Does the cost of weight loss injections vary significantly from hospital to hospital?

Lately, I feel like my body is sluggish compared to before when I get dressed, so I am looking for ways to manage it.

I have been trying to exercise and diet, but since I haven't seen the changes I wanted, I started looking into weight loss injections as well.

I searched online and noticed that the cost of weight loss injections varies quite a bit from hospital to hospital. I am curious whether the quote is usually based on a single session or if it is common to pay for a package.

I would like to know if there are any additional costs for the initial consultation, and how many sessions are required to achieve satisfactory results.

If anyone has received weight loss injections, it would be helpful for me to refer to them if you could share your honest experiences regarding whether you were satisfied with the cost-effectiveness.
