I want to know about the obesity injection procedure in advance and prepare.

With an important event just three months away, I’m getting anxious because I’m not losing weight at all, so I’m considering getting weight-loss injections. I feel like I absolutely won’t be able to reach my target weight just by controlling my diet and doing cardio as usual. I’ve heard that weight-loss injections are the most effective way to get a defined figure quickly, so I feel like rushing to a dermatologist or internal medicine doctor right away. However, since time is running out, I’m most curious about when the effects will start to become noticeable. How many kilograms did people usually lose in the first month after increasing the dosage? I also want to know in advance if I tend to maintain my weight well once I stop the medication right after the event, so I can prepare accordingly.
