Do the diet injections work well?

I was stressed out because of the stubborn fat that wouldn't go away no matter how hard I exercised, so I started looking into diet injection treatments.

I have successfully lost some of my overall weight through diet control, but exercise alone hasn't been enough to tone down the underarm fat and double chin lines that I am most self-conscious about when wearing dresses. Hearing that medical intervention is the fastest way to sculpt specific body parts in a short period, I am frantically searching for prices and reviews on diet injections.

I am curious to hear raw, honest reviews from people who have actually paid for and completed the diet injection treatment at a hospital, rather than the promotional posts flooding the internet.
