Stacking help

I’ve read through dozens of posts but could still use some help focusing on what’s best. I’ve lost 50 pounds on tirz and am about to add reta to help with the last 10 to 20, but I feel like I dove into a rabbit hole of peptides and they all sound amazing and I want them all!! I’m wondering what the right peptides to add are to help get rid of the last of the weight and belly flab while possibly also adding glow for the skin? Is this stacking too much? Every peptide I look at sounds amazing so I would love suggestions from experience. TIA!
