Please tell me the cost and effectiveness of weight loss injections!!

I want to succeed in my diet this time.

Since there are various types of weight loss injections, please explain the differences between them. Rather than an overly expensive procedure, I would like to choose one that is more affordable and actually helps with weight management.

Please let me know how many sessions of weight loss injections are typically required to see results, as well as the treatment cycle. I am also curious whether it is a one-time treatment or if I need to receive them consistently.

In particular, please let me know if the cost of weight loss injections varies significantly from hospital to hospital. Rather than spending a large amount upfront, I want to check the total cost and manage my weight in a cost-effective way.

If anyone has actually received weight loss injections, please let me know how effective they were and how much it costs to maintain the results. I would also appreciate it if you could share any methods that offered good value for money.
