Preparation & administration
Injection site rotation
Systematically varying the injection location to avoid tissue damage and erratic absorption.
In plain terms
Repeatedly injecting the same spot causes lipohypertrophy — thickened, lumpy tissue that absorbs unpredictably. Absorption from damaged tissue is slower and less consistent, which quietly changes the effective dose.
