Sara went down a rabbit hole. It started with a quick weight gain she couldn't explain, a turning-45 reality check, and the sneaking suspicion that willpower wasn't going to cut it this time. So she started doing her research — like actually doing her research — and landed somewhere she didn't expect: peptides.

This week we break down what peptides actually are, how GLP-1 and GLP-2 are different (and why the difference matters), and the surprisingly good argument for starting with a peptide before you've even fixed your habits. Sara also explains the lego theory of aging — yes, really — and why the 10 pounds she's been sitting on for years finally started moving.

If you've been hearing about peptides everywhere and not really knowing where to start, this is your starting point. Sara lost 10 pounds. Zero side effects. Caleigh is already influenced. The rabbit hole officially has two of us in it.
