Site rotation, and why to write it down
Rotating injection sites is standard advice for anyone injecting regularly. The advice is simple; remembering where you went last week is not, particularly on a weekly schedule where each injection is seven days from the last memory of one.
Why rotation is generally advised
Repeatedly injecting the same spot is associated with local tissue changes over time, and those changes can in turn affect how a medication is absorbed from that site. This is why product instructions and clinicians generally advise varying the site between injections.
The specifics — which sites are appropriate for your medication, how far apart, and any you should avoid — are product-specific and belong to your product's instructions and your prescriber. This guide is about the tracking problem, not the clinical one.
The actual difficulty
On a daily injection, you remember yesterday. On a weekly one, you are recalling something from seven days ago that took fifteen seconds and was unremarkable at the time. Most people are confident they will remember and then are not sure.
What follows is predictable: an unconscious default to the most convenient site, which is the opposite of rotation. People often discover this only when they notice a change at that spot.
What a useful record looks like
It needs to be quick enough that you actually do it, and specific enough to be worth having.
- Site, with the injection. Not in a separate note — attached to the dose entry, so the two cannot drift apart.
- Enough specificity to be meaningful. "Left abdomen" is more useful than "abdomen"; if you use a quadrant or clock-position scheme, use it consistently.
- The previous site visible when you log the next one. This is the part that actually changes behaviour — seeing where you went last week at the moment you are deciding this week.
- Anything you noticed. If a site was tender or looked different, write it down. That is the observation you will want to be able to describe to a clinician later.
Peptide Plug records site per injection and shows your previous site when you enter the next one. It does not tell you which site to use — that is a matter for your product instructions and your prescriber.
A pattern beats improvisation
Most people who rotate successfully use a fixed sequence rather than deciding fresh each time. A defined order removes the decision, and a record tells you where you are in it. What the sequence should be depends on your medication and your circumstances, so agree it with your prescriber rather than adopting one from a diagram online.
When to raise something with a clinician
Persistent changes at an injection site — lumps, hardening, dents, discoloration, ongoing soreness — are worth showing to a clinician rather than working around. A dated log makes that conversation much more concrete, because you can say how long it has been there and how often that site was used.
