How to Keep Track of Injection Site Rotation (Without a Notebook)

Rotating injection sites is standard practice for anyone on a regular injectable schedule. Remembering where you went last week is not. By week three most people are guessing, and guessing is how one spot ends up overused.

Note: this article is about record-keeping. Which sites are appropriate for you is a question for your healthcare provider.

Why memory fails here

Injection-site decisions happen in a few seconds, usually first thing in the morning or last thing at night, often on a weekly schedule. That's the worst possible setup for memory: infrequent, routine, and nearly identical each time. "Left side or right side last time?" is genuinely hard to recall seven days later.

Simple rotation systems

Any system works if you log it. Common ones:

• Clockwise pattern: move around a fixed set of sites in the same order every time.
• Alternating sides: left/right alternation, plus moving within each side.
• Weekly zones: one zone per week, with rotation inside that zone.

The system matters less than the record. A paper note on the fridge works until the day you're traveling.

What a good site log captures

1. The site (and side)
2. Date and time
3. Which compound/schedule it was for (if you track more than one)

With that, the question "where did I go last time?" has an instant answer, and patterns of overuse become visible.

Logging sites in PepMinder

PepMinder (free on Android) lets you log the injection site each time you log a dose, and shows the site you used last. Your rotation history sits next to your dose log, so you see the last sites used before you pick the next one.

Everything is stored locally on your phone: no account, no cloud.
