I had HPL several times a long time ago and it was quite effective. When I suddenly gained weight, I was prescribed an appetite suppressant and I drastically reduced my food intake for a few days. The enlarged stomach shrunk and it was much easier to control my diet from then on. At the same time, I tried HPL, Carboxy, etc., but Carboxy was really very painful. With HPL, I had to wait for the injected solution to go away, which was also painful, but I think HPL had a good gel effect. When it comes to dieting, controlling your appetite is the top priority, and the rest is about taking care of your problem areas, so I think I was able to diet with more care.
