Peptide chatter in my mom group: real or hype?

Tbh Two kids, 7 and 3, and our 5:30pm dinner is basically a snack-drawer raid: string cheese, pretzels, apple slices. I've been on a GLP-1 for 14 weeks and I'm down 18 lbs, but my 3pm brain still whispers about the pantry. Lately I keep seeing Dihexa, Cerebrolysin, P-21, IGF-1 LR3, Pinealon, SLU-PP-332, and myostatin inhibitors mentioned in random threads. I'm not asking for doses or sources, just curious what real life looks like for people who aren't bodybuilders or biohackers. Does anyone actually notice anything with these, or is it mostly noise and expensive pee? I'm too tired to chase a rabbit hole, but I'm also nosy. If you've tried any, what made you stick with it or drop it? Bonus points if you're also hiding veggies in pasta and forgetting your own vitamins.
