How long does the effect of the diet injection last?

Now that I'm actually thinking about weight loss injections and looking for a clinic, it's not easy to choose because there are so many types. There is a wide variety of methods, ranging from pen-type injections like Saxenda or Wigobi to fat-dissolving injections administered by clinics. Has anyone actually received a prescription for weight loss injections and taken them consistently?

I am also curious if you experienced any initial side effects, such as nausea or dizziness.

If you could share your honest reviews of the pros and cons from those who have personally paid for and received weight loss injections, it would be a huge help in choosing a clinic and making a decision. Please share your valuable experiences, even if it is just a small tip!
