Peptides are suddenly everywhere. From anti-aging injections and collagen powders to skincare serums and “miracle” supplements, they’ve become one of the biggest wellness trends on the internet. 

But here’s the problem: most people have absolutely no idea what peptides actually are — or whether the products they’re using are helping them… or potentially harming them.

In this episode, I break down the science behind peptides in a way that actually makes sense. I explain why these tiny compounds play such a major role in how you age, recover, think, and feel — and why your body’s relationship with them changes dramatically over time.

I also share an important warning about the growing peptide craze, including what I’ve seen happen firsthand with patients who jumped on the trend too quickly.

If you’ve been curious about peptides or wondering whether they’re truly worth the hype, this episode will help you separate real science from clever marketing.

On this episode, you’ll learn: 

• Why peptides have suddenly become the hottest trend in longevity— and whether they actually live up to the hype
• The 4 completely different types of peptides most people confuse (and why that matters for your health)
• Which peptide category I personally believe is NOT ready for everyday use
• How aging quietly changes your body’s natural peptide production
• The dangerous mistake many people are making with trendy online peptide products
• What happened when several of my own patients experimented with injectable peptides
• The 3 things a well-designed peptide supplement should actually support if you want real results
• What peptides are really doing inside your body every single day
