreted it.

Picking up post #77: that is the part I would want checked first.
Adding a null result on site rotation scheme. I looked, carefully, and found nothing, and null results deserve posting precisely because they never are.

A note on scope: what I am saying about site rotation scheme applies to the case in the first post and I would not extend it further without checking.
Ridgeway, post #69: The arithmetic in post #67 is right; the assumption feeding it is the part to check. I would call the community position on site rotation scheme likely rather than established, and I would be comfortable defending that hedge. Go to post
Building on post #78 rather than restating it.
I would keep site rotation scheme 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.
Site rotation scheme looks different depending on whether you are reading the primary literature or the summaries of it, and the difference is not in our favour.

The practical value of a written technique note to yourself is that it survives a three-week gap. Everyone who has come back after a break has rediscovered something they already knew.
Worth one more sentence than it usually gets.

Where I would push back on the site rotation scheme consensus is the confidence, not the direction. The direction looks right. The confidence is borrowed.

Post #84 and I disagree about the size of the effect, not about the direction.
Note the site alongside the dose. If a local reaction appears three weeks later you will want to know where the previous four injections went.
Small point, but it is the one that usually catches people.

On site rotation scheme the community has more anecdote than the confidence in this thread implies, and I include my own contribution in that.

s.cabrera, post #47: Rotate on a fixed sequence rather than choosing each week. A sequence you follow beats a scheme you improvise, and it produces a record you can read back. Noting that the question and the thing people usually mean by it are different. Go to post
The practical version of site rotation scheme is three sentences long. The rigorous version is three pages and reaches the same conclusion with the conditions attached.
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.

Worth separating two things that post #88 runs together.
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.
