Booty injections anyone?

Anyone (who keeps track of injection sites and their efficacy) ever give their shot in the backside?? Today was shot day, i usually use either side of my abdomen but for the last 3 weeks have been using my arm. The arm has been good to me with weight loss but I can hardly eat without being sick so today I tried the top of my booty meat. Minimal nausea but the food aversion kept hitting me during lunch.
