Peptides aren't new, so why is my feed acting like they are?

I'm 54, the kids are launched, and I've been walking the same two-mile loop after breakfast while learning to cook with actual spices instead of just salt. The odd thing: every podcast and feed is suddenly talking about peptides like they were invented last year.

I remember a physical therapist mentioning them to a running buddy maybe fifteen years ago, and an old nutrition textbook at a used book sale had a chapter on them. So why now? Is it delivery, marketing, telehealth, or just that the culture caught up?

I'm not chasing anything, just curious from the cooking-and-walking sidelines. What made you first hear about them?

Ha, I posted about this in the old 2022 “incretin gold rush” thread — peptides get rediscovered every few years. What’s different now is the podcast economy needs a fresh hero/villain cycle, and GLP-1 chatter cracked the door open.

My n=1: I track protein, fiber, steps, and sleep in a boring spreadsheet, not peptides. The only peptide I hear about IRL is collagen at Costco, and that’s mostly marketing.

Genuine question: when your feed says “peptides,” are they talking about the same ones your PT mentioned, or has the word just gotten stretchy? I’d bet the latter.

Same whiplash here. I’m a daily weigher, so I treat my feed like scale noise: watch the 30-day trend, not the headline.

Concrete thing I noticed: “peptide” keeps showing up in old skincare ingredient lists and collagen tubs I bought pre-pandemic—same word, new packaging cycle. Once a term leaves the clinic and hits fitness influencers, every podcast seems to rebrand it as a discovery.

Sharp question: when your PT buddy mentioned them, was it about recovery habits/rest, or just a throwaway term? I’m curious whether the current hype is about the word or the boring basics.
