Peptide for fat loss no GI issues?

Hi - long story short I have tried tirz and reta, but I cannot deal with the GI issue getting longer. I have taken digestive enzymes, i take multiple tums a day, drink peppermint tea, etc but i feel the food on my chest and cannot handle the burping anymore. Worst part is the food noise has come back. I don’t feel appetite suppression any longer.

Is there a peptide that would help with fat loss but that doesn’t necessarily suppress appetite if that make sense. I have heard some people mention “Tesa” I was wondering what was everyone’s experience on that
