Injection Site Rotation Map
Track your subQ injection sites on a visual body map. Color-coded heat overlays show which zones need rest. All data stays on your device.
Next recommended site
Left deltoid
Based on your past entries, this rotation suggests Left deltoidas the longest-rested site. Always follow your prescriber's guidance for your specific protocol.
Why rotation hygiene matters
Subcutaneous tissue responds to repeated mechanical trauma by depositing collagen and adipose tissue at the injection site, a condition known as lipohypertrophy. Injecting into these hardened areas changes the absorption rate of the compound, making dosing less predictable over time. Consistent rotation across a set of anatomical zones reduces the cumulative burden on any single area.
A common rotation framework for subcutaneous use divides the injectable surface into distinct quadrants or zones: abdomen (periumbilical area), outer thighs, deltoid region, and upper-outer glutes. Cycling through these zones and allowing at least 7 days before returning to the same spot is a widely cited practice for peptide and insulin-class compounds. Your clinical team may specify a different interval based on your injection frequency.
This tracker is a workflow tool only. It records which zone you selected and when, and it surfaces the longest-rested zone as a suggestion. It does not know your substance, your dose, your needle size, or your anatomy. Follow your prescriber's guidance for all clinical decisions.
