I'm curious about the method of administering the obesity injection.

I keep failing at dieting, so this time I'm thinking of trying weight loss injections. I've tried fasting several times and put in a lot of effort, but in the end, I'm resorting to getting help from these injections. However, I'm curious whether the procedure involves medical staff administering the prescribed injections directly at the clinic, or if I take them home to self-administer. I also want to know if there is a significant difference in irritation or pain depending on which injection method is chosen. For those of you who have received the procedure at a clinic, which method did you find more convenient and satisfying? I'm currently setting a budget to start visiting Maypure next month, haha. I really want to lose weight using a sure method this time.
