Complete Guide to GLP-1 Injection Sites
Proper injection site selection and rotation is one of the most important aspects of GLP-1 medication management. Whether you are taking Ozempic, Wegovy, Mounjaro, or Zepbound, understanding where and how to inject can improve absorption, reduce side effects, and prevent tissue damage.
Recommended Injection Sites
GLP-1 medications like semaglutide and tirzepatide are subcutaneous injections, meaning they go into the fatty tissue just beneath the skin. The three FDA-approved injection sites are:
Abdomen — The most common site. Inject at least 2 inches away from the navel. The abdomen provides consistent absorption.
Thigh — The front of the thigh, roughly the middle third. Avoid the inner thigh and areas near the knee.
Upper Arm — The back of the upper arm. This site may require assistance from another person.
Why Rotation Matters
Injecting in the same spot repeatedly can cause lipohypertrophy — a buildup of fatty tissue that forms hard lumps under the skin. These lumps can reduce medication absorption, making your dose less effective.
How OffGrid Dose Helps
OffGrid Dose tracks every injection site on a visual body map. Each zone is color-coded: green means ready, amber means recently used, red means avoid. The app recommends your next injection site automatically based on your rotation history.
Key Takeaways
- Rotate between abdomen, thigh, and upper arm
- Never inject in the same exact spot twice in a row
- Wait at least 1-2 weeks before returning to the same zone
- Track your sites with OffGrid Dose to automate rotation
