Is there a significant difference in the effectiveness of Maunzaro injections depending on the body part?

When administered via Maunzaro

Is there a difference in the pain or stiffness felt depending on the injection site, such as the abdomen, thigh, or forearm?

Especially if you place it on an area with little subcutaneous fat and a bit more muscle

Is the pain or tingling sensation stronger?

My body fat tends to be hot, and since I don't have much muscle, I was worried about where to inject it in case of an emergency.

It would be very helpful to know if you felt a difference depending on the area, and which location was the most comfortable and least burdensome.
