I put my pods anywhere I can pinch up the skin and put pods in places where I would never think to inject. There does not need to be fat - just enough skin to get the canualla in without hitting the muscle.
@michel - Thanks to some internet people here are the “site locations” that I rotate my pod through. There are about 32 locations so if I rotate the pod that becomes about 64 sites in total. As I said, I rotate in a clockwise direction from my right spine to my left spine and then to my left arm and right arm. So the two sites on the arm see a lot more action than the area on my body. (i.e. I will do the top row on the body then arms - then the middle row - then arms - then the bottom row - then arms).
