I'm curious about reviews from people who successfully lost weight using weight loss injections.

I've tried diet pills and personal training, but the yo-yo effect has sent me back to square one, so lately I've been diligently researching the cost of weight-loss injections. Prices vary quite a bit from clinic to clinic, and hearing that the monthly maintenance costs alone can easily amount to hundreds of thousands of won makes me hesitate to pay. While the results are said to be certain, I wonder if it's really worth it when I think about the money I'll have to spend every month. I get tempted when I see reviews from people around me who say they lost 10kg in just a few months using the injections, but my biggest worry is that I might gain it all back once I stop. I feel like it would be so pointless to spend a large sum on medication only to experience the yo-yo effect later. To those of you who have successfully lost weight using weight-loss injections, could you please share how many months you received them and roughly how much the total cost was?
