Injection Site Rotation App: A Visual GLP-1 Body Map
A body map can help you remember where you injected. It cannot decide that a site is safe, healed, optimal, or ready. Always follow the Instructions for Use (IFU) supplied with the exact product and presentation you use.
The current prescribing information and IFUs for Ozempic, Wegovy, Mounjaro, and Zepbound identify the abdomen, thigh, and upper arm as subcutaneous injection areas and direct users to change the injection site. Device steps and skin areas to avoid vary, so do not operate one brand using another brand's guide.
What “Rotate” Means in the Labels
The labels direct users to change the injection site with each injection. They also permit using the same general body region while selecting a different spot within it. The reviewed labels do not establish a universal number of zones, a one- or two-week healing interval, or a rule that everyone must cycle among all three regions.
Follow product-specific language about bruised, tender, hard, red, scarred, or otherwise affected skin. Ask a clinician about a persistent lump, swelling, pain, or skin change instead of relying on a color in an app.
How the OffGrid Dose Body Map Works
OffGrid Dose lets you tap one of eight organizational zones when logging an injection:
- four abdomen zones;
- left and right thigh;
- left and right upper arm.
The app records the date, dose information, and selected zone. Its colors summarize elapsed time in the app's history:
- green is an organizational “older entry” cue;
- amber indicates more recent use;
- red indicates the most recent use.
The colors summarize logged site history and recency only. The map does not determine tissue readiness, safety, absorption, or effectiveness, and the app does not recommend an injection site. Inspect the actual site and follow the product IFU. If the app and the IFU conflict, the IFU controls.
What the Map Cannot Tell You
The body map does not inspect tissue, diagnose lipohypertrophy, measure medication absorption, or guarantee that rotating will prevent a reaction. It also cannot know about a bruise, scar, rash, lump, pain, clothing friction, or clinician instruction unless you review those facts yourself.
Do not treat an elapsed-time recommendation as a prescribed injection schedule. The labels reviewed for this article do not provide a universal seven-week recovery cycle or say that the longest-rested zone is the medically optimal site.
Logging an Injection
On injection day:
- check the name and dose on the medication package;
- review the IFU for the exact device;
- inspect the candidate skin as the IFU directs;
- use the map only to review prior entries;
- administer the injection according to the IFU;
- record the actual site used.
If you are unsure whether the full dose was delivered, do not repeat it based on the log. Consult the IFU and contact a pharmacist or prescriber.
Different Products and Compounded Medication
The four branded labels cited above list the same three general body regions, but their device instructions are not interchangeable. Current labels also contain multiple presentations within some brands.
Compounded semaglutide or tirzepatide has no shared FDA-approved IFU. Follow the dispensing pharmacy's exact concentration, syringe, storage, and administration instructions. A branded product's angle, hold time, or device procedure should not be copied onto a vial-and-syringe product.
Reviewing the History With a Clinician
A simple history can answer factual questions:
- Which general region did I use last?
- Did a bruise or reaction follow a specific entry?
- Have I repeatedly selected one region?
- What device and dose did I record at the time?
It cannot answer whether a site altered absorption or caused a weight or symptom change. Describe the dates and observations without claiming causation.
Privacy
OffGrid Dose stores its working data on your iPhone. There is no OffGrid Dose account, company-operated cloud sync, or server-side health database, so OffGrid Dose does not receive your injection history. Depending on your Apple and device settings, an encrypted device backup may include app data.
Frequently Asked Questions
How many zones do I need?
The reviewed labels do not prescribe a universal number of custom zones. The eight-zone map is an organizational design, not a medical minimum.
Can I use any green zone?
Green only reflects elapsed time in the app. Check the actual skin and exact product instructions; ask a clinician about an unsuitable or concerning site.
Does the abdomen absorb GLP-1 medication faster?
The cited labels list abdomen, thigh, and upper arm without establishing a user-facing hierarchy that should drive site choice. Use a labeled site according to the IFU.
Does the map prevent lipohypertrophy?
No app can promise prevention. It can help you remember prior entries while you follow label instructions to change sites.
Does the same map work for compounded products?
It can record a general location, but it does not replace the compounded product's pharmacy instructions. Do not assume branded-device directions apply.
