Intramuscular B12 injection sites If you prefer intramuscular delivery, the best places for B12 shots are often the rounded shoulder muscle (deltoid), the thigh, and the hip

Vitamin B12 injections are a prescription treatment used under the supervision of a licensed provider

Chang often recommends this site for patients who need regular maintenance doses of B12 and prefer a method thats easy to perform at home
