Summary
Peptides for midlife health are suddenly everywhere, but do they actually work or are they just the newest longevity trend? In this episode, Chalene Johnson sits down with longevity expert Dr. Elizabeth Yurth to break down the growing buzz around peptides and what women over 40 should know before jumping in.
You've probably heard about GLP-1 medications, BPC-157, collagen peptides, and growth hormone peptides, all promising benefits for weight loss, inflammation, muscle recovery, and anti-aging. But with so many supplements, injections, and online sources popping up, it's getting harder to tell what's legitimate and what's just hype.
Together, Chalene and Dr. Yurth unpack what peptides actually are, why they're suddenly everywhere in the longevity world, and why many experts believe peptide levels change as we age.
They also discuss one of the biggest risks most people don't realize until it's too late: where peptides are coming from and why the source matters far more than most people think.
If you've been curious about peptides, GLP-1 medications, or longevity therapies for women over 40, this conversation will help you start asking the right questions before deciding whether they belong in your midlife health routine.
